PeaZip - is a free cross-platform portable program that performs the functions of an archiver, and serves as a graphical shell for other archivers. Available under the GNU GLP license.

PeaZip was compiled in Lazaruse and written in Free Paskal. At the same time, this program is distributed only on Windows and Linux, and at the same time as the installation packages (exe files), and in versions that do not change the operating system, such versions are called portable.

This archiver also supports its own .pea file format, as well as other file formats, for which it in most cases uses external programs and libraries.

The project is available on SourceForge.net from where, as of 2017, it has already been downloaded six million times, at that time the program had existed for 11 years, while the number of downloads is constantly increasing.
