KGB Archiver is an open source, free software tool designed to easily allow for the compression of files. It is a powerful, easy-to-use tool that aids in the customizable compression of a variety of files to either KBP or ZIP format. It provides 10 different levels of compression from weak to compressed, which provides functionality for different levels of compression to be used, depending on what is being archived or the data being compressed. At the highest levels of compression, the program is a bit resource intensive, but it can provide for super compressed files and data structures.

The tool is, as noted above, available for free and is designed for use with the Windows operating system. While some have noted that it can be a bit difficult to get KGB Archiver up and running the first time, it is also noted that once it is installed, the program is intuitive and easy to use. Using the AES-256 encryption for secure and quality archives and compressions, this is an innovative piece of compression software. It can even surpass the compression capabilities of the vaunted 7zip system.

The ability to choose from 10 different levels of compression provides for far more utility than most comparable software tools, making KGB Archiver one of the most powerful and advanced compression tools freely available. The software allows for security in compression, even allowing for password protection to increase the security of archives and data compressions.

The tool is not just for compression either, it also has extraction functionality, allowing the decompression of both ZIP and KGB archives.
