JPG meaning in File Type ?

The Joint Photographic Experts Group (JPEG) is the joint committee between ISO/IEC JTC 1 and ITU-T Study Group 16 (formerly CCITT) that created and maintains the JPEG, JPEG 2000, JPEG XT, JPEG XS, JPEG XL and JPEG XR digital image standards. It is one of two sub-groups of ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 1 (ISO/IEC JTC 1/SC 29/WG 1) – titled as Coding of still pictures. In the ITU-T, its work falls in the domain of the ITU-T Visual Coding Experts Group (VCEG). ISO/IEC JTC1 SC29 Working Group 1 (working together with ITU-T Study Group 16 – SG16 and previously also with Study Group 8 – SG8) is responsible for the JPEG and JBIG standards. The scope of the organization includes the work of both the Joint Photographic Experts Group and Joint Bi-level Image Experts Group.

In April 1983, ISO started to work to add photo quality graphics to text terminals. In the mid-1980s, both CCITT (now ITU-T) and ISO had standardization groups for image coding: CCITT Study Group VIII (SG8) – Telematic Services and ISO TC97 SC2 WG8 – Coding of Audio and Picture Information. They were historically targeted on image communication. In 1986, it was decided to create the Joint (CCITT/ISO) Photographic Expert Group. The JPEG committee was created in 1986. In 1988, it was decided to create the Joint (CCITT/ISO) Bi-level Image Group (JBIG). The group typically meets three times annually in North America, Asia and Europe. The group often meets jointly with the JBIG committee. The current JPEG president is Touradj Ebrahimi, who was previously chairman of the JPEG 2000 development group and led the MPEG-4 standards committee.
