File TypeJoint Bi-level Image Group File
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.
The JBIG standard was replaced by the JBIG2 specification (.JB2 files), which compresses bi-level images more efficiently.
NOTE: JBIG formatted images are also saved with the less common .JBG file extension.
