Roadmap and Change Log
paint.net 4.2.14 - released on October 23, 2020
This updates adds full support for AV1 (*.avif) images, includes many optimizations to improve performance, CPU usage, and memory usage, and also has several important bug fixes.
- New: AV1 (*.avif) images can now be saved (not just opened), due to bundling of @null54's AvifFileType plugin (v18.104.22.168). Installation of Microsoft's codec from the Microsoft Store is no longer necessary, which means this also works on Windows 7 and 8.1.
- Improved performance and memory usage in the canvas rendering engine, especially when working with large images or images with many layers. This is most noticeable when scrolling and zooming.
- Improved CPU usage when a selection is active and when GPU accelerated rendering is disabled
- Improved CPU/GPU usage when a selection is active but the app is not (the animation is disabled)
- Reduced memory usage when working with images that have regions of solid color
- Fixed the Magic Wand and Paint Bucket tools so that they do calculations in the premultiplied alpha color space. This ensures that transparent colors (alpha=0) with different RGB values are treated as equal, and do not create borders.
- Fixed the Move Selected Pixels tool so that it fills the uncovered region with 0 (transparent), instead of a transparent version of the secondary color.
- Fixed: Backspace now works correctly in the Colors form: it does not execute Edit → Fill Selection
- Fixed an issue where saving an image at 4-bit color depth (usually pixel art) was using an incorrect palette (reduced color count/quality). This was due to a bug in Windows Imaging Component (WIC).
- Greatly improved performance when saving images at 8-bit color depth
- Fixed an issue where very large images (e.g. 50000 x 50000 px) couldn't be saved at indexed bit-depths (8-bit or less) due to a bug in Windows Imaging Component (WIC). More information on the forum: https://forums.getpaint.net/topic/116950-error-when-saving-a-big-file/
- Fixed an issue where BMP images couldn't be loaded if they had the .PNG extension (there's an Android screenshot utility out there which does this ...)
- Improved: Ellipse Selection Tool's now tessellates at a higher resolution, resulting in smoother circles at small sizes
- Fixed a rare crash in the Gradient tool ("The tool must be in the Drawing state ...")
- New: Added a list of the DLLs that are loaded into the process on the Settings → Diagnostics page. This is to help troubleshooting scenarios.
- Fixed an issue with copying large images to the clipboard: if an image would take up more than 4GB, it could not be copied because the DIB and DIBV5 formats cannot be larger than that. Now, the DIB and DIBV5 formats are not placed on the clipboard if this happens.
- Fixed an issue with Effect plugin tooltips which was preventing the menu item from being easily clicked (thanks @toe_head2001 for the fix!)
- Fixed an issue that was preventing Effect configuration dialogs from working correctly in the Visual Studio designer (thanks @toe_head2001 for the fix!)
- Added diagnostics information to most error dialogs. This is to help with troubleshooting.
- Fixed: Scanning will now apply the DPI (resolution) from the scanner to the image, if possible
- Updated bundled DdsFileTypePlus plugin to v22.214.171.124. See the pdn-ddsfiletype-plus change log on GitHub for more information. Thanks @null54!
paint.net 4.2.13 - released on August 4, 2020
This update adds some additional low-bit-depth choices to
several file types (PNG, BMP, TIFF), and fixes some bugs.
- New: Added 2-bit per pixel support when saving as PNG
- New: Added 1-bit per pixel support when saving as PNG, BMP, and TIFF
- Fixed low-bit-depth saving quality (8-bit, etc.), as it would sometimes produce very bad results (e.g. only using 64 colors instead of 256)
- Fixed: Resizing an image at very large sizes (e.g. 32K pixels to 64K pixels) would fail due to an arithmetic overflow
- Fixed: Sometimes recently saved images would not have an updated thumbnail in File Explorer unless/until its window was manually refreshed
- Fixed: Sometimes saving an image to a network share would not work
- Updated bundled DDSFileTypePlus plugin to version 126.96.36.199, which fixes an issue when loading and saving images using the sRGB color space. This issue was reported here. Thanks @null54!
paint.net 4.2.12 - released on May 29, 2020
This is a hotfix for a few important issues that have come to light with the 4.2.11 release.
- Fixed an error that was preventing some old PDN images from loading (reported here: https://forums.getpaint.net/topic/116501-error-opening-older-pdn-files/)
- Fixed a crash in the new selection outline renderer (due to misaligned Push/PopAxisAlignedClip calls)
- Changed saving to use the ReplaceFile Win32 API, which improves its compatibility
- Fixed an EndOfStreamException error that prevented some JPEGs from opening (thanks @null54 for the fix!)
paint.net 4.2.11 - released on May 20, 2020
This update adds XMP metadata support, 3 new translations, some UI improvements, and several bug fixes.
- New: XMP metadata is now preserved for supported file types (PDN, JPEG, PNG, TIFF, JPEG XR, HEIC, AVIF, WEBP)
- New: Belarusian (be) translation
- New: Greek (el) translation
- New: Slovenian (sl) translation
- New: Added a right-click context menu to the image thumbnail/tab. It contains commands for Copy Path, Open Containing Folder, Save, Save As, and Close.
- New: The items in the File -> Open Recent menu now have a tooltip with the full file path for the image
- Changed: The selection outline animation is now smoother (2x the framerate)
- Fixed: Saving with the HEIC file type is no longer limited to a max Quality value of 90. This limitation was in place because of a crash due to heap corruption, which no longer happens.
- Fixed: The NVIDIA sharpening setting will no longer cause trippy distortions in the canvas area
- Fixed an issue with loading very small TGA images, first reported here:
https://forums.getpaint.net/topic/116100-tga-rle-truecolor-1x1-image-failed-to-load/. Thanks @null54 for the fix!
- Fixed: Error dialogs when opening images now consistently show the file path
- Fixed a PropertyNotFoundException error message when saving JPEG images with a particular ordering of metadata. This was due to a bug in Windows 7's WIC JPEG codec. First reported here:
- Fixed clipped text rendering in the Curves adjustment dialog in some non-English translations.
- Fixed a crash when running the app with a DPI scaling setting of 500%
- Fixed a crash that would sometimes happen when running effects with very small selections
- Fixed some IndirectUI controls not honoring their default values if also initialized in read only (disabled) mode. Thanks @BoltBait for the fix!
- Fixed a memory leak in the effect system that was causing 1 orphaned thread per effect invocation
- Changed: Removed the use of NTFS Transactions, which was causing trouble with OneDrive. Microsoft has also
deprecated this technology.
- New: Added /openCrashLogFolder command-line argument. This is intended for simplifying troubleshooting workflows.
- New: Added /forceUpdateCheck command-line argument. This is intended for troubleshooting scenarios to simplify acquiring the latest version, e.g. "just run
paintdotnet:/forceUpdateCheck" instead giving a longer list of buttons to click on.
- Updated WebPFileType plugin to version 188.8.131.52, which adds XMP metadata support. Thanks @null54!
- Updated DDSFileTypePlus plugin to version 1.10.3. This fixes an issue with saving in the A1R5G5B5, A4R4G4B4, and R5G6B5 formats, and adds support for reading files that use a 'BC7\0' FourCC. Thanks @null54!
paint.net 4.2.10 - released on February 13, 2020
This small update fixes a few important bugs, most notably with installations that directly use the MSI file for deployment (e.g. AD/GPO).
- Fixed: Installations that directly use the MSI (e.g. AD/GPO deployments) no longer need to run the repair process immediately after installation. Some important DLLs were not being updated because while their assembly version was different, their file version was unchanged, so Windows Installer incorrectly skipped over them.
Click here for more information.
- Fixed: Loading an image with an enormous photoshop:DocumentAncestors node in the XMP metadata will no longer hang the app
- Fixed a rare crash in the auto-updater UI related to font initialization
- Improved performance when clicking OK on an effect or adjustment dialog that has already completed part of its rendering
paint.net 4.2.9 - released on January 31, 2020
This updates improves performance and significantly reduces memory usage, adds two new translations, and fixes a number of small issues.
- Reduced overall memory usage (commit size) by up to 1/3rd by eliminating the per-image scratch buffer
- Greatly improved performance when finishing actions of most tools by employing a shared cache between the render and commit code paths
- Reduced memory usage when working with many tools by consolidating homogenous tiles (those that are comprised of a single color value)
- Significantly improved performance of most history actions (commit, undo, redo) by switching from NTFS compression to multithreaded LZ4 compression for history files
- Significantly improved performance of undo/redo with very complex selections (e.g. from the Magic Wand tool)
- Improved performance of Image -> Flatten (also affects flattening when saving)
- Improved performance of the Invert Colors and Desaturate adjustments by disabling hardware acceleration for them (too much overhead in copying tiles to the GPU for such trivial rendering kernels)
- Improved performance when saving by moving thumbnail rendering for the File -> Open Recent menu to a background thread
- Reduced memory usage when printing, and removed a rare crash that was related to its use of the (now removed) scratch buffer
- Improved performance of effect rendering when a complex selection is active (improved caching)
- New: Added a "busy spinner" to the canvas when using the Magic Wand and Paint Bucket tools
- New translation: Hebrew (HE)
- New translation: Slovak (SK)
- Fixed a really goofy crash that required drawing with the paintbrush and, without letting go of the mouse button, moving the mouse into the toolbar and then using the mouse wheel to change the brush width
- Fixed a layout bug with the image list button
- Fixed an error that prevented saving some images as JPEGs if they had EXIF Interop metadata (PropertyNotFoundException)
- Fixed a crash when running on a CPU that supports AVX but with an OS that is configured to not support it (via bcdedit /set xsavedisable 1)
- Fixed a crash when pressing the spacebar after switching to a tool but before it has received any mouse input events
- Fixed a rare crash when opening the Levels adjustments with certain types of selections
- Fixed a crash when checking for updates with an expired alpha/beta build
- Fixed a crash (FileLoadException) when DLLs are not updated correctly by the updater
- Updated WebPFileType plugin to version 1.3.2 (thanks @null54!)
