A color bitmap image format produced by the PhotoWorks software, which is intended to be used for the distribution of graphic information. It is used for displaying information on the Internet.

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).
