Description
The uni file type is specifically associated with Brother Fax machines, which are electronic devices used for sending and receiving faxes. These files are used to store fax documents in a proprietary format developed by Brother Industries, Ltd. The uni file format is designed to optimize the storage and transmission of fax data, ensuring that documents are accurately preserved and can be easily accessed or printed when needed. Users typically encounter uni files when managing fax communications through Brother's fax equipment or associated software.
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.
