The best full description of JPEG is the textbook "JPEG Still Image Data Compression
Standard" by William B. Pennebaker and Joan L. Mitchell, published by Van Nostrand
Reinhold, 1993, ISBN 0-442-01272-1. Price US$59.95, 638 pp.
The book includes the complete text of the ISO JPEG standards (DIS 10918-1 and draft DIS
10918-2). This is by far the most complete exposition of JPEG in existence, and we highly
recommend it.
The JPEG standard itself is not available electronically; you must order a paper copy through
ISO or ITU. (Unless you feel a need to own a certified official copy, we recommend buying
the Pennebaker and Mitchell book instead; it's much cheaper and includes a great deal of
useful explanatory material.) In the USA, copies of the standard may be ordered from ANSI
Sales at [phone], or from Global Engineering Documents at [phone]. (ANSI
doesn't take credit card orders, but Global does.) It's not cheap: as of 1992, ANSI was
charging $95 for Part 1 and $47 for Part 2, plus 7% shipping/handling. The standard is divided
into two parts, Part 1 being the actual specification, while Part 2 covers compliance testing
methods. Part 1 is titled "Digital Compression and Coding of Continuous-tone Still Images,
Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS 10918-1, ITU-
T T.81. Part 2 is titled "Digital Compression and Coding of Continuous-tone Still Images,
Part 2: Compliance testing" and has document numbers ISO/IEC IS 10918-2, ITU-T T.83.
Some extensions to the original JPEG standard are defined in JPEG Part 3, a newer ISO
standard numbered ISO/IEC IS 10918-3 and ITU-T T.84. IJG currently does not support any
Part 3 extensions.
The JPEG standard does not specify all details of an interchangeable file format. For the
omitted details we follow the "JFIF" conventions, revision 1.02. A copy of the JFIF spec is
