In GIMP, The file format support ranges from the common likes of JPEG (JFIF), GIF, PNG, TIFF to special use formats such as the multi-resolution and multi-color-depth Windows icon files. The architecture allows to extend GIMP’s format capabilities with a plug-in. You can find some rare format support in the GIMP registry. Thanks to the transparent virtual file system, it is possible to load and save files to from remote locations using protocols such as FTP, HTTP or even SMB (MS Windows shares) and SFTP/SSH. To save disk space, any format can be saved with an archive extension such as ZIP, GZ or BZ2 and GIMP will transparently compress the file without you needing to do any extra steps.
