Paint.NET is free image and photo editing software for computers that run Windows. It features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. An active and growing online community provides friendly help, tutorials, and plugins.

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 Microsoft Paint software that comes with Windows, it has grown into a powerful yet simple image and photo editor tool. It has been compared to other digital photo editing software packages such as Adobe® Photoshop®, Corel® Paint Shop Pro®, Microsoft Photo Editor, and The GIMP.

The programming language used to create Paint.NET is C#, with a small amount of C++ for installation and shell-integration related functionality. The source code is available under the terms of the MIT License.

Changes in aint.NET v3.5 Alpha, build 3529:
* When zoomed in, the selection outline is again "pixelated", like it was in v3.36. This allows it to correctly outline the selected area. Compared to the old version, performance is much improved; this is because the amount of computation is proportional to the complexity of the selection instead of proportional to the area of the bounding rectangle surrounding it.
* The magic wand is no longer broken (oops).
* Fixed an important internal algorithm for correctness and improved its performance. The algorithm was the polygon scan-converter (GeometryList class), and its incorrectness may have been causing many other problems.
* Fixed some issues with the Text tool related to font fallback. This was preventing certain characters from showing up and was breaking international text.
* Reduced CPU usage of the font dropdown list.
* Fixed the "This program may not have installed correctly" warning sometimes showing up after installation on Windows 7.
