    • Part 1 - The basic JPEG standard, which defines many options and alternatives for the coding of still images of photographic quality
    • Part 2 - which sets rules and checks for making sure software conforms to Part 1
    • Part 3 - set up to add a set of extensions to improve the standard, including the SPIFF file format
    • Part 4 - defines methods for registering some of the parameters used to extend JPEG
  • ISO/IEC IS 11544 | ITU-T Recommendation T.82 - JBIG

    • Part 7 has been abandoned
    • Part 8, JPSEC (security aspects)
    • Part 9, JPIP (interactive protocols and API)
    • Part 10, JP3D (volumetric imaging)
    • Part 11, JPWL (wireless applications)
