The GNU Image Manipulation Program, or GIMP, is a free software picture maker.
It is often used for making logos, making photographs bigger or smaller, changing colours, making many pictures part of one picture, making pictures nicer to look at, and changing file formats.
GIMP is often used as a free software alternative for the most popular Adobe Photoshop, but it is not made to be an Adobe Photoshop clone. GIMPs mascot is named Wilber.
