paint.NET is free image editing and photo manipulation software for Windows. It features an intuitive and innovative user interface. Supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools.
paint.NET started development as an undergraduate college senior design project mentored by Microsoft. Originally intended as a free replacement for the MS Paint software, it has grown into a powerful yet simple tool for photo and image editing.
An active and growing online community provides friendly help, tutorials, and plugins.
Compare Paint.NET to other digital photo editing software packages. Such as Photoshop, Corel Paint Shop Pro, Microsoft Photo Editor, and The GIMP.
You can use the Paint.NET to enhance and clean up your photographs. Using the Clone Stamp tool, you can carefully remove the power lines that criss-crossed in front of the Space Needle. Every feature and user interface element are immediately intuitive and quickly learnable without assistance.
paint.NET includes simple tools for drawing shapes, including an easy-to-use curve tool for drawing splines or Bezier curves. The Gradient tool, has been cited as a huge improvement over similar tools provided by other software. The facilities for creating and working with selections is powerful, yet still simple enough to be picked up quickly. Other powerful tools include the Magic Wand for selecting regions of similar color,. And the Clone Stamp for copying or erasing portions of an image. There is also a simple text editor, a tool for zooming, and a Recolor tool.
Everybody makes mistakes, and everybody changes their mind. To accommodate this, every action you perform on an image is recorded in the History window and may be undone. Once you’ve undone an action, you can also redo it.
paint.NET has effects such as blurring, sharpening, red-eye removal, distortion, noise, and embossing. Also included is unique 3D Rotate, Zoom effect that makes it very easy to add perspective and tilting. The app also has included Adjustments. They help you tweak an image’s brightness, contrast, hue, saturation, curves, and levels. You can also convert an image to black and white, or sepia-toned.
- Fixed the app being completely broken when “Translucent windows” was disabled. This was caused by a bug introduced in .NET 6.0.1.
Changes in paint.net 4.3.6:
- Fixed a stack overflow in the box filter rendering kernel that could cause hangs or crashes when the zoom level was around 1/8th (12.5%) or 1/32nd (3.125%) for particular image sizes e.g. ((N x 2048) + 16)).
Changes in paint.net 4.3.5:
- Improved rendering performance for most tools, which are now up to 100% faster
- Fixed an issue with the Save Configuration dialog where the OK and Cancel buttons were overlapping on Windows 7
- Fixed an issue when saving an image with 257 unique colors at 8-bit color depth when the 257th unique color was the last (bottom-right) pixel.
- Fixed an issue where the Layers window buttons were not correctly enabling/disabling after an undo/redo operation.
- Fixed an issue that was preventing the VTF Plugin from saving multi-layer images correctly, as reported at
- Fixed an issue when saving images at 1-bit or 2-bit color depth, where sometimes not all colors would be included.
- Fixed an issue with some IndirectUI plugins that were using customized colors for their sliders
- Fixed a compatibility issue with TR’s Morpher plugin
- Fixed a compatibility issue with some of @Ego Eram Reputo’s older plugins that were unable to launch help links due to a change in .NET 6
Changes in paint.net 4.3.4:
- Fixed compatibility with the Spaced Text plugin, which was crashing
- Fixed a bug with the Color Picker tool, which was sampling from a recently hidden layer when using Image sampling mode
- Fixed the ability to click URLs in some older plugins (CustomBrushesMini, Shape Maker, Vandermotten Effects, and those based on OptionBasedLibrary)
- Fixed the incorrect registration of the app in the HKCR\Applications registry key, which was affecting some methods for launching the app
- Fixed many translations which had updates but that had inadvertently not been incorporated into the app itself
- Fixed the PROGRAMSGROUP property in the MSI (it was being ignored), which affects custom deployments
- Fixed the CHECKFORUPDATES property which was missing from the MSI. It still worked, but you had to add it yourself. This only affected MSI-based deployment.
Changes in paint.net 4.3.3:
- New: The app has been migrated to .NET 6, which has improved both rendering and startup performance
- New translation: Catalan (ca)
- New translation: Corsican (co)
- New translation: Thai (th)
- Changed: The /createMsi command for the installer has been removed. Instead, you can now download MSIs directly from the GitHub releases page.
- Improved various UI controls for Dark Theme, e.g. scrollbars (Win10 v1809+ only)
- Fixed the way various UI controls look on Windows 11, e.g. buttons and drop-down lists
- Fixed the View -> Zoom to Window command when using the keyboard shortcut (Ctrl+B), which was resetting instead of toggling the zoom level
- Improved performance during the “extracting” stage of the installer by migrating away from Nullsoft Scriptable Installer System (NSIS)
- Reduced the download size on ARM64 by about 33%
- Fixed a rendering bug in the Dents and Polar Inversion effects
- Fixed a memory leak in the selection renderer that was consuming gigabytes of GPU memory, resulting in crashes.
- Fixed some GDI object leaks, particularly with the Save Configuration dialog, which would eventually result in a crash.
- Fixed a memory leak in Settings -> Tools. Thanks @otuncelli for finding this!
- Fixed an issue that was preventing new plugins from loading their native DLL dependencies as specified in their .deps.json file
- Fixed the app crashing after an effect plugin crashes when you choose to restart the app
- Fixed a crash while drawing a selection, right-clicking on the History window before releasing the left mouse button, and then clicking to redo a history entry
- Fixed a text rendering bug in some parts of the UI, mostly in Effects
- Fixed the “untitled:” file name argument prefix, which was preventing Window Clippings from being able to send screenshot
- Fixed some registry keys that were not being deleted during uninstall
- Fixed the PdnRepair utility on Windows 7
- Fixed some inconsistencies with the MSI as compared to v4.2.16 which were causing problems for some deployments
- Updated the bundled AvifFileType to v18.104.22.168, courtesy of @null54, which updates the AOM version and fixes a crash when reading large EXIF blocks.
