Free file archiver utility, open, extract RAR TAR ZIP archives PeaZip is free file archiver utility, based on Open Source technologies of 7-Zip, p7zip, Brotli, FreeArc, PAQ, Zstandard, and PEA projects. RAR is a proprietary archive file format that helps you archive and store important files as a group. What this means is that you can compress and distribute large files as a single file provided you converted them to the RAR file format.

RAR is a popular file archiving and compression format introduced for WinRAR (Eugene Roshal, 1995), a file archiver utility released for Microsoft Windows operating systems only. RAR compression is based on Lempel-Ziv LZSS and prediction by partial matching PPMd/PPMII (Dmitry Shkarin), which provides very good compression ratio, almost comparable with 7Z format.

The format also features data recovery capabilities (if optional recovery records are used while creating the archive), and optional AES based encryption.
'RAR' acronym stands for 'Roshal ARchive', from the surname of the author.

PeaZip, freeware and open source archiver utility, can open and extract RAR files on Linux and Windows, using the Open Source code written by Igor Pavlov in 7-Zip and its POSIX port p7zip project.
Additionally, PeaZip can automatically configure itself to use WinRAR's Rar.exe to create RAR files from PeaZip's own GUI, but only if WinRAR is installed in the system, as due RarLab's licensing terms for rar format no third parts utility can distribute a rar creation tool, unless asking RarLab for licensing the format.
No alternative Open Source free RAR archiver utility (rar creator) is available: UNRAR is available as royalty-free and open source software for allowing extraction of RAR archives both on Linux and Microsoft Windows, but with the clause of not reverse engineering the code for implementing RAR compression which prevents development of royalty free rar archivers & compressors capable to create or add files to said format.

The non reverse engineering clause about the RAR compression algorithm and code apply as well for any rewritten version, so no Free Software, royalty free RAR archiver and compressor can be created under current licensing terms. In other words, no open source alternative exist to WinRar's Rar.exe

Consequently, due to RAR's license constrains, no free software can be written to be natively capable of writing RAR archives (which is required both for RAR archive creation, add / update and repairing), unless licensing clause is circumvented calling (Windows / Wine -only) WinRar's executable rar.exe itself, that requires having WinRar (shareware, free for 40 days only) downloaded and installed as a separate product.
Please note that WinRar license's time trial legal limitations apply to any part of the package (as i.e. Rar.exe) as well, even if it does not display the warning screen as the main WinRar's GUI executable.
