7-Zip is a free file archiver with a high degree of data compression. Supports multiple compression algorithms and multiple data formats, including the proprietary 7z format with the highly efficient LZMA compression algorithm.

7-Zip has been in development since 1999 and is free and open source, most of which is freely distributed under the terms of the GNU Lesser General Public License, with the exception of the unRAR decompressor code, which has restrictions.

7-Zip uses multithreading and allows you to use a different number of threads for compression, depending on the algorithm or format. When creating archives in which files can be compressed independently of each other (for example, ZIP), the program can use up to 8 threads simultaneously. For the LZMA compression algorithm, the archiver can use up to 2 streams simultaneously. The impossibility of using more of them is explained by the sequential nature of continuous compression. The LZMA2 compression algorithm does not have this drawback.

When compressing in the 7z format, special normalizer filters are also used. Thus, for more optimal compression of 32-bit x86 code, normalizing converters BCJ and BCJ2 are used. 7-Zip also has an optimizing delta converter for certain types of multimedia data, such as uncompressed 24-bit images.

Compression results are highly dependent on the data being compressed. Typically 7-Zip compresses the 7z format 4-25% better than the ZIP format.

The main platform is Microsoft Windows (including Microsoft Windows CE), where two versions of the program are available: with a graphical interface and a command line version. The console version was ported by the developer community to POSIX systems under the general name p7zip. Ported versions for other systems, as well as the original 7-ZIP program, are available on the SourceForge website (as of November 7, 2010, the program has been downloaded from the site more than 109 million times).

7-Zip is the winner of the 2007 Community Choice Awards for Best Project and Best Technical Design.

The archive update function will allow you to replace or synchronize files. For security purposes, you can set a password with 256-bit archive protection using AES encryption or the ZipCrypto algorithm. There is SFX.

The free 7zip program uses powerful compression and decompression technologies, normalizing and optimizing converters and filters. The 7z implementation of the improved Lempel-Ziv-Welch (LZW) LZMA and LZMA2 algorithms allows for the highest compression rates.

The technological solutions used allow the 7zip file archiver to surpass the commercial analogues WinZip and WinRAR in compression quality. 7-Zip compresses up to 70% better in 7z than in ZIP; and in ZIP and GZIP it compresses up to 10% more than PKZip and WinZip.
