Many of you surely have heard of compression utilities such as WinRAR and Winzip. Well KGB archiver is yet another compression utility similar to WinZip and WinRAR but offers a high compression ratio leading to smaller file sizes. KGB Archiver uses PAQ6 and PAQ7 (in KGB v2) compression algorithms to compress and decompress user files. Bad news is that it requires a lot of hardware resources during compression and decompression; a fast processor and a lot of RAM will definitely be helpful. Even if you have a top of the line Quad Core processor and plenty of RAM, chances are that it will still take a hell lot of time, specially if you are compressing large files. On the upside it will save storage space or transmission bandwidth with the high compression ratio.

You can see performance comparisons between KGB Archiver and other leading file compression utilities in this page.


Developer Description

KGB Archiver is the compression tool with an unbelievably high compression rate. Unfortunately, in spite of its powerful compression rate, it has high hardware requirements (I recommend processor with 1,5GHz clock and 256MB of RAM as an essential minimum). One of the advantages of KGB Archiver is also AES-256 encryption which is used to encrypt the archives. This is one of the strongest encryptions known for man.


  • Supports .kgb and .zip files
  • AES-256 encryption
  • Able to create self-extracting archives
  • Unicode support (both user interface and filename)

New features in KGB Archiver 2 beta 2:

  • Explorer shell extension
  • Multilanguage support: Arabic, German, Greek, Japanese, Polish, Portuguese, Serbian, Spanish, Ukrainian - download language pack here
  • Up to 8% faster compression/decompression
  • Now SFX archives run on any Windows or under WINE on Linux
  • Lots of crashes fixed
  • and more!