- Updated DDSFileTypePlus plugin to version 1.9.9. This adds support for X8B8G8R8 and R8G8B8 formats, and fixes a visual glitch when previewing cube maps in some formats.
paint.net 4.2.8 - released on December 3rd, 2019
This small update fixes a few pressing bugs, particularly for touch and pen input.
- Fixed: Pinch-to-zoom was not working when using a touch screen (regression in 4.2.6)
- Fixed: Spacebar panning was not working when using a pen/stylus (regression in 4.2.6)
- Fixed: EXIF metadata with non-ASCII characters is now preserved correctly
- Fixed a crash that can happen when the Microsoft Store version of the app is closed for an update
- Added /repair command-line argument, which will run PdnRepair.exe. This makes it easy to use Start -> Run ->
paintdotnet:/repair so you don't have to go fishing for the installation directory.
paint.net 4.2.7 - released on November 25th, 2019
This hotfix addresses a crash at startup that was happening on some systems.
- Fixed a crash at startup (FileLoadException) due to 1) the stub for System.Runtime.dll not being updated, and 2) the rigid version binding policy that prevented the older version from working in its stead (which would've been fine in this case).
paint.net 4.2.6 - released on November 21st, 2019
This update is focusing on some important fixes and performance improvements, and getting some infrastructure ready for future releases so that pens and tablets with pressure sensitivity can be fully supported (planned for v4.3).
- Improved the input handling systems to use WM_POINTER, which enables glitch-free drawing when using a pen or stylus (e.g. Surface Pen, Wacom/Ugee tablet) (see here:
https://forums.getpaint.net/topic/113173-the-first-5mm-of-a-freehand-line-are-straight-when-using-a-tablet/ ). This will also be the basis for adding pressure sensitivity in a future release (v4.3).
- Added a "Native pointer input" setting if a "pointer" device is available (pen, tablet, touch screen). Disabling this will cause any pointer device to be emulated as a mouse, which may be more compatible but at the cost of smoothness. Pointer devices are listed in Settings -> Diagnostics.
- Removed the "Fluid mouse input" setting because the use of GetMouseMovePointsEx() has been removed (it's a very buggy and broken API). This finally fixes a number of weird issues related to erratic or "scribbly" drawing.
- Improved performance of Move Selected Pixels, Shapes, and Gradient tools when releasing the mouse button at the end of drag-and-drop gesture. Previously, anything rendered between the last mouse "move" and "up" events was re-rendered, resulting in the appearance of a delay/lag.
- Greatly improved performance of layer thumbnails when switching between images
- Improved: The image list at the top can now be scrolled by clicking the arrow buttons and holding the mouse down, just like a regular scroll bar button. (Previously you had to click repeatedly). This improves usability, but was also noted as being important for accessibility.
- Improved: Smooth scrolling animations have been removed from the image list and layers list due to them just not working very well.
- Improved window chrome/theming when the app is running in Remote Desktop on Windows 10
- Changed: The size of the default/initial image ("Untitled") is now scaled exactly by system DPI setting (previously scaled by integer/floor of DPI setting). So at 150% DPI scaling this image will now be 1200x900 instead of 800x600.
- Fixed some high-DPI layout bugs with the Layer Properties dialog, while also preparing this UI for future additions
- Fixed a crash (OutOfVideoMemoryException) on systems with hybrid GPU setups that are configured wrong. This seems to be a bug in Windows and DirectX. A "hybrid GPU" setup is an Intel iGPU or AMD APU paired with a discrete GPU in a laptop.
- Improved handling of the dreaded "NoHardwareDeviceException" crash: The user will be notified of how to fix this. It happens only on 2nd generation Intel Core systems with NVIDIA "Optimus" GPUs (GeForce or Quadro) when the NVIDIA Control Panel is set to force apps (or just Paint.NET) to use the NVIDIA GPU. This is a bug in the NVIDIA driver and/or in DirectX.
- Fixed images being pasted incorrectly from Outlook 2016/365. This is actually a bug in Outlook: it puts PNGs on the clipboard that are arbitrarily cropped and scaled for some reason, and specifies they are the preferred format to use when pasting. This completely boggles my mind, it's just really weird, I can't imagine why it's done this way.
- Fixed some clipboard image handling for plugins (regular Copy/Paste is unaffected)
- Changed: SSE2 is now required for 32-bit/x86 systems (prevously, only SSE was required). See blog post:
- Updated bundled WebPFileType plugin to v184.108.40.206 (thanks @null54!)
- Updated bundled DDSFileTypePlus plugin to v220.127.116.11 (thanks @null54!)
paint.net 4.2.5 - released on October 1st, 2019
This update adds WebP (*.webp) support and fixes a few important bugs.
- New: WebP images are now supported due to bundling @null54's excellent WebPFileType plugin (v18.104.22.168)
- Fixed: Pasting images from Firefox's "Take a Screenshot" feature was resulting in swapped red and blue channels due to mishandling of DIB_V5 clipboard data using the BI_RGB value for bV5Compression (thanks @null54 for the fix!)
- Fixed crash at startup (for both app and installer) on Windows "N" editions due to missing mfplat.dll (Media Foundation Platform)
- Updated bundled DDSFileTypePlus plugin to v22.214.171.124
paint.net 4.2.4 - released on September 20th, 2019
This hotfix addresses some crashes and hangs that were happening when saving DDS images in certain formats.
- Fixed a hang, which sometimes also resulted in a crash, when saving DDS images in certain formats (e.g. BC1/DXT1)
- Improved: Reduced CPU usage in the COM interop system, which should help reduce overall power consumption
paint.net 4.2.3 - released on September 19th, 2019
This hotfix addresses an issue that was preventing DDS images from working on some systems.
- Fixed: A missing DLL, vcomp140.dll, was preventing the bundled DDSFileTypePlus plugin from loading on some systems
paint.net 4.2.2 - released on September 18th, 2019
This update adds AV1 (*.avif) loading support, significantly improves DirectDraw Surface (DDS) support, adds 4-bit saving for PNG, BMP, and TIFF, fixes several bugs, and optimizes startup time.
- New: AV1 (*.avif) images can now be opened (saving is not supported). Windows 10 v1809+ and Microsoft's AV1 Codec are required (download: https://www.microsoft.com/p/av1-video-extension-beta/9mvzqvxjbq9v )
- New: DirectDraw Surface (*.dds) support has been greatly improved due to bundling @null54's DDSFileTypePlus v126.96.36.199 plugin. All DX10/DX11 formats should now be supported (e.g. BC4, BC5, BC6H, BC7), and encoding (saving) will make use of the GPU to greatly improve performance. Note that it's no longer necessary to use the ".dds2" file extension.
- New: 4-bit saving is now supported for PNG, BMP, and TIFF
- New: The palette selection menu will now indicate which palette is currently active (thanks @null54 for the implementation!)
- Improved: The maximum image size is now 262,144 x 262,144 pixels, up from 65,535 x 65,535 pixels. This is mostly for accommodating very tall or very wide images.
- Improved: Startup performance has been improved for multi-core CPUs
- Improved: Startup performance has been improved when a lot of custom shapes are installed
- Fixed: EXIF metadata of type Float and Double are now supported. This ensures GeoTIFF metadata is preserved.
- Fixed: Opening an image should no longer flicker due to the transparency checkerboard being drawn first
- Fixed: TGA images that are 16-bit with 1-bit alpha with a zero'd out alpha channel are now treated as opaque. This allows images from 5CC Map Maker (for Close Combat modding) to work. Thanks @null54 for the fix!
- Fixed: JPEG XR's file extensions (*.jxr, *.wdp, *.wmp) are now registered with Explorer
- Fixed: Pasting images that use RGB pixel ordering should now work (this affects PaintTool SAI)
- Fixed a crash when manually typing in a very large number for the zoom level in the status bar
paint.net 4.2.1 - released on August 7th, 2019
This update addes JPEG XR file type support and fixes several important issues and crashes.
