BMP3 (Bitmap 3) is a file format for storing and sharing digital images. It is a variant of the BMP (Bitmap) format, which is a commonly used image file format that is supported by many different operating systems and applications.
Created by JBIG (Joint Bi-level Image Experts Group), JBG is a lossless file format that contains both colored and monochrome images. Commonly used to compress fax images, and it has better compression than G3 and G4 compression codecs.
