- Description
- EFX files are associated with Everex Everfax, a type of fax document created by the Everex fax software. This file format was used for storing and sending fax documents electronically, allowing users to manage fax communications directly from their computers. The EFX format contains all the necessary information to accurately reproduce the faxed document, including text and images. Everex Systems was a prominent computer manufacturer and software company during the late 1980s and 1990s, and its Everfax product was among the early solutions integrating fax technology with personal computing.
- Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
