KGB Archiver is a file archiver and data compression utility based on the PAQ6 compression algorithm.

Written in Microsoft Visual C++ by Tomasz Pawlak, KGB Archiver is designed to achieve a very high compression ratio. As a consequence, the program is relatively memory- and CPU-intensive.

KGB Archiver is free and open-source software released under the terms of the GNU General Public License. Version 2 beta 2 is available for Microsoft Windows[1][2] and a command-line version of KGB Archiver 1.0 is available for Unix-like operating systems. KGB Archiver is one of the few applications that works with the PAQ algorithm for making its KGB files.[2] It has ten levels of compression, from very weak to maximum. However, at higher compression levels, the time required to compress a file increases significantly.[1] The official website is now offline.

System requirements[edit]

The minimum requirements for running KGB Archiver are:[1][3][4]

  • 1.5 GHz processor
  • 256 MB RAM
