JB2G to JP2 Conversion: FAQ

What are JB2G files?

.jb2g is the file extension for JBIG2 compression, a format that compresses black-and-white images 2–5 times smaller than CCITT G4 by identifying and reusing repeated shapes like characters across a page. It serves as the core compression engine for text layers in DjVu files.
