The Unarchiver for Mac

Free macOS extraction utility that opens RAR, 7Z, and dozens of legacy formats, with strong handling of non-Latin file names.

Updated July 2, 2026 · Reviewed by SoftNexi Editorial Team, Software research and documentation

Overview

The Unarchiver is an extraction-only tool for macOS, distributed through the Mac App Store. It does not create archives — it opens them, which is what most Mac users actually need.

Its strength is breadth and character-encoding handling. Archives created on Windows with non-English file names, or in older formats such as StuffIt and LZH, usually open cleanly where Finder fails.

Because it is extraction-only, it pairs well with Keka or Finder's built-in ZIP compression rather than replacing them.

Key features

  • Extracts RAR, 7Z, TAR, GZ, ZIP, and many legacy formats
  • Handles non-Latin and legacy character encodings in file names
  • Set itself as the default handler for chosen archive types
  • Option to move the archive to Trash after extraction

How to install The Unarchiver

  1. 1. Install from the App Store

    Open the Mac App Store listing from theunarchiver.com and install.

  2. 2. Choose file associations

    Launch the app and use the Archive Formats tab to select which types it should open by default.

Bundled software
None.
Privacy
The app extracts locally. Review MacPaw's privacy policy for details about the App Store listing.

Known risks

Pros and cons

Frequently asked questions

Can The Unarchiver create ZIP files?

No. Use Finder's built-in Compress command or Keka to create archives.

Does it open password-protected RAR files?

It can prompt for a password on formats that support encryption, but complex RAR5 cases may need a full archiver.
