Group 4 FAX

G4 is a method to compress black and white images without losing quality. It is used for fax machines and as a one of the compression types for the TIFF format. G4 treats a picture as black dots and lines on a white page (less file size will be achieved if there are less black dots and lines).

Image JBIG 1-bit Raster

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.
