What is a FAX file?

FAX Document

Files that contain the .fax file extension are most commonly associated with digital fax files. Users had to use actual fax machine devices to send and receive faxes in the past. With newer Internet technology, users can now send faxes using their computers and an Internet connection.

When a user receives digital fax, the fax file is saved to the user's hard drive with the .fax file extension. Some faxing applications will also keep copies of a user's sent faxes with the .fax file suffix.

The FAX file format conforms to the ITU-T recommendations T.30 and T.4. FAX files are usually saved in TIFF format. When the file is opened, the user can see the actual fax image sent to them via the digital FAX software.
