FXO to FLIF Conversion: FAQ

What are FXO files?

An FXO file represents the digital copy of a document that was operated through Winfax. This software program designed by Microsoft for use on Windows platforms was mostly used throughout the 90s and early 2000s for sending and receiving fax documents using a fax machine connected to a computer modem. The popularity of the program decreased together with that of fax machines in general, so now FXO files are considered obsolete.

What are FLIF files?

FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller.
