The first release supported Unix systems, such as Linux, SGI IRIX and HP-UX. The application subsequently formed part of the GNU software collection. In the following year, Kimball and Mattis met with Richard Stallman of the GNU Project while he visited UC Berkeley and asked if they could change General in the application's name to GNU (the name of the operating system created by Stallman), and Stallman approved. The community began developing tutorials, artwork and shared better work-flows and techniques. The editor was quickly adopted and a community of contributors formed. In 1996 was the initial public release of GIMP (0.54).

The acronym was coined first, with the letter G being added to -IMP as a reference to 'the gimp' in the scene from the 1994 Pulp Fiction film. In 1995, Spencer Kimball and Peter Mattis began developing GIMP – originally named General Image Manipulation Program – as a semester-long project at the University of California, Berkeley for the eXperimental Computing Facility.

GIMP is released under GPL-3.0-or-later license and is available for Linux, macOS, and Microsoft Windows. It is not designed to be used for drawing.
