PeaZip is a versatile and free file archiving tool that allows users to open and extract files from formats such as RAR, TAR, and ZIP. It is compatible with various operating systems, including Linux (x86_64 and x86), Darwin, macOS (both aarch64 M1 and Intel), MS Windows, ReactOS, and Wine, with experimental support available for Linux ARM and aarch64. This utility is built on open-source technologies derived from 7-Zip/p7zip, Facebook's Zstandard fast compressor, FreeArc, Google Brotli, the PAQ family of compressors, and the secure file archiving and encryption PEA project, among other free software tools. PeaZip stands out as a cross-platform application, maintaining the same comprehensive GUI on Linux, macOS, and Windows, and also offers a portable version. Supporting more than 200 archive formats, it includes powerful compression options like 7Z and ZPAQ, as well as faster alternatives such as Brotli and Zstandard, allowing users to easily convert between different archive types. Additionally, its user-friendly interface makes it accessible for both novice and advanced users alike.
