7‑Zip vs The Unarchiver
Side-by-side comparison of features, pricing, ratings, and alternatives.

7‑Zip is a free, open‑source file compression utility that supports a wide range of archive formats. It offers a high compression ratio for its native 7z format and can handle ZIP, RAR, TAR, GZIP, and many others. The program integrates with Windows Explorer for easy right‑click operations and provides a powerful command‑line interface for scripting and automation. It runs on Windows, Linux, and macOS, making it a versatile tool for developers and power users alike.
The Unarchiver is a free macOS application that extracts a wide range of archive formats beyond what Apple's built-in Archive Utility supports, including RAR, 7z, Tar, Gzip, Bzip2, CAB, and many legacy formats like StuffIt, ARJ, and LZH. It can be set as the default handler for these formats so double-clicking any supported archive just works. The app also handles archives with foreign-language filenames, encrypted and multi-volume archives, and can extract files from self-extracting Windows EXE installers. A companion iOS app called Archives brings similar extraction capability to iPhone and iPad.
