Paint.NET is an image and photo manipulation software.

Paint.NET started development at Washington State University as an undergraduate senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it. It is meant to be a free replacement for the MS Paint software that comes with all Windows operating systems.

Paint.NET has many of the powerful features that expensive commercial applications have, including the ability to use layers. We welcome any suggestions, and provide the source code for final releases under the MIT License.

Paint.Net requires the .NET Framework 2 in order to run.