Changes in paint.net 4.3.2:
- Fixed a hang at app startup on systems using certain locales, such as Thai (th-TH)
- Improved performance of Settings → Tools, which used to take 6-7 seconds to open. Now it takes about 1 second, thanks to @Bruce Bowyer-Smyth
- Fixed ReadOnlyBoundToNameValuesRule for IndirectUI-based plugins. It was not initializing correctly, although it would work correctly afterward.
Changes in paint.net 4.3.1:
- Fixed an issue with using Explorer’s “Open With” menu on Windows 7, 8.1, and some editions of Windows 10
- Fixed image thumbnails in Explorer’s Details View only having a generic document icon instead of the Paint.NET icon
- Fixed a spurious, harmless error in Settings → Plugin Errors
- Fixed a race condition that could cause a crash
- Fixed not being able to use Ctrl+C to copy text from the Setup Downloader, which is especially important for troubleshooting
Changes in paint.net 4.3:
- New: The app has been migrated to .NET 5, and performance has been greatly improved as a result.
- New: ARM64 is now natively supported, which improves performance on devices such as the Surface Pro X.
- New: .NET no longer needs to be installed on the system because the app now uses self-contained deployment.
- New: Portable ZIPs are now available. Please note that portable installations do not currently update automatically.
- Improved performance of most effects and other compute-intensive tasks by about 20% on average, due to .NET 5’s improved code generation (JIT).
- Improved startup performance for the Microsoft Store release. Previously, .NET Framework’s NGEN was unavailable for Store apps, but now .NET 5 enables self-contained deployment along with ReadyToRun + crossgen, which serves the same purpose.
- Improved performance: Many areas of the app have been optimized to use SIMD (SSE2/3/4.1, AVX2) on x86/x64:
- Drawing on an image with a large number of layers is faster
- Drawing with the Gradient Tool’s alpha mode is faster
- Drawing with the Recolor tool is faster
- Drawing with the Eraser or Clone Stamp tool is faster when using a color whose alpha value is less than 255
- Drawing with the Overwrite blend mode is faster
- Drawing with the Shapes tool is faster, due to improved compositing performance
- Drawing with a brush tool without antialiasing is faster
- Tile compression has lower overhead due to being optimized for SSE2 and AVX2
- Working with complex selections is faster
- Many other optimizations all throughout the application and rendering engine
- Improved performance of loading custom Shapes by ~16x on 2nd and subsequent app starts.
- Improved performance of the Magic Wand tool by a substantial amount.
- Improved performance of the Paint Bucket tool by a substantial amount.
- Improved performance of the Paint Bucket when changing the color or certain other toolbar settings by not recalculating the stencil buffer for the filled area. Changes should now be visible immediately.
- Improved performance of Polar Inversion by 3x, mostly as a corollary to fixing a bug that was causing hangs, and a little bit due to .NET 5.
- Improved performanceon systems without HyperThreading by reserving 1 core for the UI. Performance is also improved on systems with it by utilizing more of the logical cores.
- Improved performance while installing or updating the app, due to no longer needing the “Optimizing performance for your system” stage (NGEN has been replaced with ReadyToRun via crossgen).
- Improved memory usage when custom shapes are installed so they don’t litter the heap with hundreds of thousands of boxed value types (e.g. floats and points).
- Improved selection antialiasing quality by using a 4×4 super sampling filter instead of a 3×3 super sampling filter. The code has also been optimized to use SSSE3 on x86/x64.
- Improved: Effect and File Type plugins can now be organized into folders. The plugin loader will recursively search for DLLs up to 1 folder deep.
- Fixed a bug when saving with “Auto Detect” bit-depth which was causing fidelity loss on some images that already had 256 colors or less.
- Fixed: There were some issues with zooming in/out using the keyboard, where the anchoring point was not calculated correctly, causing the canvas to drift in the wrong direction.
- Fixed the inability to use middle-mouse panning after using a selection tool and pressing delete before releasing the mouse button.
- Improved: Plugins are now loaded into isolated AssemblyLoadContexts, which improves stability and resiliency to various problems with versioning, loading dependencies, plugin bugs, and incorrect plugin installation.
- Fixed a crash when trying to draw a fixed-size rectangle selection that was larger than the image.
- Fixed a bug with the Tolerance slider where both 58% and 59% would be displayed as 58%, due to a rounding issue. The correct value was actually being used, it just wasn’t being displayed correctly.
- Added a /disablePlugins command-line argument to aid in troubleshooting various issues with app startup and incorrect plugin installation.
- New: Additional directories can now be specified for plugin discovery, which (e.g.) enables the use of OneDrive for storing plugins.
- Note that this does not work with the portable version of the app, but you can install plugins next to the app so it isn’t necessary.
- Updated the bundled AvifFileType plugin to v22.214.171.124, which includes support for multi-layer AVIF files, and adds native support for ARM64.
- Updated the bundled DdsFileTypePlus plugin to v126.96.36.199, which adds native support for ARM64.
- Updated the bundled WebPFileType plugin to v188.8.131.52, which adds native support for ARM64.
- Changed: FileType.IsReflexive() is now deprecated via [Obsolete], and is no longer honored. However, the Save Configuration dialog will no longer try to generate previews for FileTypes that do not specify any file extensions for loading, which is what this method was being used for.
- Known Issue: Due to crashing, GPU accelerated effects (Gaussian Blur, Motion Blur, Radial Blur) on ARM64 will actually use the CPU for rendering.
