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:

* 3.11.1: Fixed spurious error message when extracting multi-part RAR files.
* Support for RAR version 5 archives.
* Only unpack an archive once when accidentally opening multiple parts of the same archive.
* Handle opening archives with huge number of parts better.
* Fix crash when opening certain tiny archives.
* Bug fixes for zip64, NSIS, and Squeeze.

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!!!

Version 3.9.1
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 SirBlinky87

able to select multiple files to extract in a row - Finally an extracter that i can select multiple files and press extract and they all extract with out me having to wait for each one to be extracted. It will also delete the original compressed file so i dont have to go back and find all the files ive already extracted.

Review by webpoet73

Awesome... - I rarely use any software that didn’t come with macOS if I don’t have to. But, in this case, an old ZIP file was deemed corrupted by the Archive Utility and would not unzip. I even triend PKZIP for Windows (an old friend that will “Fix” corrupt ZIP files). It was unable to save my files inside this zip file. I got Unarchiver and it did the job. All of the compressed files in my ZIP file were unzipped and are working just fine. That impressed me right there. PKZIP is a stalwart of the Windows ecosystem. I used it for years in my professional jobs and never did it fail me like it did today. I thought all hope was lost and then I used your application and it did the job. Excellent application. I don’t need or want Stuffit Expander or need to use the Archive Utility now that Unarchiver is on my machine. Two Thumbs Up!

Review by paolophonics

Yes !!! - My mac’s Archive Utility gave me an error when trying to open a ZIP file. The error was “File too LArge.” Really Archive Utility? Did you know that files are zipped because thay are large? I even tried the Terminal to unzip it. No luck. But a quick google search got me to The Unarchiver and BINGO first time worked! I love it when something actually does what it is supposed to do! (Are you paying attention Archive Utility? I’m talking to you!)
