- Description
- The EF3 file type is associated with Everex Everfax, a software product designed for fax communication. It specifically refers to a fax document format used by Everex's fax machines or fax software. These files contain the data of fax documents that can be sent or received using Everex technology. The EF3 format is proprietary to Everex and may require specific software to view or convert it to more common file formats.
- 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.
