The build dated March 8, 2026 adds a Kazakh translation and refreshes the bundled DDS and JPEG XL FileType plugins.
A photo editor for Windows without a price tag
Paint.net covers the need for an editor that does more than basic drawing but stays easy to open and use. It runs on Windows PCs and is free, with a proprietary freeware licence.
The category is utilities, and the tags point to image editing, painting and photos.
Layers, unlimited undo and plugins
The store description names layers, unlimited undo, special effects and a variety of tools. Layers let you keep parts of an image separate while you work, and unlimited undo means you can step back through your edits without a set limit.
The description also mentions an active online community that offers help, tutorials and plugins. The current build bundles DDS and JPEG XL FileType plugins, which hints at the file formats it can handle.
What to check before installing the 80.3 MB package
The package is 80.3 MB, and the package ID is dotPDN.PaintDotNet. It is available for Windows only.
If you want an alternative, the catalog lists GIMP among related titles. Compare the two on your own needs before choosing.
