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. It will even open other kinds of files, like ISO and BIN disc images, some Windows .EXE installers. The list is actually much longer - see the program homepage for the full list.

The Unarchiver also tries to detect and correctly handle the filename encoding in the archives it opens, allowing you to open files from every part of the world without getting garbled filenames.

The Unarchiver aims to be the only unarchiving program you will ever need, and to stay out of your way.

However, if you want to browse the contents of archives, or if you want to support development of The Unarchiver, look for "The Archive Browser" on the Mac App Store, or go to! It lets you browse and preview archive contents, and find out information about archives!

Also, if you need to open archives on your iPad or iPhone, look for "Archives" on the App Store, or go to It is based on The Unarchiver, and lets you easily handle Archives on iOS!


Release Notes:

• Fixes an issue with extracting certain RAR archives. Unfortunately, it was introduced in previous version, and we are grateful to our users who helped us quickly resolve it.

OH MY GOD!!! - I almost lost a year’s worth of work!!! I”m talking about an 8 gig zip file here!!! I compressed the folder in order to save disk space (something that I”ll be very hesitant to do in the future) and when I went to unarchive it, I kept getting an "error 1- action not permitted” dialogue box. I freaked out!!! I tried other unarchivers, tried a trick in terminal and tried opening the zip in my other mac. NOTHING WORKED!!! Either the familiar ‘error 1’ box would pop up or the app would say that the file may be corrupt. Then I saw a forum where someone else had the same problem. Another user suggested The Unarchiver and the person with the original problem reported back that it had worked. Funny thing was, The Unarchiver had already been in my app folder. My jaw dropped open when it started unzipping the folder. I could tell that it was working because it started naming off the contents at the bottom of the progress bar. Thank you! Thank you! Thank you! After using a few of the other unarchivers, I really appreciate the fact that The Unarchiver actually HAS a progress bar. The other apps that I used didn’t and it was hard to tell wether they were actively trying to open my zip file or not. Once again, thank you so much!!!

Review by chinmas

Does nothing… - I’ve removed and reinstalled this app 3 times now. Whenever I try to open any archive, ZIP, RAR, 7z, anything… it hangs. The app is set to always ask me where to put the extracted file, but the dialog box never opens. The Unarchiver window opens with the filename of the archive, but it just sits there and never does anything else. I have to force quit the app for it to go away. I’ve tried reverting to an older version of Unarchiver, still not joy. I have now moved to Stuffit Expander and will not look back until these issues are sorted.

Review by AnsonX10

The only real Mac App Store essential - Every computer that I have (that supports it) has this installed on it. It is literally the easiest way to extract practically any file archive you will ever come accross. Basically the Mac equivalent of 7zip. MacPaw has provided this program (and updates) for free through the Mac App Store for years, and it has been amazing. Huge thanks to the company. Buy their software whenever you can. Their other programs are great as well.
