The Unarchiver is a free[2] data decompression utility, which supports more formats than Archive Utility[3] (formerly known as BOMArchiveHelper), the built-in archive unpacker program in macOS. It can also handle filenames in various character encodings, created using operating system versions that use those character encodings.[4] The Unarchiver does not compress files.[5]


History

Open source era

The Unarchiver, version 1.1 was publicly introduced to the world in September 2006 by Finland-based MacOS software developer Dag Ågren to run on Mac OS X 10.4 Tiger.[6][7] Ågren's last public release was version 3.11.1 that was released in May 2016 for Mac OS X 10.3.9 Panther and higher[8]

The Unarchiver was free software licensed under the LGPL, up to version 3.11.1 (released 2016).[9] This version, and the versions prior to the buyout, are still available for download from Dag Ågren’s original website.[10] The Unarchiver version 3.11.1 provided a free-software implementation of extraction of RAR versions up to RAR5.[11][12]

Closed source era

Ukraine-based MacPaw purchased The Unarchiver and related software technology from Dag Ågren in July 2017 for an undisclosed sum.[13][14] MacPaw released version 4.0.0 in June 2018 for Mac OS X 10.7 Lion and higher.[15] Version 4.1.0 was released in February 2019.[16] Version 4.3.5 was released in May 2022 for Mac OS X 10.9 Mavericks.[17]

The most recent version, 4.3.9, was released in March 2025 for MacOS 10.13 High Sierra or later.[18]

unar and lsar command line utilities

The corresponding command line utilities unar and lsar are free software licensed under the LGPL[19][20] run on Microsoft Windows, Linux, and macOS.[21]

Ågren released version 1.0 of the command line utilities in March 2012.[22] Ågren's last public release was version 1.10.1, which was released in May 2016.[23] MacPaw performed minor fixes and bumped the version up to 1.10.7 by April 2020.[24]

The Archive Browser

In March 2012, Ågren released version 1.0 of The Archive Browser, a finder-like program that can browse inside almost any archive which can be opened by The Unarchiver, on the Mac App Store as a commercial program that required Mac OS X 10.6 Snow Leopard or later.[25] Ågren's last public release was version 1.11.1 that was released in May 2016 for OS X 10.7 Lion and higher[26] Although, MacPaw acquired The Archive Browser in 2017, MacPaw did not further develop this technology and eventually dropped its distribution by mid-2020.[27]

Archives

Archives is an iOS version of The Unarchiver. Version 1.0 was released in October 2012 by Dag Ågren as a commercial product.[28] Ågren's last public release was version 2.1 that was released in May 2016.[29] MacPaw performed minor fixes and released version 2.1.1 via the Mac App Store in October 2018. Version 2.1.1 is the most recent edition.[30]
