Paint.NET has all the essentials, including tools to crop, rotate, and resize images, adjust colors, and create collages. It supports common image formats–JPEG, PNG, GIF, TIFF, and others–but not high-resolution RAW files. There are enough basic and intermediate effects and features to keep image-tweakers happy, including a red-eye removal tool that has seen dramatic improvements. Unlike most free image editors, Paint.NET supports layers, history, and has an actions manager. The pleasing interface boasts semitransparent windows for ease of use.
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 Microsoft Paint software that comes with Windows, it has grown into a powerful yet simple image and photo editor tool. It has been compared to other digital photo editing software packages such as Adobe® Photoshop®, Corel® Paint Shop Pro®, Microsoft Photo Editor, and The GIMP.
If you’re looking for a photo manipulation tool that offers more complexity than Microsoft Paint but doesn’t have the intimidation factor of a beast like Adobe Photoshop CS5 Extended ($699 to $999 )then Paint.net may fit the bill.Paint.net is in between very basic image manipulation applications like Microsoft Paint, and robust big guys like Photoshop. It’s not meant to stand in as a free substitute for Photoshop—Gimp aims to fill those shoes. With its layers and magic wand, it could be considered a “Photoshop Lite”—very lite. So if you need an easy-to-use photo editor that won’t bog you down in a myriad of options, Paint.net is a solid selection, if you can overlook some of the shortcomings.