- New: JPEG XR file type support (Windows 8.1+ required)
- Fixed: Holding Ctrl when dragging a selection with Move Selected Pixels will again leave a copy behind (but only with the mouse)
- Fixed crashes when saving DDS images
- Fixed VTF file type plugin. It was not working in 4.2 except for images that were an exact power-of-2 size on each dimension.
- Fixed: .BMP files can be opened even if they're not actually BMP images (they still need to be a valid WIC-supported file type such as PNG, JPEG, etc.)
- Fixed very bad performance when opening large images with embedded rotation metadata
- Fixed various crashes, such as when using File->New or Image->Resize, that sometimes happened if the previous update needed a reboot but either 1) it didn't tell you that, or 2) it did but you didn't reboot
- Fixed the problem that was causing the need for the aforementioned reboot in the first place (string resources file was locked by the thumbnail provider shell extension)
- Fixed: Text tool will no longer draw tiny text when an image uses dots-per-centimeter instead of dots-per-inch
- Fixed menu ordering of effect plugins that have duplicate names
- Fixed: The mouse wheel may now be used to scroll the Palettes menu in the Colors window (thanks @AndrewDavid for the suggestion and @toe_head2001 for the fix!)
- Fixed metadata handling that was preventing some images with EXIF tag 330 from being able to load
- Fixed metadata preservation for old images that pad EXIF string values with null terminators
- Fixed title bar text color when using certain custom accent colors in Windows 10
- Fixed title bar accent color when Tablet Mode is enabled
paint.net 4.2 - released on July 13th, 2019
This is a big update that focus on adding HEIC file format support, fixing performance with very large images, and upgrading and modernizing the functionality of many existing file types (JPEG, PNG, BMP, GIF, and TIFF). Many other quality of life issues have also been addressed or fixed.
- New: Support for loading and saving HEIC images (Windows 10 v1809+ and
codec installation is required). Please note that the "Quality" slider when saving is limited to a value of 90 (out of 100) while Microsoft investigates and fixes a crash in their codec.
- New: Keyboard shortcuts for changing the current layer. You can see these in the Layers menu with the "Go to ..." commands. Alt+PgUp/PgDown will go to the layer above/below, and Ctrl+Alt+PgUp/PgDown will go to the top/bottom layer.
- Fixed: Optimized rendering engine to remove huge lag spikes (30+ seconds) when zooming or panning very large images (e.g. 32K x 32K pixels).
- Improved: BMP now supports saving in 32-bit (with alpha!) and 8-bit indexed.
- Improved: Added DIB and RLE file extensions to the BMP file type.
- Improved: PNG, JPEG, and TIFF now support loading and saving of much larger images.
- New: PNGs can now be saved as "interlaced".
- Improved: JPEG now has configuration for the chroma subsampling mode (4:4:4, 4:2:2, and 4:2:0). The default is now 4:2:2 instead of the unconfigurable 4:2:0 of older versions. This may result in larger file sizes, but higher quality, as compared to previous versions.
- Improved: TIFF now supports saving at 24-bit and 8-bit color depths.
- Improved performance of saving for file types where "Auto" bit-depth is supported but is not the current choice.
- Improved temporary memory usage when saving images at 8-bit color depth.
- Improved: TGA images now load about 4x faster (thanks @null54!)
- Fixed: 8-bit TGA images should now load correctly (thanks @null54 for the fix!)
- Fixed: Some 32-bit TGA images were showing up as completely transparent due to their use of an obscure alpha channel type (thanks @null54 for the fix!)
- Improved: Added error reporting to the Save Configuration dialog. Instead of just saying "Preview: (error)", you'll also get the standard error dialog that includes the exception which can used for troubleshooting.
- Fixed a number of performance issues in the Save Configuration dialog. Especially with large images, it should now be much faster to change options and to click OK/Cancel.
- Fixed flickering in the Save Configuration dialog when changing options.
- Fixed: Windows Explorer thumbnails for some image types (PDN, DDS, TGA) were not rendering their alpha (transparency) correctly, resulting in color skew. You may not see the effect of this fix for a particular image until that image is resaved or you clear Explorer's thumbnail cache.
- Fixed: Mouse cursors now scale appropriately for non-integer UI scales (e.g. 125% or 175%)
- Fixed: AltGr should now work correctly with the Text tool. It will not trigger shortcuts like File->Save All, or Edit->Paste into New Image. (thanks @Bruce Bowyer-Smyth for the fix!)
- Changed: Image->Resize supports Super Sampling again, and favors this over Fant when using Best Quality. Fant is still available, but is no longer chosen automatically.
- Changed: Holding Ctrl when starting to move a selection with the Move Selected Pixels tool will no longer leave behind a copy of the selected area
- Fixed: Bicubic resampling in the Move Selected Pixels tool was not correctly handling the alpha channel in some cases. This fix has required a reduction in performance.
- Improved: When using Edit->Copy, a 32-bit BGRA bitmap in the DIBV5 format is now placed onto the clipboard so that other apps can read the alpha channel.
- Improved: When using Edit->Paste, DIBV5's are now supported if they have an alpha channel. If they don't, then the regular DIB loader is used which has some heuristics for detecting an incorrectly defined alpha channel and correcting for it.
- Improved: When using Edit->Paste, PNG is now the highest priority format. This maximizes the ability to maintain alpha/transparency, but it does mean that images coming from Microsoft Office apps will appear larger than they used to. This is either a bug or a feature of Microsoft Office. For some reason it places PNGs on the clipboard that are 25%+ larger than the DIB/DIBV5 bitmap that it also places on the clipboard (but which don't have alpha/transparency).
- Fixed: DIBV5 bitmaps should now work with Edit->Paste, which improves alpha channel handling. (thanks @null54 for the fix!)
- Fixed: Top-down DIBs should now work correctly with Edit->Paste. (thanks @null54 for the fix!)
- Improved CPU usage for thumbnail updates (layers and image tabs) in many cases.
- Improved: Slightly increased the size of the Settings dialog to reduce the need for scrolling in a few important situations
- Fixed: Simple message boxes can now be closed with the ESC key
- Fixed: Magic Wand now works on very large images (e.g. 65535 x 65535 pixels) without an error.
- New: Plugins that use IndirectUI can now use a UriProperty with a LinkLabel control (thanks @null54!)
- New: Effect plugins can now more easily make use of the clipboard via the IClipboardService. It will handle all of the tricky clipboard issues such as threading, native data marshaling, and avoiding security vulnerabilities that exist in the standard WinForms and WPF clipboard APIs.
- New: FileType plugins can now specify separate lists of extensions for loading and saving.
- Blocked the WebP FileType v188.8.131.52 plugin due to instability. An update is already available.
- Blocked the ImAgif FileType v0.12.0.1084 plugin due to incompatibility. An update will hopefully soon be available.
paint.net 4.1.6 - released on March 18th, 2019
This update focuses on refreshing the app's theming with new high-res icons and improved support for high-DPI configurations. Some new menu commands have been added, such as File -> Save All, and a Turkish translation has been added.
- New: Completely redone high-res icons throughout the app which match the Microsoft Office style guidelines, with native support for up to 400% scaling (384 DPI)
- New: File -> Save All (thanks @Bruce Bowyer-Smyth!)
- New: Turkish language
- New: Move Layer commands are now present in the Layers menu, not just on the Layers window
- New: Layers -> Rotate 180 (thanks @null54!)
- New: Plugins can now use the UIScaleFactor class, which simplifies making decisions about DPI and scaling
- Improved: Image thumbnail list at the top of the main window now reacts to horizontal mouse wheel or trackpad swiping
- Improved: The Text Tool's "Font Size Metric" button now has a tooltip explaining it
- Improved: When many images are open, Paint.NET now closes significantly faster (thanks @Bruce Bowyer-Smyth for the fix!)
- Improved: File -> Open Recent now has up to 10 images (up from 8 )
- Changed: Ctrl+Shift+F6 and +F7 will now also reset the floating window sizes for History and Layers, respectively (same if you Ctrl+Shift+Click on the button at the top-right of the main window)
- Changed: (for plugins) EffectFlags.SingleRenderCall is deprecated. Plugins should use the new EffectRenderingSchedule.None option instead.
- Changed: Settings -> Plugin Errors now shows up even if there are no plugin errors. This ensures consistency, especially with the newly asynchronous nature of plugin loading (otherwise there's no way to distinguish "no errors" from "not done loading plugins").
- Fixed: Items in the File -> Open Recent menu will no longer get bigger or smaller when moving between monitors with different DPIs
- Fixed: An icon handle was being leaked every time a dialog was opened (thanks @null54 for the fix!)
- Fixed a crash when running GPU effects (e.g. Black & White) on very large, very tall images
- Fixed: "Bad" plugins can no longer ruin the undo system by rendering outside of the selection (thanks @BoltBait for helping out with this!)
paint.net 4.1.5 - released on December 4th, 2018
This update focuses on improving performance (sometimes significantly) and fixing important bugs.
- Improved: Image -> Rotate should now complete almost instantly (thanks @Bruce Bowyer-Smyth!)
