Overview

The JBIG2 standard has been developed by the Joint Bi-level Experts Group (JBIG) for the efficient lossless and lossy compression of bilevel (black and white) images. It is capable of compressing black and white documents cosiderably more than the more commonly used CCIT Group 4 TIFF compression.

The use of symbol dictionaries and symbol matching in JBIG2 enables very effective encoding of documents containing recurring symbols, making JBIG2 ideal for compressing documents. JBIG2 has been made popular by Adobe's PDF, which incorporates JBIG2 in the PDF 1.5 specification.
