What is a JBIG file?

Bitonal image created in the JBIG format; stores a black and white (1-bit) raster graphic using lossless compression; compresses at a higher ratio than the CCITT Group 4 algorithm; commonly used for fax transmissions.

More Information

The JBIG standard was replaced by the JBIG2 specification (.JB2 files), which compresses bi-level images more efficiently.
