GNU Image Manipulation Program (GIMP) is a free and open-source raster graphics editor used for image retouching and editing, freehand drawing, converting between different image formats, and more. Originally created in 1995 as a semester project, it was first released publicly in 1996 and joined the GNU Project in 1997. While GIMP lacks some advanced features of Photoshop, it provides most basic photo editing tools for free and is compatible with multiple operating systems. It has a large online community that supports users.
