You can pick up any of 8 well-known algorithms, set compression ratio to 0-9 and start the process. Unlike other programs of such a kind it can create SFX packages (*.exe files) and it will run on any other machine, no matter whether there is a version installed or not. It is integrated into Windows shell which makes it easier to use.