- Improved: Optimized a portion of the rendering engine for newer CPU instruction sets (SSE2, SSSE3, AVX2). Depending on zoom level, CPU type, and other factors, rendering throughput has been improved by 10-50%.
- Improved: Some performance optimizations for code that uses the indexers on the Surface class, which should improve effect plugin performance (thanks @Bruce Bowyer-Smyth!)
- Fixed: Shortcut keys for the Adjustments menu weren't working until after you opened the menu for the first time
- Fixed: Canvas checkerboard, used to indicate transparent regions of the image, now scales with DPI
- Fixed some of the more rare cases of the SEHException/AccessViolationException crash caused by Direct2D
- Fixed: A bug in IndirectUI was resulting in a crash when using @BoltBait's Level Horizon plugin
- Fixed: Per-user fonts no longer cause a crash for the Store version
- New: The paintdotnet: protocol now works for the Classic version
- Fixed: The paintdotnet: protocol should now work properly with paths that have spaces in them
- Fixed: Hardened security for loading Custom Shape plugins via XAML (thanks @Bruce Bowyer-Smyth!)
paint.net 4.1.4 - released on November 4th, 2018
This is a small update that fixes some important bugs and substantially improves plugin loading performance.
- Improved: Massive startup performance improvement when lots of effect plugins are installed
- Fixed a crash that would happen when closing an image, exiting the app, or sometimes just at random. This was happening due to a bug in Direct2D where ID2D1EffectContext does not honor the multithreaded initialization flag from its ID2D1Factory, and was thus corrupting its own internal data structures when released on the finalizer thread.
- Fixed: DirectX 9 GPUs can now utilize hardware acceleration again (in 4.1.3 they were forced to use software rendering)
- Fixed: The Black & White and Invert Colors adjustments no longer display an OK/Cancel dialog
paint.net 4.1.3 - released on October 24th, 2018
This is a hotfix that addresses a crash which was affecting systems with pre-DirectX 10 GPUs.
- Fixed a crash when zooming due to missing pixel shader support on DX9 class GPUs
paint.net 4.1.2 - released on October 22nd, 2018
This is a small update that improves startup performance, fixes some bugs, and addresses two security vulnerabilities.
Administrators who manage deployments of Paint.NET are urged to begin updating immediately.
Details of CVE-2018-18446 and CVE-2018-18447 are pending publication.
- Improved startup performance if "a lot" of effect plugins are installed. More optimizations are coming in the next update.
- Fixed: Pixel grid no longer draws some dots darker than others at some zoom levels, as reported at https://forums.getpaint.net/topic/112794-pixel-grid-rendering-problems-when-zooming/
- Fixed: Radial Blur was not handling alpha correctly
- Fixed: IndirectUI ColorWheel swatch is now rendered correctly (without the fading alpha gradient)
- Fixed: The tooltip describing the shortcut key for tools now indicates how many times to press the key (e.g., press S four times for Magic Wand selection)
- Fixed: Pressing Escape to deselect now works with all tools (this bug was introduced in v4.0)
- Fixed: Images with variable alpha were not displaying correctly at some zoom levels. They were "too dark" in translucent regions.
- Fixed: For the Store release, launching with the paintdotnet: protocol no longer shows an error if no parameters are provided (thanks
- Fixed a crash for some effects that were rendering too quickly
- Fixed a bug in the Image>Resize dialog where the asterisk and the note about which resampling mode was being used, e.g. "* Bicubic will be used," weren't going away or updating correctly
- New: Added a /set:SETTING=VALUE command-line parameter. This is specifically useful for disabling hardware acceleration if the app won't start or you can't reach the Settings dialog. This is also necessary for the Store release whose virtualized registry cannot be edited. To launch the Store version with hardware acceleration disabled, go to Start -> Run and type in "paintdotnet:/set:UI/EnableHardwareAcceleration=false" (without quotes) and press OK
- New: Added detection for when "Diebold Warsaw" is causing Paint.NET to crash. The error message will indicate this cause.
- Fixed: Addressed CVE-2018-18446. Credit goes to Bruce Bowyer-Smyth.

paint.net 4.1.1 - released on September 11th, 2018
This is a hotfix that fixes a few small bugs, reinstates some keyboard shortcuts, and adds 2 new languages.
- New: Ukranian translation
- New: Norwegian translation
- Fixed a bug in the IndirectUI color wheel control where it wouldn't pick up the correct value for the alpha slider
- Fixed a crash with the new Shapes that would sometimes occur because the resources file wasn't updated yet (probably due to a "you have to reboot" dialog at the end of updating that was ignored)
- Reinstated the shortcut keys for the Adjustments menu, as this was a very unpopular change
- Improved: IndirectUI angle chooser control now supports the UpDownIncrement property (thanks @toe_head2001!)
paint.net 4.1 - released on September 5th, 2018
This update converts some effects to use the GPU for rendering, resulting in huge performance gains. Copy/Paste can now be performed on selections,
Bicubic resampling is now available for the Move Selected Pixels tool, and there are lots of little quality-of-life improvements and general bug fixes.
- Improved: Gaussian Blur, Motion Blur, and Radial Blur now render using the GPU and are significantly faster
- Changed: The following effects are now rendered using the GPU: Edge Detect, Pixelate, and Relief
- Changed: The following adjustments are now rendered using the GPU: Black & White, Invert Colors
- New Effect: Distort -> Morphology (uses the GPU)
- New Effect: Render -> Turbulence (uses the GPU)
- New: Bicubic resampling is now supported for the Move Selected Pixels tool. A CPU with 6 or more cores is highly recommended if you want to make it the default mode from within Settings -> Tools.
- New: Edit -> Copy Selection. This will copy the current selection's geometry to the clipboard as JSON text.
- New: Edit -> Paste Selection. This will apply the selection from the clipboard to the current selection. All 5 selection combine modes are supported.
- Changed: The Text tool now uses Points for font size measurement. You can also elect to use the old font size metric, "Fixed (96 DPI)" via the dropdown to the right of the font size.
- Fixed: The Text tool's recentering algorithm when typing reaches the edge of the viewport should be better
- New: Added +/- buttons to the Tolerance and Hardness sliders.
- Changed: Increased max zoom level to 6400%
- New: The mouse wheel may now be used to scroll a long menu, such as when a lot of effects are installed (thanks @toe_head2001!)
- Changed: For Windows 7 SP1 users, the Platform Update from 2013 is now required (it contains Direct2D v1.1)
- Fixed: The "Finish" button wasn't working if it was in an overflow container (thanks @toe_head2001!)
- Fixed: Opening certain large images and then zooming with the mouse wheel would sometimes result in the scroll position being completely wrong
- Changed: Hiding a layer no longer auto-selects the nearest visible layer. You can re-enable this in Settings, although this setting may be removed in a future version.
- New: For the Windows Store release, the
paintdotnet: protocol can now be used to launch the app so that you can specify command-line parameters. For example, you can go to Start -> Run and type in
paintdotnet:"path to file1.png" path_to_file_2.png then both images will be opened (even if Paint.NET is already open)
- New: Added Heptagon (7-sided polygon) and Octagon (8-sided polygon) shapes
- Fixed the high-DPI inset-text scaling for the Shape selector (e.g. Pentagon with an inset "5")
- New: Palettes are now also loaded from Documents/paint.net App Files/Palettes. This folder name is not localized so that installation scripts may easily make use of it
- Fixed: View -> Pixel Grid will now correctly adjust to dynamic changes in the theme (light vs. dark)
- Fixed: The background color for the Tolerance slider has been corrected for non-dark themes
- Changed: Removed shortcut keys for all built-in Adjustments except for Invert Colors (Ctrl+Shift+I). This is being done to free up shortcut keys for other functionality.
- New: Added a shortcut key to trigger a full .NET garbage collection: Ctrl+Alt+Shift+` (tick/tilde). This should only ever be needed for troubleshooting purposes.
- New: Battery Saver Mode in Windows 10 is now respected, whether enabled manually or due to low battery. UI animations will be disabled.
- New: Long file paths (>MAX_PATH) are now supported on Windows 10, as long as the group policy setting is enabled ("Enable Win32 long paths")
- New for plugin developers: The IndirectUI Color Wheel control now supports an alpha slider. To use this, set the range (min/max values) of the Int32PropertyControl to [Int32.MinValue, Int32.MaxValue] (thanks @BoltBait!)
- New for plugin developers: there is a new FileChooser property control type for string properties (thanks @toe_head2001!)
- New for plugin developers: there is a new BinaryPixelOp.Apply(Surface, Surface, Surface, Rectangle) method overload (thanks @BoltBait!)
- Changed: The IndirectUI text control now has a vertical scroll bar when multiline mode is enabled (thanks @toe_head2001!)
