Postscript Document and Encapsulated Postscript PNM (Portable Any Map, a shorthand for ppm, pbm, and pgm format), PPM (Portable Pixel Map). Portable Network Graphic is often used for screenshots and computer graphics. The artifacts are usually most noticeable on images that have sharp edges, while less noticeable on photographs, which have many smooth gradients.

Icon Image File Format is Windows' image format for icons. Hexadecimal colors are used in order to apply colors to each cell. Each table cell represents a different pixel in the image. GIMP will save an HTML page with the image represented by an HTML table.

Other GIMP's native format includes GIMP Brush (.gbr), GIMP Animated Brush (.gih), and GIMP Pattern (.pat).īitmap is an uncompressed image format, which is the internal image format for Windows and OS/2 Graphic Subsystem. If you must exchange a XCF file, you can use the compress option, which uses either gzip (using xcf.gz/gz/xcfgz extension) or bzip2 (using xcf.bz2/bz2/xcfbz2 extension) compression. XCF images take up a lot of disk space, and are not supported by most image viewers, which is why XCF is more suitable for saving images for future editing (rather than image exchange).
GIMP's native format which will preserve all image data, including layer, the current selection, channels, transparency, paths and guides. These file formats are well known and their usage is quite widespread. But that's another lesson! Popular File Formats Of course, if you're saving for print, you'd need to ensure that your images were created at a high enough resolution. For print you'd be looking at EPS or TIFF, and maybe PSP (if you're exchanging images with a designer who has Adobe Photoshop).
