The Unarchiver

OPEN WEBSITE

The Unarchiver was originally designed to supersede the Mac Archive Utility with a better UI and support for more compression algorithms, which it did achieve. It is a free compression and decompression program for macOS, and many users now use it as the default tool for handling archives and compressed data.