- Changed: Visual C++ and OpenMP runtimes are now only loaded from the "app local" copy (never from the system directory). This fixes a number of headaches, and also works around a compatibility issue with the Surface Go
- Fixed: Crash when drag-and-dropping images onto Paint.NET when a tool was active but with uncommitted changes
- Fixed a very old and nasty crash, "InvalidOperationException: ScratchSurface already borrowed"
paint.net 4.0.21 - released on January 14th, 2018

- Fixed a rendering glitch in the Save Configuration dialog (it would "wiggle")
- Fixed: At certain brush sizes, the brush indicator on the canvas had a visual glitch in it due to a bug in Direct2D
- Fixed: Text tool buttons for Bold, Italics, Underline were not localized for a few languages
- Fixed a rare crash in the taskbar thumbnails
- Fixed: Drawing with an aliased brush and opaque color (alpha=255) sometimes resulted in non-opaque pixels due to a bug in Direct2D's ID2D1RenderTarget::FillOpacityMask
- Fixed: "Olden" effect should no longer cause crashes (it still has some rendering artifacts due to its multithreading problems, however)
paint.net 4.0.16 - released on April 16th, 2017

paint.net 4.0 - released on
June 24th, 2014
This release improves performance and memory usage with a new
rendering engine optimized for multicore CPUs and hardware
acceleration (GPU). Most tools now support "fine grained
history" and live adjustment of their properties, including the
Magic Wand and Paint Bucket. Selections are now antialiased,
which greatly improves their quality.
- System Requirements
- Windows 7 SP1 or newer is now required.
- .NET Framework 4.5 is now required, and will be installed if needed.
- A dual-core (or more!) processor is highly recommended.
- Hardware acceleration (GPU) via Direct2D is now supported.
- Please disable this in the Settings dialog if you experience visual artifacts.
- A brand new, asynchronous, fully multithreaded rendering engine allows performance to scale very well with respect to the number of CPU cores whether you have 2, 4, 6, or even 16 of them.
- The responsiveness of the user interface has been greatly improved, especially when working with large images.
- Memory usage is lower.
- Improved battery life impact due to fixing the way the floating windows manage their transparency.
- Startup performance when many plugins are installed is improved, thanks to the
Multicore JIT feature introduced in .NET 4.5.
- Selections are now antialiased, which greatly improves the quality around the edges of selected content. You can turn this on and off at any time from the toolbar.
- Everything related to selections now has much higher performance and greatly reduced CPU usage, especially if hardware acceleration (GPU) is enabled.
- The selection outline is now rendered using the "dancing ants" animation, which greatly improves the contrast between it and the image itself.
- The functionality previously provided by the Utilities, Window, and Help menus has been simplified, consolidated, and moved to the top-right corner of the main window.
- The image thumbnail list has been moved up 1 row so that it no longer intrudes into the current Tool's toolbar space. This means it will no longer "jump around" when you switch between tools. This also means that it is aligned to the top of the monitor when the main window is maximized, making it easier to click on images
- The image thumbnail list can now be reordered with drag-and-drop.
- A brand new Settings dialog makes it much easier to configure all the tool and toolbar defaults, among other things.
- The zoom slider and units selector have been moved from the toolbar to the bottom right corner of the window (into the status bar).
- Each image now shows up as its own taskbar item. This can be disabled in the Settings dialog with "Show image previews in the Windows taskbar."
- Layers can now be reordered with drag-and-drop.
- Ctrl+Click on the Move Layer Up/Down buttons will now move a layer to the top/bottom, respectively.
- Improved quality of Image -> Resize.
- Edit -> Copy Merged will copy all layers to the clipboard without having to use Image
-> Flatten first.
- Copying to the clipboard now includes the "PNG" format, which allows transparency to survive from many popular applications (e.g. Office)
- You can now use the middle mouse button to scroll/pan the image at any time (same functionality as holding down the spacebar along with clicking and dragging the mouse).
- Shift+Backspace will now fill the selection with the
secondary color (Backspace, the shortcut key for Edit -> Fill Selection, still fills with primary color as usual).
- paint.net now shows up in Windows' “Default Programs” control panel so you can configure its file type associations without reinstalling.
- EXIF rotation metadata is now applied when opening images (e.g. JPG taken with a rotated camera).
- Eleven (11) new languages, bringing the total to 21: Chinese (Simplified),
Chinese (Traditional), Czech,
Danish, Dutch, English,
Finnish, French, German, Hindi,
Hungarian, Italian, Japanese, Korean,
Polish, Portuguese (Brazilian), Portuguese (Portugal), Russian, and Spanish.
- Crash logs are now stored in %LOCALAPPDATA%\paint.net\CrashLogs (e.g. C:\Users\username\AppData\Local\paint.net\CrashLogs) instead of on the desktop.
- New effect: Photo -> Vignette.
- Improved the quality of the Photo -> Red Eye Removal effect.
- Improved UI for Layers -> Rotate/Zoom.
- Effect plugins now show up with a jigsaw puzzle icon next to them in the menus. You can hover over the effect to see information about it, including the author and location of its DLL.
- Errors while loading effect plugins are now displayed in the Settings dialog.
- Most Tools now support "fine-grained history." You may adjust the properties of what you've drawn (e.g. colors, toolbar settings) before committing to the layer (use the "Finish" button or press Enter), and each change is tracked in the history.
- Tools may now draw directly with a blending mode, configurable from the toolbar. All of the layer blending modes are supported, as well as “Overwrite.”
- Drawing tools (Pencil, Paintbrush, Eraser, Clone Stamp, Recolor) now have much smoother mouse input handling via
- Brush tools (Paintbrush, Eraser, Clone Stamp, Recolor) now have soft brushes support via a “Hardness” setting in the toolbar.
- The Move tools (Move Selected Pixels, Move Selection) have a much better UI for scaling, moving, and (especially) rotation.
- The Move tools now support moving the rotation anchor, which changes the center of rotation.
- The new Shapes tool replaces the Rectangle, Rounded Rectangle, Ellipse, and Freeform shape tools. 27 shapes are currently available. You may move, resize, and rotate a shape, as well as reconfigure any other properties from the toolbar (color, outline size, etc.) before committing it to the layer.
- Color Picker has a configurable sampling radius, and can sample from either the current layer or the whole image.
- Gradient tool now supports a new Spiral gradient type and allows configuration of the repeat mode (none, repeat, wrapped).
- Gradient tool has improved rendering quality via dithering and antialiasing. You can control both of these with the standard antialiasing toggle in the toolbar.
- Magic Wand and Paint Bucket now allow live adjustment of Tolerance and the Origin (click location) after clicking (press Enter to commit/finish).
- Magic Wand and Paint Bucket can now sample from either the current layer or the whole image.
- Paint Bucket tool now supports anti-aliasing.
- Recolor tool can now use the color of the pixel where you click as the color to be replaced. Or, as usual, it can use the secondary color.
- Text tool now supports multiple rendering modes: Smooth, Sharp (Modern), and Sharp (Classic). These correspond to DirectWrite rendering modes of Outline, ClearType Natural Symmetric, and GDI Classic, respectively.
- Text tool now supports colored fonts on Windows 8.1.
Paint.NET v3.5.11 -
released on August 17th,
The primary goal of this update is preparing for the v4.0 release: previous versions of Paint.NET will not be able to offer the v4.0 update.
Also included are some small fixes and performance improvements that have been ported over from the v4.0 codebase.
- Fixed: The Gaussian Blur effect was incorrectly calculating alpha values for non-opaque pixels.
- Improved performance of the Sharpen effect by about 25%
- Improved performance of the Median effect by about 30%
- Improved performance of the Fragment effect by about 40%
- Improved performance of the Unfocus effect by about 100%
- Reduced memory usage when many selection manipulation operations are in the history/undo stack (the undo data is now saved to disk)
- The built-in updater now supports upgrading to paint.net 4.0 (when it's available)
Paint.NET v3.5.10 -
released on October 9th,
This update fixes some broken shortcut keys for the View -> Actual Size command.
- Fixed: Ctrl+Shift+A now works again as a shortcut for
View -> Actual Size (broken in 3.5.9)
- Fixed: Ctrl+0 still works for View -> Actual Size even
if 10 or more images are open (broken in 3.5.9, it would
switch to the 10th image).
Paint.NET v3.5.9 -
released on October 1st,
This update improves the "Auto-Detect" bit-depth
feature, and fixes a few small issues.
- Improved: The "Auto-detect" bit-depth setting for PNG,
BMP, and TGA now also determines which bit-depth to use
based on which one produces the smallest file size, as well
as which ones can save the image without losing fidelity.
- Improved: You can now use Ctrl+0 as a shortcut key for
View -> Actual Size, in addition to Ctrl+Shift+A and
- Fixed: Some text in the DirectDraw Surface (DDS) Save
Configuration UI was not being loaded.
- Fixed: Some DirectDraw Surface (DDS) files authored with
other software (e.g. Unreal 2004) could not be loaded.
- Fixed: In some rare circumstances, clicking on the Save
button in the toolbar would crash.
- Fixed: The Korean translation has been added back in, with the
help of Bing machine translation to cover the few remaining
strings that were untranslated.
Paint.NET v3.5.8 -
on March 5th, 2011
This update fixes some issues with the
fault-tolerant save feature introduced in 3.5.7.
