What is a JBG file?

Image format used to store black and white, grayscale, and color images; uses lossless compression to create smaller image file sizes than other industry standard formats, such as CCITT Group 3 (G3) or CCITT Group 4 (G4) compression.

More Information

The Joint Bi-level Image Group (JBIG) format, also called JBIG1, was intended for compressing binary images, mainly for fax transmissions, but can also be used for other images. It was replaced by the JBIG2 specification (.JB2 files), which compresses bi-level images more efficiently.

NOTE: Images saved in the JBIG format also use the more common .JBIG file extension.
