Joint Bi-level Image Group (.jbg)

The JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
