GIMP is a free and open-source raster graphics editor used for image manipulation and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is not designed to be used for drawing, though some artists and creators have used it for such.
I've been using GIMP for quite some time, and it's one of the best free image editing tools available. The range of features it offers, from basic editing to advanced graphic design, rivals many paid programs. For anyone looking for a powerful, open-source alternative to commercial software, GIMP is definitely worth trying!
