About SFF files
The .SFF file extension primarily represents a M.U.G.E.N. Sprite Archive or a Structured Fax File. In the context of game development, .SFF files are used by the M.U.G.E.N. 2D fighting game engine, created by Elecbyte, to bundle character and stage sprites. Alternatively, it is a proprietary document format created by AVM FRITZ!fax to store faxes received over ISDN connections.
Both formats present severe conversion and accessibility challenges. M.U.G.E.N. sprite files are bulky, highly specialized archives containing hundreds of uncompressed 8-bit or 24-bit images. They cannot be opened by standard image viewers without dedicated modding tools like Fighter Factory. Structured Fax Files are an obsolete, proprietary raster image format that modern operating systems and web browsers completely ignore.
To make these files usable, conversion is mandatory. If you are extracting game assets for editing or web use, convert .SFF to PNG to preserve strict color palettes and transparency. For reading and archiving legacy AVM faxes, convert .SFF to PDF or TIFF. Drag and drop your file here to analyze and convert it - free, online, and without installing software.

The SFF Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SFF converter.
