Paint.Net is an excellent free image editing program for Windows. Released in 2004 as a school project the program has grown steadily over the years into an excellent mid-range image editing program supporting layers, effects, transparency and more. It’s what I use for creating documentation, basic web graphics and quick basic image editing. Perfect when Microsoft Paint isn’t enough and Photoshop is too much. Did we mention it’s free software?
