StuffIt Expander is a file decompression and archive-handling utility for macOS that opens compressed files in StuffIt, RAR, ZIP, gzip, and many other archive formats. It has been a standard tool for Mac users since 1987, handling not only common compression schemes but also older Mac-specific formats like MacBinary and BinHex. The app decompresses files with a simple drag-and-drop or right-click interface. Although StuffIt Expander is no longer actively developed by Smith Micro Software (the current vendor), it remains widely used for legacy file formats and backwards compatibility. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
