Paint.NET is free image editing and photo manipulation software designed to be used on computers that run Windows. It supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. 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 MS Paint software that comes with Windows, it has grown into a powerful yet simple tool for photo and image editing.
Changes:
This release fixes a few minor bugs and adds a new, much-needed Reduce Noise effect.
* New: "Reduce Noise" effect.
* Changed: Ctrl+W will now close Paint.NET if zero images are open.
* Fixed: In Windows XP, when launching web content, sometimes Internet Explorer was used instead of the user's chosen default browser.
* Fixed: Unfocus was not handling alpha values properly.
* Fixed: Brightness / Contrast adjustment was only displaying its text in English.
* Fixed: The /auto parameter for the installer now correctly allows for an automated installation. This was inadvertantly broken in 3.20.