- Fixed: Saving to a folder that has been moved or renamed
will display an error instead of crashing (regression from
- Fixed: Saving to a Sharepoint site will now work
(regression from 3.5.6)
- Fixed: Saving to a file that is marked as read only will
now give an error instead of crashing (regression from
- Fixed: General reliability and correctness improvements
to fault-tolerant saving
Paint.NET v3.5.7 -
on February 20th, 2011
This update improves reliability of saving, further improves Copy/Paste functionality, and fixes some other miscellaneous bugs.
- Saving an image is now fault-tolerant. If there is an
error or crash while saving, the original file will be left
- Worked around a bug in some plugins that are incorrectly
using the built-in Gaussian Blur effect. For example,
Sharpen+. Now they won't crash.
- Fixed a bug with Edit->Paste into New Image, where the
new image would be 1 pixel too wide or tall, as reported at
- Fixed a bug with the Rectangle Select tool and Fixed
Ratio selection, which would be off by 1 pixel, as reported
- When pasting an image from Paint.NET into Paint.NET, it
will be a little smarter about where it puts the image.
Previously, if the location wasn't within the viewport, it
would be placed at the top-left corner of the viewport. Now
it will find the nearest point along the edge of the
viewport to place the image.
- The EXIF rotation ("orientation") metadata is now
discarded when opening an image, which was causing
aggravation with images that could then never be reoriented
correctly using Image->Rotate
- The EXIF metadata for JPEG thumbnail data are now
- Fixed a handful of memory leaks.
- Fixed a typo in the Italian translation. In the setup
wizard it was referring to "Pain.NET" (woops)
Paint.NET v3.5.6 - released
on November 18th, 2010
This update fixes several issues
related to copy-paste, improves performance and quality for a
few adjustments, and fixes a data loss bug.
When pasting an image, Paint.NET will be smarter
about ensuring it is placed within the area that has been
- Improved the performance and quality of the Curves and
Some minor improvements to memory usage, which
should help out a few scenarios on 32-bit systems.
- Fixed: If a JPEG was loaded that had an embedded ICC
profile, and was then saved as an 8-bit or 24-bit PNG, then
the resulting file would be corrupt (32-bit PNG worked fine
- Fixed: 16-bit TGAs no longer load with the red and blue
- Fixed: Copy-paste from a Remote Desktop session will no
longer be 'shifted' by 3 pixels.
- Fixed: Copy-paste from Internet Explorer, Firefox, or
Chrome should preserve alpha/transparency.
- Fixed: Copying from Paint.NET and pasting into Windows
Live Writer should now work.
- Fixed: Taking a full-screen screenshot with Print Screen
on a multimonitor system, where those monitors don't form a
simple rectangle, will now fill the 'gap area' with
transparent instead of black. (Example: two monitors of the
same size, one of which is rotated by 90 degrees)
- Fixed: If Paint.NET is opened without specifying an
image to open, and then the default image is modified and
saved, then Paint.NET will no longer close it upon
opening another one. This was causing data loss if that
default image had layers, and was then saved in a format
that did not support layers (anything other than .PDN).
- Fixed: Some systems were showing 'red X' thumbnails for
.PDN files in Windows Explorer, instead of the real
- Fixed: The EXIF "Creation Software" saved along with
images is no longer localized. This prevents certain
languages from seeing "Paint.NET ????? v3.5.6" in the image
Paint.NET v3.5.5 -
on April 25th, 2010
This update fixes a bug when saving 8-bit images, improves
layer composition and Gaussian Blur performance, and is now updated
to support the new .NET Framework 4.0 in some cases.
Fixed the bug where saving as 8-bit PNG/GIF/BMP wasn't
always working, usually with larger images.
- Improved the performance of the Gaussian Blur effect by
- Improved the performance of all the layer blending modes
- Improved the performance of zooming with the mouse wheel
on dual-core Intel Atom systems.
- Updated to support .NET 4.0 if no other version of .NET
- Reduced download size from 4.8MB down to 3.5MB.
- Fixed a small error in the Chinese translation.
Please note that the system requirements have
been updated. For Windows XP, you must now have
Service Pack 3 (SP3) installed; SP2 is no longer
supported. For Windows Vista, you must now have Service
Pack 1 installed.
Paint.NET v3.5.4 -
February 25th, 2010
This update fixes a few small bugs, and
improves performance of the Flatten command.
- Improved performance of the Image->Flatten command by
making it multithreaded.
- Fixed the File->Save As dialog not opening to the
- Fixed a crash with certain plugins and their use of the
File Open dialog.
- Fixed a very rare crash with the toolbar's font list.
Paint.NET v3.5.3, released on
February 7th, 2010
This update fixes a few small bugs.
- Fixed DirectDraw Surface (.dds) file format support for
CPUs which do not have SSE2 (Pentium III, Athlon XP).
- Fixed an issue with the File->Save dialog related to
file type plugins that were only written for opening
- Fixed some crashes which were supposed to be "out of
- Fixed a race condition with the New Image, Canvas Size,
and Resize dialogs. If you typed extremely fast you could
cause a crash by typing a negative number and immediately
pressing OK or Enter.
Fixed a File->Save dialog issue in Win7/Vista where it could
ask you about overwriting the wrong file.
Paint.NET v3.5.2, released on
January 4th, 2010
This update resolves some feature
disparities in the Text tool between GDI (XP) and DirectWrite
(Win7/Vista). It also improves overall performance, as well as
the correctness and quality of the Move Selected Pixels tool,
the Image->Resize function, and the Hue/Saturation adjustment.
- All font face variants (e.g., Arial vs.
Arial Narrow) are now available with the Text tool in
Win7/Vista with DirectWrite.
- Bitmap font types (e.g. Courier,
Terminal, Fixedsys) are now available with the Text tool
- Fixed some bad text kerning with the
Text tool at small font sizes when antialiasing was
- For the Image->Resize function, the
quality, correctness, and performance of Bilinear
and Bicubic sampling modes have been improved. Super
Sampling also has some performance improvement.
- Improved the rendering quality for
the Hue/Saturation adjustment. Also made a new icon for
- Fixed many subtle rendering issues
with the Move Selected Pixels tool. These were apparent
when flipping or rotating a selected area.
- Fixed: The Line/Curve tool was
applying pixel snapping to the curve nodes, which caused
lines to "bend" when using the Shift key to constrain
- Fixed some extraneous CPU usage
related to unnecessary or redundant thumbnail updates.
- Fixed a few dialogs that looked wrong
with Aero glass with Remote Desktop or Virtual PC.
- Fixed a nasty memory leak with
Flatten followed by Undo.
- Fixed some issues related to effects
that took awhile to cancel. As it turns out,
drag-and-drop was enabled at this time, which easily lead to crashes or hangs.
- Some Win7 systems could not detect
that .NET 3.5 SP1 was installed, even though it was. A
fallback detection function has been added.
- For plugin authors, the Effect class
now has a pollable IsCancelRequested property. This can
be used to improve responsiveness for expensive
OnSetRenderInfo() implementations which are otherwise
- For plugin authors, the
Surface.FitSurface() method is now optimized to use
multiple threads, which improves
Paint.NET v3.5.1, released on
November 19th, 2009
This update adds a new feature for
Windows 7 users, and fixes many small issues that have been
found since 3.5's release.
- New: For Windows 7,
added taskbar progress reporting for long running operations
(effects, adjustments, Image->Resize, save, install)
- Made some corrections to the French
- Running setup with /auto will
no longer launch Paint.NET when it's done
- Fixed an issue where Paste into
New Image would refuse an image on the clipboard, even
if regular Paste would take it
- Fixed a race condition with
Edit->Paste and Image->Resize whereby it would take up
100% CPU and take between 1 minute to 1 hour to finish
- Fixed an issues with Copy/Paste
where it would leave an extra line of transparent pixels
on the left, top, right, and/or bottom edges
- Fixed lag with the paintbrush
tool that was being seen on some systems
- Fixed some issues with the
paintbrush and eraser tool being misaligned when zoomed
- Fixed a crash that would happen
at (seemingly) random times, such as after drawing with
the paintbrush tool, on some systems
- Fixed a minor and obscure
rendering glitch with the Move Selected Pixels tool
- Fixed an issue with glass over
Remote Desktop or Windows 7 Virtual PC
- Fixed a minor glitch whereby the
"Unsaved Changes" confirmation dialog could never finish
rendering the image thumbnail if one of the Move tools
Paint.NET v3.5, released on November 6th, 2009
This release focused on improving performance reliability, reducing memory usage, upgrading to the latest .NET
Framework version, and refreshing
the user interface for Aero and glass (Windows 7 / Vista).
- New: Refreshed user interface with new icons and visual
styling. On Windows 7 and Vista, it is enhanced for Aero and
- New effect: Blurs ->
Surface Blur, by Ed Harvey
- New effect: Distort -> Dents,
by Ed Harvey
- New effect: Distort -> Crystalize, by Ed
- New: Russian translation.
Performance and memory usage have been extensively
optimized throughout the entire program.
