- Description
- The JFIF (JPEG File Interchange Format) format makes it possible to transfer compressed JPEG files across computers. This graphical file format uses a marker to show various parameters not seen in the standard JPEG file — for instance, pixel size, pixel geometry, among others.
- 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.
