The JBIG2 compression algorithm searches for groups of pixels arranged in similar shapes and uses 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 rate matches 100:1 compared to uncompressed black and white TIFFs.
