An EFX file is an electronic fax document created by the eFax online faxing service. It functions as a digital container for faxed documents, holding both formatted text and raster graphics transmitted across internet-based fax networks. EFX files were designed to replace paper faxes by allowing users to manage, view, and archive incoming and outgoing faxes directly from their desktop or mobile device.
Under the hood, EFX files rely on efficient black-and-white and grayscale compression techniques adapted from standard Group 3 and Group 4 fax encodings, keeping file sizes small for quick transmission. While EFX files can be opened using the eFax Messenger software, converting EFX documents to PDF makes them universally accessible across all modern web browsers, PDF viewers, and mobile operating systems. You can easily convert EFX files to PDF format using Zamzar.
