What is the difference between .erf and .fax?

Name: Epson RAW Format; Group 3 FAX
Extension: .erf; .fax
Format: Binary; Binary
Category: Camera; Fax
Developer: Epson; ITU-T
Description: This format was created to store images in RAW format that were created using Epson digital cameras. The image is stored in an uncompressed form, and it can be directly printed on Epson printers. This format can be edited using the Epson PhotoRAW software or using plug-ins in other image editors.; 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.
