What is a JIFF file?

A JIFF file is a raster graphic saved in the JPEG Interchange File Format (JIFF). It contains image data compressed with lossy Joint Photographic Experts Group (JPEG) compression to reduce the size of the image. JIFF files often save digital photos and web graphics, similar to .JPG and .JPEG images.

JIFF and .JIF files were more common in the 1990s before improved variations of the JPEG format superseded the JIFF format. Image editors for Windows and Mac then began saving images as JPG and JPEG files, which led to the obsolescence of JIFF files.

Images saved in the JPEG format still typically use the .jpeg or .jpg file extension. However, they may also use the .jpe (.JPE files), .jfif (.JFIF files), and .jfi (.JFI files) file extensions.
