- Description
- 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.
- An extension of the .PNG image format that uses indexed colors and supports image animations; similar to an animated .GIF file, but uses higher compression and features full alpha support (multi-level transparency).
