Within ISO/IEC JTC 1, JPEG is Working Group 1 (WG 1) of Subcommittee 29 (SC 29) and has the formal title JPEG Coding of digital representations of images, where it is one of eight working groups in SC 29.[3] In the ITU-T (formerly called the CCITT), its work falls in the domain of the ITU-T Visual Coding Experts Group (VCEG), which is Question 6 of Study Group 16.[4]

JPEG has typically held meetings three or four times annually in North America, Asia and Europe. The chairman of JPEG (termed its Convenor in ISO/IEC terminology) is Prof. Touradj Ebrahimi of École Polytechnique Fédérale de Lausanne,[3][5][6] who previously had led JPEG 2000 development within the JPEG committee[7] and also had a leading role in MPEG-4 standardization.[8]
