- Description
- A CMX 3 file is a vector drawing exported by CorelDRAW 2017 or later, in a newer binary layout than the classic RIFF-based CMX exchange format.
- 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.
