Gimp
From Leechfinger
GIMP, or GNU Image Manipulation Program, is a free, open-source program that allows users to edit raster graphics. It's available for many operating systems, including macOS, Windows, and GNU/Linux. GIMP is often used by web and graphic designers to create logos, animations, user interface mockups, and web designs. Photographers also use GIMP to retouch, crop, and adjust color and lighting.
