7-Zip review
A free, open-source archiver with broad formats, encryption, recovery tools, and cross-platform support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
7-Zip is an open-source file archiver for compressing, extracting, browsing, and managing files. It suits individuals, developers, and technical teams that need a free tool for creating archives, unpacking diverse file types, or automating archive operations from the command line. The Windows application combines a File Manager with Windows Shell integration, while the broader download set includes console versions and source-code downloads for cross-platform use.
Its format coverage is a major reason to choose it. 7-Zip creates and extracts 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM archives, then extends extraction support to formats such as RAR, ISO, DMG, VHD, VHDX, and APFS. Windows users also get Shell integration, and FAR Manager is listed as an integration. Linux and macOS support is centered on standalone console versions, making the product a better fit for command-line workflows than for users seeking the same graphical experience across every platform.
For advanced archive handling, 7-Zip includes AES-256 encryption for 7z and ZIP, self-extracting 7z archive creation, volume splitting, and documented recovery procedures for corrupted 7z archives. Its command-line tools and standalone console components add useful options for repeatable operations and specialized environments. The main boundary is format creation: several formats can be extracted but not created, and encryption is not presented as a universal option across every supported format. Choose 7-Zip for broad, no-cost archiving with technical controls; consider another tool if you need a consistent graphical application on Linux and macOS or broader archive-creation coverage.
