ISO Compressor is a free utility designed for Windows that specializes in compressing and converting ISO image files into CSO (CISO) format. This tool is particularly beneficial for gamers who utilize Sony PlayStation or Nintendo consoles, as it allows users to reduce file sizes significantly, saving valuable disk space.
