FTF to STL Conversion: FAQ

What are FTF files?

FTF represents a faxable version of TIFF (Tagged Image File Format) — a popular format offering high image quality and multi-page options. TIFF images are particularly used for storing and transferring raster graphics by amateurs and professionals in the desktop publishing industry, photography and image design. An FTF file is most likely a black-and-white copy of a TIFF image, created precisely for being sent or received through fax.
