7Z files software: create, open, extract 7-Zip archives



free 7z files extraction utility


Work with 7Z file format, compression and extraction


PeaZip provide full read / write support (create, open and extract 7z files) both for 7Z archives and XZ files, through the Open Source components from 7-Zip and p7zip projects (released under LGPL license, as PeaZip), and offers the same GUI frontend to create, browse, and extract 7Z archives under Windows and Linux operating systems.

free 7z files extractor


7Z format features high compression ratio (superior to ZIP and in some cases RAR format) using by default LZMA2 compression algorithm - optionally LZMA, PPMd, BZIP2 and Deflate are available as alternative compression algorithms - and built in strong compression based on AES256.

Compress to 7Z format

To add files / folders to a new archive or into an existing .7z file

  • Create 7z files from system file explorer

    • Context menu entry PeaZip > Add to archive, shows archive creation screen, to set compression settings, output destination, encryption (password protection), and other archiving options.

    • As alternative, context menu entry Add to .7Z, starts compression without further interaction

  • Create 7z files from PeaZip

    • Use Add button (or Add context menu entry) to show archive creation screen

    • Drag and drop files / folders from the system to a PeaZip instance; if you are browsing an existing archive you will be asked if you want to add files to current archive or create a new one

create 7z files

From archive creation screen it is also possible to apply AES256 encryption to password-protect the archive, and to split file - create multiple volumes smaller than desired maximum output size. From "Advanced" tab, it is possible to further fine-tune compression settings.
