What is a FAX file?
FAX is an image file format used for scanned fax transmissions. It typically stores monochrome images in a compressed bitmap format optimized for low-resolution output on fax machines.
FAX files are part of the TIFF standard and are mostly seen in legacy document archives or digital fax software.
How to open FAX files
FAX files can be opened using graphic viewers that support TIFF subformats, including IrfanView, XnView, and some office software. You can also rename them to .tif in some cases.
To convert a FAX file to a more convenient format like PDF or JPG, just upload it to AnyConv and get your converted file in seconds.
