Paint.NET is jointly developed at Washington State University with additional help from Microsoft, and is meant to be a free replacement for the MS Paint software that comes with all Windows operating systems.Paint.NET is a photo editor and manipulation software.

Download notes: Alternatively you can download the latest stable version of this software.

The programming language used to create Paint.NET is C#, with GDI+ extensions.

Paint.NET has many of the powerful features that expensive commercial applications have, including the ability to use layers.

This is the second semester that Paint.NET has been a project at Washington State University, and we have the goal of adding as much functionality as expensive commercial applications provide, but of course, for free.

In the spirit of all this freedom, we welcome any suggestions, as well as provide the source code free of charge for anyone who wishes to tinker with it.

What's New:

  • New: Added a 'Fill' property to the Paintbrush tool
  • Faster: Move Selected Pixels has been significantly optimized.
  • Faster: Magic Wand Tool has been significantly optimized.
  • Faster: Working with aliased selections ("aliased selection quality" in the toolbar) has been significantly optimized.
  • Faster: Edit->Copy and Edit->Copy Merged are now up to 2x faster.
  • Faster: Drawing when a selection is active; clipping performance is now improved.
  • Fixed: The Text tool no longer produces terrible looking text when using Smooth rendering mode without antialiasing.
  • Fixed: The Gear shape had a few glitches.
  • Fixed: Using a Fill pattern w/ the Paint Bucket would sometimes produces misaligned or "corrupt looking" results.
  • Fixed: The alignment of the menu buttons in the top-right was off by 2 pixels, causing them to look weird at high-DPI.
  • Fixed: The zoom buttons in the status bar would not recognize clicks unless the main window was already in focus.
  • Fixed: Some incorrect errors about requiring Windows 7 SP1 when launching the installer from something like an old version of WinZip.
  • Fixed: Edit->Clear Selection and Edit->Cut were filling with transparent black (#00000000) instead of transparent white (#00FFFFFF). This caused some discrepancies compared to older versions of Paint.NET.
  • Fixed: Pressing Ctrl+A when a drawing tool was active would sometimes incorrectly show a tinted selection.
  • Fixed: Text in the title bar was not visible when using a 3rd party Aero theme with black titlebars.
