The TIFF-FX (TIFF for Fax eXtended) specification defines a family of TIFF profiles (subformats) intended for use with internet fax systems. Notably, it defines TIFF compression types 9 (T.85 JBIG) and 10 (T.43 JBIG), and photometric interpretation type 10 (T.42 ITU L*a*b*). An "extensions" document defines compression type 34715 (JBIG2).

TIFF-FX is apparently sometimes called TIFX. It was developed in part by Xerox, and may also be known by names similar to Xerox Internet Fax File Format.