Framework 3.5 SP1 is now required, which has many built-in
Disk space usage has been reduced by
about 12MB by using NTFS compression on installation files
related to staging (.MSI) and diagnostics (.PDB).
- Compression for .PDN
images has been improved.
- Effect dialog responsiveness has been improved.
- Images open much faster, especially on
single CPU systems.
performance on most systems will be better by about 20%.
usage has been reduced when more than one image is
quality has been greatly improved when zoomed in.
- The selection
outline is no longer animated. Instead of "dancing
ants", a context-sensitive "XOR" stipple pattern is
drawn. This has allowed for improved performance and
lowered CPU consumption (and longer battery life).
- The font
manager for the Text tool has been
completely rewritten, which fixes many problems seen with
crashes and missing fonts.
- On Windows XP, the Text tool has improved
reliability and font selection (it
uses GDI instead of GDI+).
- On Windows 7, the Text
tool will use DirectWrite (instead of GDI) which gives better performance and
greatly improved quality. On Windows Vista, you may
install DirectX 11 to enable this feature; otherwise GDI
will be used.
- The toolbar font
list has improved usability, rendering quality, and
significantly improved performance.
- The toolbar
font list no longer requires an application restart to
recognize newly installed fonts.
- When many fonts are
installed, both memory usage and startup performance
have been greatly improved.
- It is now drastically easier to move a very small
- All installation
prerequisites are now installed automatically, such as .NET
and Windows Installer.
- Updates are now downloaded in the
background, and installed after you exit the
application. In previous versions, this was a foreground
task and you could not use Paint.NET while the update was
- Added a
"Utilities" menu. Updates, Languages, and Plugin Errors have
been moved there.
- Added a "Manage Fonts" command to
the Utilities menu. This will launch the built-in Windows
font control panel.
- Clicking the middle mouse
button on an image thumbnail will now close the image.
the Unfocus effect.
- The DirectDraw Surface (.DDS)
file type now allows you to select the resampling algorithm
for auto-generated mip-maps.
- A processor that
supports SSE is now required (almost all CPUs purchased this
decade satisfy this).
- Fixed an issue with Gaussian
Blur and its treatment of alpha values.
- Fixed a
crash with the "Units" selector in the toolbar.
- Fixed a crash due to an overflow that
prevented very large images from working (64-bit only).
- Fixed many other miscellaneous glitches and crashes.
- The Korean translation has been removed.
Sadly, we were unable to find the resources to complete
Paint.NET v3.36 Released:
August 26th, 2008 -
This is mostly a servicing release to make some small
improvements and to fix a few important bugs.
- Improved: Effect rendering should be a
little faster now.
- Changed: Implemented some changes to
the "Add Noise" effect that were suggested by a forum
The canvas background color is now always #c0c0c0.
- Changed: The auto-updater should now
correctly detect .NET 3.5 and newer, which will help to save
bandwidth when Paint.NET v4.0 is released (it will require
- Fixed: Paint.NET now works on a system
that has the .NET 3.5 SP1 "Client Profile" installed.
- Fixed: When zoomed in and the
cursor is to the top-left of the image (negative
coordinates), the ruler is now highlighted in the correct
- Fixed: The effect rendering system no
longer sets the "Tag" property on the configuration dialog.
- Fixed: Some incorrectly authored
plugins would cause a crash when loading their support
details (author, copyright, etc.).
- Fixed: There was a bug in the color
wheel for IndirectUI that caused it to show the wrong values
- Fixed: There was a performance problem
for effects that used the IndirectUI color wheel control.
- Fixed: In some rare cases, Paint.NET
would crash while shutting down.
- Fixed: When using the "Fixed Ratio"
feature of the Rectangle Selection tool, it would crash if 0
was specified for both the width and height.
Paint.NET v3.35 Released:
July 7th, 2008
This releases introduces a new Posterize adjustment, a new
Intersect selection mode, dramatically improved
performance for selection editing, and several small bug fixes.
Posterize adjustment, by Ed Harvey.
- New: Intersect selection editing mode.
Improved: Dramatically improved
selection editing performance for the Add and Subtract modes
(and also for Intersect). The performance used to be
dependent on image size, and thus was often unusable on
images larger than 1024x768 pixels. It is now dependent only
on selection complexity (number of polygon edges) -- the
improvement is generally between 3x and 1000x.
- New: When holding Ctrl or Alt for a
selection tool, the cursor now has a plus or minus
- Changed: The canvas background is now a
solid color instead of a gradient. The gradient was causing
certain tone misjudgments related to bright versus dark
- Changed: Shortcut key for Sepia is now Ctrl+Shift+E. The
shortcut for Posterize is now Ctrl+Shift+P.
- Changed: Hotkeys for selection modes
are now Left click for Replace, Control+Left click for Add
(union), Alt+Left click for Subtract (difference), Ctrl+Left
click for Intersect, and Ctrl+Right click for Invert (xor).
- Changed: When using a selection mode
other than "replace", it will now draw the selection outline
so that you can see both the original and resulting
selection areas. Before, it would only draw the resulting
selection area outline, which made modes such as Intersect
hard to use.
- Fixed: The Resize dialog had some
rounding errors with the "Maintain aspect ratio" feature,
which caused a few discrepancies and even a spurious "out of
- Fixed: Some quirks with the Color Wheel
control for IndirectUI-based effect plugins.
- Fixed: Several miscellaneous and rare
- Fixed: The installer would display a
bizarre error if a "blank" install folder was attempted.
- Fixed: The installer now only accepts
absolute path locations, instead of relative ones. This
fixes an ambiguity between where Paint.NET believes it is
installing itself to, and the directory that Windows
Installer actually uses.
- Fixed: Sometimes pasting would result
in a crash when certain types of malfored data were on the
- Fixed: It was possible to get around
some of the protections imposed by the IndirectUI system.
This was causing instability with some effect plugins such
as "Fern Fractal".
- Fixed: There were some issues with the
implementation of "linked" sliders for effects
based on IndirectUI.
May 1st, 2008 -
This is mostly a servicing release to fix a few important bugs.
- New: Enabled integration
Clippings, which is a high quality screen capture
utility by Kenny Kerr.
- Fixed: Fixed a crash
with the Open/Save dialogs if the Documents or Pictures
directories were either inaccessible or if the user did not
have certain file system permissions.
- Changed / Fixed: The
hotkey for Adjustments -> Levels is now Ctrl+Shift+L instead
of Ctrl+Alt+L. This was preventing certain characters, such
as the Polish 'ł', from being typed.
April 10th, 2008
release adds an Italian translation, a new "Fragment Blur" effect,
ability to save PNG images at 8- and 24-bit color depths. For
developers, the IndirectUI system has some new controls, some
new constraint rules, and can now be used for file type plugins.
- New: Italian
- New: Ability to save
PNG's at 8- and
24-bit color depths.
- New: Ability to save
BMP's at 8-bit color depth.
- New: "Auto-detect"
bit-depth option for PNG, BMP, and TGA file types. It will
analyze the image and determine the lowest bit-depth that
can still save the image without quality loss.
- New: "Fragment" blur
effect, by Ed Harvey
- New: The "Polar
Inversion" distortion effect has been enhanced to allow
changing the rendering offset, and the behavior for "edge"
pixels (clamp, reflect, or wrap).
- New: For developers, added a Color
Wheel control to IndirectUI for use in effect plugins.
- New: For developers, added ability to
customize certain properties of the effect configuration
dialog via IndirectUI.
- New: For developers,
IndirectUI can now be used to write configuration
UI for file types.
- New: For developers,
IndirectUI has a new radio button control type for
enumerations, and some new property constraint rules.
- Changed: Most effects and adjustments,
including plugins that use IndirectUI, have been visually
refreshed. The new look is cleaner and more compact. These
changes are shown in more detail at
- Fixed: Various UI issues with the
- Fixed: When pasting text into the Text
tool with Ctrl+V, it would hide the nub for moving the text.
- Fixed: If the startup tool was set to
the Zoom or Pan (Hand) tool, then the toolbar would render
- Fixed: Thumbnails for PDN images now
include transparency, which improves their appearance in
- Fixed: In some cases, an exponential
property slider would get "stuck" at some values when using
up/down keyboard keys. This mostly affects some effect
- Fixed: When using keyboard navigation,
sometimes the File menu would scroll its items out of view.
- Fixed: Some crashes that were tracked
down to out-of-bounds coordinate values in certain effects.
- Fixed: The installer
would fail if Paint.NET had never been installed before, and
was being installed to any non-default directory. This bug
only affected version 3.22.
January 12th, 2008 -
This release fixes a few minor bugs and adds a new, much-needed
Reduce Noise effect.
- New: "Reduce Noise" effect.
- Changed: Ctrl+W will now close Paint.NET if zero images are open.
- Fixed: In Windows XP, when launching web content, sometimes Internet Explorer was used instead of the user's chosen default browser.
- Fixed: The Unfocus effect was not handling alpha values properly.
- Fixed: The Brightness / Contrast adjustment was only displaying its text in English.
- Fixed: The /auto parameter for the installer now correctly allows for an automated installation. This was
inadvertently broken in 3.20.
