The GBR file format is associated with GIMP (GNU Image Manipulation Program), a freely distributed image editing software. It is specifically used to store custom brush designs that can be used within the GIMP software for various drawing and painting purposes. These brush files allow users to create and save their own brush patterns, shapes, and textures, enhancing their digital artwork and editing capabilities. The GBR format enables easy sharing and distribution of custom brushes within the GIMP user community.
