7-Zip is a ZIP and GZIP file archiver with an intuitive interface and high compression ratio. The tool converts files to its unique Z7 format, making the compression faster and easier. The manager is powered by LZMA and LZMA2 algorithms that are known for universal compression settings and big dictionary sizes. 

The tool’s scope is providing higher file density in a shorter time frame in ZIP, Z7, TAR, and BZIP formats. Also, the software supports rare file extensions like CAB, CPIO, DMG, DEB, ARJ, CHM. 

How Can 7-Zip Boost Your PC?

All 7-Zip features are laid out in the upper menu in the main toolbar. The functions are grouped in a drop-down menu. The compression and extraction can be run in a background mode that allows comfortable multitasking. 

Users can set a default path for all extracted objects or set it manually for each file. The View menu provides full destination history. If a user doesn’t recall the location of extracted files, the ‘View’ menu solves this issue by storing the records of all modifications. 

To access most often used files and folders, you can save files into Favorites. The menu allows you to display up top ten files on the main menu. The software supports a dual-panel view for a comfortable file preview. On the left part of a screen, there are all prepared files or archives while the right panel displays the end result. 

The tool utilizes open architecture, approved by a GNU LGPL license. All archives can be protected with AES-256 encryption, used by governmental organizations worldwide. Also, users can create self-extracting archives, which are, however, available only in 7Z format. 

7-Zip can be integrated with a Windows Shell menu and used as a default opener for all archive files. The software includes two interface versions: one with elaborate GIU, another one is managed via a command line. Users can use them separately or combine both interfaces, depending on the task. 

7-Zip is free and available on all Windows versions. Also, the software supports 79 languages. 

7-Zip Key Features Include:

  • Fast file compression and extraction;
  • High file density combined with a high compression ratio;
  • A unique 7Z format for faster file processing;
  • Intuitive interface with agile settings;
  • AES-256 encryption for strong data protection;
  • Supports ZIP, TAR, GZIP, XZ, BZIP2, and others. 


7-Zip is easy to use and download, with its simple but universal functionality. The tool supports dozens of file formats, providing a balanced combination of high file density and impressive compression ration. This archive manager can save both storage space and time as well as working with multiple archives simultaneously. The interface can seem outdated, however, the tool provides detailed instructions.

What's new in 19.00 version?

  • Encryption strength for 7z archives was increased: the size of random initialization vector was increased from 64-bit to 128-bit, and the pseudo-random number generator was improved.
  • Some bugs were fixed.
