JBG is a lossless format used to store both black and white, and color images. It was developed by JBIG (Joint Bi-level Image Experts Group) for compressing pictures to send by fax but can also be used quite effectively on other images. Moreover, it offers better compression than the earlier G3 and G4 standards.
