A multi-platform open source C library for creating, reading and writing JPEG graphic files, with a very limited support for reading and writing GIF files as well. It was originally created in 1991 by a group known as the Independent JPEG Group as a reference implementation and library for the JPEG file format and is widely used and has been forked numerous times in search for more compression or faster speeds.

Sample applications:

  • cjpeg - compress image file to JPEG image file
  • djpeg - decompress to PPM/PGM (PBMPLUS), BMP, Utah RLE, and Targa formats
  • jpegtran - lossless transcoding between different JPEG formats, lossless rotation and flipping
  • rdjpgcom - extract textual comments in JFIF files
  • wrjpgcom - insert textual comments in JFIF files
