The Unarchiver

The Unarchiver is a macOS utility that extracts files from a wide range of archive formats. It supports common containers such as Zip, Zipx, RAR, 7z, Tar, Gzip, Bzip2, LZMA, XZ, as and many less frequent types including CAB, MSI, NSIS, ISO, BIN, MDF, NRG, CDI, Split files, StuffIt, DiskDoubler, Compact Pro, PackIt, Cpio, Compress, ARJ, ARC and PAK. The program can handle encrypted archives, multi‑volume sets, self‑extracting executables, and disc images, and it preserves filenames written in non‑Latin scripts.

The tool is positioned for macOS users who need a free, always‑available solution for opening archives that the built‑in utility cannot process. Installation is a few clicks, and it can be set as the default handler for all supported archive extensions. No in‑app purchases are required, and the software remains free for all versions.

Its distinctive aspect is the breadth of supported formats and the ability to read foreign characters in archive names, offering functionality beyond the native macOS archive utility while staying lightweight and straightforward to use.
