- Description
- This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. Group 3 eliminates redundant data during compression in order to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can lead to a significant loss of image quality.
- Fax image created in the CCITT Group 3 compressed format, which is used for digital transmission of fax data and supports 1 bit per pixel; can be viewed by programs such as GIMP and IrfanView.
