- Description
- A CFF file is a bare Compact Font Format font program, the compact form of an Adobe PostScript Type 1 or CID-keyed font that uses Type 2 charstrings. It is the same data an OpenType font stores in its 'CFF ' table, without the surrounding OpenType wrapper, so it is usually extracted from or embedded into OTF fonts and PDF files.
- 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.