Paint.NET v3.20 Released: December 12th, 2007
This release adds numerous enhancements and tweaks to the
built-in effects, a re-organized Effects menu, a new and much
easier system for effect plugin development,
better error handling for plugins, and the ability to draw Fixed
Ratio and Fixed Size selections with the Rectangle Select tool.
It also includes the customary list of tweaks and fixes.
- Rectangle Select tool can now draw selections based on a
Fixed Size or Fixed Ratio setting.
- The selection combination mode is now accessible from
the toolbar (Replace, Add, Subtract, Invert ("xor")).
- The "flood mode" for the Magic Wand and Paint Bucket
tool are now accessible from the toolbar (Continuous, or
- Reorganized the Effects menu so that all effects are
classified under submenus named Artistic, Blurs, Distort,
Noise, Photo, Render, and Stylize.
- Improved rendering quality for the Motion Blur
- Enhanced the Radial Blur effect so that the center of
blurring can be chosen, as well as the quality.
- Enhanced the Zoom Blur effect so that the center of
zooming can be chosen.
- Enhanced the Bulge distortion effect so that the center
of "bulging" can be chosen.
- Enhanced the Frosted Glass distortion effect in several
ways: 1) performance has been improved from between 1,000%
to 10,000% depending on image size and property settings, 2)
the scatter radius can now be set up to 200 pixels, 3) a
"minimum" scatter radius can be chosen, 4) a smoothness
setting is now available.
- Enhanced the Tile Reflection distortion effect by adding
a Quality property.
- Enhanced the Twist distortion effect by 1) allowing
counter-clockwise twisting, 2) allowing the size of the
twisted area to be configured, 3) allowing the
location/center of twisting to be chosen.
- Enhanced the Add Noise effect by adding a "coverage"
- New Mandelbrot Fractal and Julia Fractal render effects.
- New IndirectUI system for plugin authors so that they
can develop much more sophisticated effect configuration
dialogs with a fraction of the amount of work that used to
- If an effect plugin crashes, it is much more likely that
Paint.NET will be able to recover from the error.
- The option to restart Paint.NET will then be provided as
a recommended course of action.
- If an effect plugin fails to load, or is blocked from
loading, then a "View Plugin Load Errors..." item will be
added to the File menu which can be clicked on to show the
error and/or diagnostic information.
- Improved the cursors for the Magic Wand and Paint Bucket
- Ctrl+Alt+0 now works for View->Actual Size (aka, "Zoom
to 100%"), which is a shortcut key that other software uses
- Updates are now installed faster by only creating one
System Restore point instead of two (it used to implicitly
create one for uninstall, then one for the reinstall).
- Lots of little bug fixes.
Paint.NET v3.10 Released: August 23rd, 2007
This release adds two new
effects originally written by David Issel ("BoltBait"), support for the DDS filetype originally
written by Dean Ashton, as well as many small bug fixes and some visual fit and finish.
- New: Soften Portrait effect, by
- New: Ink Sketch effect, by David
- New: DirectDraw Surface (DDS) file
format support, by Dean Ashton,
http://www.dmashton.co.uk/ . Improved from the original
source code by optimizing the DXT compression library
("Squish") to take advantage of multiple cores /
- New: "Paint.NET Search", available
from the Help menu (shortcut key is Ctrl+E), allows you to
search for Paint.NET help, forum posts, tutorials, plugins,
and other related material:
http://searchpaint.net (Note: This feature is only
available in English.)
- Improved: Visual fit-and-finish
for the Layers window.
- Improved: Visual fit-and-finish
for the close / 'X' button on image thumbnails.
- Improved: Small (about 5-10%)
performance improvements for some effects such as Oil
Painting, Frosted Glass, and Gaussian Blur.
- Improved: Increased max brush size
to 500, as per forum members request.
- Improved: Expanded list of
available font sizes up through 288.
- Changed: The keyboard shortcut key
for the Color Picker is now 'k'. This makes it so that the
toolbar option, "After click: Switch to previous tool", is
not useless for those using the keyboard shortcuts.
- Fixed: In some cases, undoing an
action that removed a layer would result in the un-removed layer not showing up until you resized the Layers window
- Fixed: Pressing F1 from the main
window no longer launches the online help in two browser tabs.
- Fixed: Adding a new layer now adds
it above the currently active layer, instead of at the very
top of the layer list.
- Fixed: Merge Down now activates
the merged layer instead of the one above it.
- Fixed: In Vista, clicking on a URL
link from the installer will no longer launch the web browser with inherited,
- Fixed: Pressing Ctrl+[ no longer
cancels out of drawing a line/curve, but instead decreases
the brush size by 5 as expected.
- Fixed: Ctrl+clicking on the brush
size +/- buttons now changes the brush size in increments of
- Fixed: Save Configuration dialog
would "creep downward" from its last position every time it
was opened again.
- Fixed: TGA codec now saves the #
of alpha bits to the image descriptor byte. This was causing
some other applications to load TGA files saved with
Paint.NET as solid black images.
- Fixed: Clicking the 'X' to close
the Layer Properties dialog was not reverting changes made
to the layer while the dialog was open.
- Fixed: Installation will not
proceed unless Paint.NET is closed, and will also not allow
Paint.NET to be opened until installation is completed. This
helps to ensure a fully coherent and complete installation
- Fixed: If a file failed to open,
and there were no open images, and the user pressed either
the Zoom In or Zoom Out toolbar buttons, then Paint.NET
- Fixed: In Vista, it was possible
to crash the Save As dialog by typing a filename that was
- Fixed: In Vista, it was possible
to crash the updater if you let the UAC prompt time-out.
- Fixed: It was possible to crash
Paint.NET on some systems by clicking on a tool in the Tools
window while the "Save As" dialog was open.
v3.08 Released: June 1st, 2007
This is mostly a service release that fixes some bugs, while
also improving keyboard / accessibility cues for some dialogs.

highlight to indicate which one will be activated if the
user presses Enter or Space.

v3.07 Released: May 8th, 2007
This update enhances the Line/Curve tool, significantly reduces
the download size, and fixes some bugs related to opening and
saving files in Windows Vista.
- New: Line/Curve tool has been enhanced to allow
drawing arrowheads, and to draw with various dashed- and
- New: Image tab thumbnails now have an indicator
if the respective image has unsaved changes (an orange
asterisk is shown).
- Improved: The Save Configuration dialog (choose
JPEG quality, etc.) now allows you to maximize it. It also
remembers its relative location and size.
- Changed: The help file / documentation is now
hosted online. This has reduced the download size by more
than 3 MB, and will also allow us to provide translations
without ballooning the size of the download (each language
would have added between 2 and 4MB).
- Changed: The "image list button" (downward
triangle) is also shown when only 1 image is open (it used
to only display if 2 or more images were open). This is
being done for the sake of consistency.

layer to the first/lowest layer. This selection is now
- Fixed: The Image->Rotate commands no longer hang
if a selection was active.
- Fixed: Several problems have been fixed within
our implementation surrounding the new Vista Open/Save
dialogs. This includes: opening an image from an http://
source, opening images from a digital camera that is not
mapped to a file system path (such as a drive letter), the
Save dialog not always prompting you about overwriting an
existing file, and many corner cases that previously caused

This major release introduces a new
multi-document interface (MDI), availability in 8 languages, a
highly-requested interactive gradient tool, four new effects, a
user-definable color palette, lower disk space usage for scratch
files, and a generally cleaner and improved user interface.
What's new in Paint.NET v3.0?
- Simple and intuitive tab-based multi-document user interface
- Now available in 8 languages: English,
Chinese (Simplified), French, German, Japanese, Korean,
Portuguese (Brazil), and Spanish
- Interactive Gradient Tool that
makes it very easy to draw and then fine-tune placement and
coloring of a gradient.

to just the color wheel)
- New effects: Clouds, Median, Unfocus,
Outline, and an improved Sharpen
- More intuitive and more powerful toolbar

Released: August 31st, 2006

- Fixed: DPI was not being saved or loaded correctly for
file types other than PDN and JPEG
- Fixed: Text Tool now works with Alt+#### special
character entry without moving the cursor
- Fixed: Loading PNG images with alpha was often resulting
in incorrect, off-by-1 color values
Released: August 2nd, 2006
This is a small interim release that includes many of the
popular effect plugins we have written that users have enjoyed
using with Paint.NET v2.6x. We have decided to release this as a
".1" update now so that more users may benefit from these
plugins, as opposed to waiting until the final release of v3.0
to include them (which could be awhile).
With this release we have also refreshed Paint.NET's system
requirements. We now list 256 MB as the minimum memory required
instead of 128 MB. This is in line with what we have seen to be
a more reasonable minimum system for using Paint.NET. Also,
Windows XP users must now have SP2 installed (SP1 was required
before), Windows 2000 users must have SP4 installed (SP3 was
required before), and Windows Server 2003 users must have SP1
installed (no SP was required before).

- New effect: Polar Inversion
- New effect: Tile Reflection
