GIMP

The program is a cross‑platform image editor that runs on GNU/Linux, macOS, Windows and other operating systems. It is released as free software, allowing users to modify the source code and redistribute their changes. Its toolset covers high‑quality photo manipulation, retouching, restoration and creative compositing, as well as creation of original artwork and graphic design elements such as icons and UI mockups.

It targets graphic designers, photographers, illustrators, scientists and anyone needing advanced image processing. The application supports multiple programming languages for scripting—C, C++, Perl, Python, Scheme and others—enabling automated workflows and custom plug‑ins. It also offers color management features suitable for desktop‑publishing pipelines that often involve other free tools like Scribus and Inkscape.

Extensibility is a core aspect, with a large ecosystem of community‑contributed scripts and plug‑ins that expand functionality. The software’s stability and ongoing releases, such as the recent 3.2.4 version, reflect its mature, open‑source development model.
