- Description
- JBIG is a lossless compression file format that was created for the fax machine; it can be used by other image file formats. The files created by JBIG format are smaller compared to G3 and G4 file formats.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
