The latest version requires Mac OS X Lion or higher. The Unarchiver does not compress files. The corresponding command line utilities unar and lsar is free (libre) software licensed under the LGPL run on Microsoft Windows, Linux, and macOS. The Unarchiver is a small and easy to use program that can unarchive many different kinds of archive files. It will open common formats such as Zip, RAR (including v5), 7-zip, Tar, Gzip and Bzip2. It will also open many older formats, such as StuffIt, DiskDoubler, LZH, ARJ and ARC. The Unarchiver is an absolutely free macOS app that can be successfully used as a substitute for Apple's BOMArchiveHelper.app, the free built-in unarchive utility.

The Unarchiver is designed to handle many more formats than Archive Utility, and to better fit in with the design of the Finder. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. I personally find it useful for opening Japanese archives, but it should handle many other languages just as well.

It is very simple to use and install - simply copy it into your Applications folder, or whereever else you might prefer, and then set it as the default program for archive files. This can be done either from the preferences panel in the program itself, or in the Finder.

Supported file formats include Zip, Tar-GZip, Tar-BZip2, RAR, 7-zip, LhA, StuffIt and many other old and obscure formats. See the supported formats page for a more complete list of supported formats.

Download it now from the Mac App Store! The Unarchiver is completely free, and will always remain free. If you appreciate the hard work that has gone into writing it, you can use the buttons below to donate and support the developer.

Fixed

• More RAR4, RAR5 and multipart fixes mean even more weird archives could and will be extracted.

• Sometimes, upon trying to open an especially large archive, The Unarchiver would crash. That has been fixed.
• Password protected archives used to crash The Unarchiver in some cases. Well, not anymore!
