Edit PDN and more images, with layers, effects and limitless undo, using PaintNET photo editor

PaintNET is a free, easy to use and efficient image editor that supports layers, unlimited undo, special effects, and a wide variety of powerful tools. Originally intended as a free replacement for the MS Paint software that comes with Windows, it has grown into a powerful yet simple tool.

Layers allow you to compose one complete image from a stack of other images that are blended together. Every action you perform on an image is recorded in the History window. The number of actions you can store in the History Window is only limited by available disk space and memory.

The following file formats are supported: PNG, JPEG, BMP, GIF, TGA, DDS, and TIFF. The native Paint.NET image type is PDN, which preserves the layer structure. You can apply many special effects and adjustments to your image.

PaintNET supports plug-ins that add new effects, adjustments, and more file formats. It belongs to the best free photo editors you can find.
