7-Zip Portable
7-Zip Portable is the portable version of the popular open source file archiver that runs from a USB drive or folder without installation. It provides the same compression and extraction capabilities as installed 7-Zip - supporting 7z, ZIP, RAR, TAR, ISO, and dozens of other archive formats - without modifying the host system.
What it does
The portable build works identically to the installed version. You open it, navigate to archive files, and extract them - or select files to compress into 7z or ZIP format. AES-256 encryption protects archives with passwords. The 7z format compresses better than ZIP in most cases, producing smaller files at the cost of slightly slower compression.
Being portable means you carry it on a USB stick and use it on any Windows computer without admin rights. Settings and temporary files stay in the portable folder, leaving no traces on the host machine.
Advantages
- No installation - runs from USB or any folder
- Full 7-Zip functionality including encryption
- Supports virtually all archive formats
- Free and open source (LGPL)
Drawbacks
- No right-click context menu integration in portable mode
- This older distribution may be outdated

- Get the current version from PortableApps.com
Who it is for
7-Zip Portable is for anyone who needs to compress or extract files on computers where they cannot install software. Students, IT technicians, and anyone working on shared machines benefit from having a complete archiver on their USB drive. The current version is maintained at PortableApps.com.
