- 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.
- Unicode Braille (uBrl) is a file format that stores information in the form of a braille code, which is a tactile writing system used by people who are blind or have low vision. The file format is used to store text in a way that can be read by a braille device or software.
