7-Zip is an open-source free file archiver software ➤ Download Now

7-Zip is an open-source file archiver with a high compression ratio predominantly for the Microsoft Windows operating system.

It operates as a command line software or with a graphical user interface. It also features integration with the Windows shell environment.

Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. It compresses to zip format 2-10% better than most other zip-compatible software.

7-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license. This file archiver works on all Windows operating systems, from Windows NT to 10 (32-bit and 64-bit).

7-Zip main features:

  • High compression ratio in new 7z format with LZMA compression and LZMA2 compression
  • For ZIP and GZIP formats, the provided compression ratio is 2-10 % better than the ratio provided by PKZip and WinZip

  • Self-extracting capability for 7z format

Changes in 7-Zip 24.08 :

  • The bug in version 24.00-24.07 was fixed:
    • For creating a zip archive: The app could write extra zero bytes after the end of the archive if a file included in the archive cannot be compressed to a size smaller than the original.
  • The created zip archive is correct except for the useless zero bytes after the end of the archive.
  • When unpacking such a zip archive, the app displays a warning:
  • “WARNING: There are data after the end of archive”.
  • The bug was fixed: there was a leak of GDI objects (internal resources in Windows) in the “Confirm File Replace” window, causing problems after 1600 displays of the “Confirm File Replace” window from the same running 7-Zip process.
  • Some optimizations for displaying file icons in the app File Manager and in the “Confirm File Replace” window.
  • Some bugs were fixed.

Supported Operating Systems:

  • Windows XP, Vista, 7, 8, 8.1, 10, 11 (32-bit, 64-bit).
  • Windows Server 2003, 2008, 2012, 2016, 2019.
