LZMA uses an LZ-based sliding dictionary of up to 3840 MB in size, backed by a range coder. Developed by Pavlov, LZMA is a relatively new system, making its debut as part of the 7z format. The core 7z compression uses a variety of algorithms, the most common of which are bzip2, PPMd, LZMA2, and LZMA. These can consist of pre-processors, compression algorithms, and encryption filters.

Since version 21.01 alpha, preliminary Linux support has been added to the upstream instead of the p7zip project.

The program can be used from a Windows graphical user interface that also features shell integration, from a Windows command-line interface as the command 7za or 7za.exe, and from POSIX systems as p7zip. 7-Zip has its own archive format called 7z, but can read and write several others. It is developed by Igor Pavlov and was first released in 1999.
