Paint.NET 4.3.12
A simple yet powerful and easy to use graphics editor originally intended as a free replacement for the MS Paint software that comes with Windows. It is also designed to be immediately familiar to users of MS Paint. Paint.NET supports layers and includes simple tools for drawing shapes, including an easy-to-user curve tool for drawing simple splines or Bezier curves. 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. Other effects: blurring, sharpening, red-eye removal, plus the 3D Rotate/Zoom effect that makes it very easy to add perspective and tilting.
Note: Paint.NET requires NET Framework 4.6.
