JBIG2 PDF is a highly-compressed black and white image format that uses symbol recognition and substitution for very dramatic compression results. Any black and white image can be compressed using JBIG2 PDF including images stored as Group 4, Group 3, MO:DCA, TIFF, PDF and others.
The JBIG2 PDF compression algorithm works by searching for groups of pixels that are arranged in similar shapes and using them to define a symbol. Rather than retaining information on the placement of each pixel, a table is created for common symbols. This allows users to see incredible reductions in file sizes. Compression rates of up to 100:1 compared to uncompressed black and white TIFFs are possible.
