Paint.NET is image and photo manipulation software designed to be used on computers that run Windows. It supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. It started development as an undergraduate college senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it. Originally intended as a free replacement for the MS Paint software that comes with Windows, it has grown into a powerful yet simple tool for photo and image editing. The programming language used to create Paint.NET is C#, with a small amount of C++ for installation and shell-integration related functionality.
- Performance in many areas has been substantially improved, and overall memory usage has also been greatly reduced (especially when more than 1 image is open).
- The user interface has been refreshed with new icons, and visual styling has been enhanced for Aero Glass (Windows 7 / Vista only).
- Upgraded to use the latest .NET Framework 3.5 SP1, which has many built-in performance improvements.

- New effect: Distort -> Dents, by Ed Harvey
- New effect: Distort -> Crystalize, by Ed Harvey
- The font manager for the Text Tool has been completely rewritten, resulting in increased performance and better reliability. On Windows 7, the quality of text is much better as a result of using DirectWrite (this also works on Windows Vista if you have installed DirectX 11).
- The built-in updater now has the ability to download updates in the background, and will wait until you exit Paint.NET to install them. In previous versions, the download happened in the foreground, and you had to wait for the entire process to complete before you could use Paint.NET again.
- Now includes a Russian translation.
This is a small update that improves some quality-of-life issues, and fixes some important crashes due to mishandling of some non-fatal DirectX errors.
If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.
For the Classic release, you should be offered the update automatically within the next week or so. You can get the update sooner by going to Settings → Updates → Check Now. You can also download and install it directly from the website.
List of changes since 4.2.14:
- New: “Tolerance Alpha Mode” toggle button added to the toolbar for the Magic Wand, Paint Bucket, and Recolor tools. This permits switching the algorithm for color comparison between premultiplied (default) and straight. “Straight” will distinguish between transparent pixels with different color values, whereas premultiplied will see them as equivalent.
- New: Holding Ctrl while using the Color Picker tool will sample from the merged image (vs. just the current layer)
- New: The file name in the title bar will now have a prepended asterisk when it has unsaved changes
- Changed: The image close ‘X’ button can now be clicked for images that are not currently active
- Changed: In the Text tool, Ctrl+(Backspace, Delete, Arrow Keys) has been improved to work more like Microsoft Word. Thanks to @Bruce Bowyer-Smyth for the patch!
- Fixed: The Rectangle Select tool, when used to draw a constrained, fixed ratio, or fixed size selection, will now correctly clamp the rectangle to be within the canvas
- Fixed: Layers -> Move Layer Up/Down/Top/Bottom was not working for images with fewer than 3 layers
- Fixed: Edit -> Erase Selection will now fill with transparent black (#00000000) instead of transparent white (#00FFFFFF)
- Fixed: Custom Shapes will now be displayed in a consistently sorted order
- Fixed: “.pdnSave” ghost files should no longer linger when saving to the desktop. This was due to a bug in Windows and File Explorer.
- Fixed crashes due to DXGI/Direct3D “lost device” or “device removed” errors that can happen for various reasons (duck/undock, driver update, low memory, etc.)
- New: Plugins can now use the IArrayPoolService, a wrapper around .NET’s ArrayPool, to optimize their array allocations
- Updated bundled AVIF FileType Plus to v1.1.6. See the pdn-avif releases page on GitHub (https://github.com/0xC0000054/pdn-avif/releases) for more information.
