The Unarchiver is a proprietary freeware[2] data decompression utility, which supports more formats than Archive Utility[3] (formerly known as BOMArchiveHelper), the built-in archive unpacker program in macOS. It can also handle filenames in various character encodings, created using operating system versions that use those character encodings.[4] The latest version requires Mac OS X Lion or higher. The Unarchiver does not compress files.[5]

The corresponding command line utilities unar and lsar run on Microsoft Windows, Linux, and macOS.[6]
