v24.09 | 2026-06-25 | LGPLv2.1 | 1.5 MB
7-Zip is an open-source file archiver best known for the high-compression 7z format and broad support for common archive types. It ships with a file manager, a right-click context menu, and a command-line tool, so it works for everyday archiving as well as scripted automation.
Key features
- Create and extract 7z, ZIP, TAR, GZIP, BZIP2, XZ and many other formats.
- Configurable compression levels, split volumes, checksum verification and archive encryption.
- Built-in file manager with drag-and-drop, in-place viewing and quick extraction.
- Command-line interface suitable for backup scripts and batch workflows.
Who is it for?
Anyone on Windows who regularly sends or stores files: technicians, developers, and power users. When an archive is split into parts, keep all parts together and use the correct extraction options.
Download and usage notes
Download 7-Zip from the project website and verify the signature or checksum if provided. Encrypting an archive is not a replacement for backups; test extracting a copy before deleting the original. 7-Zip is released under LGPLv2.1.
