Why Convert ISO to GZ file?

GZ is a compressed format created with gzip, common on Linux, while ISO is a disc image. Converting ISO to GZ compresses the disc image into a gzip archive, useful when you want to shrink a large ISO for storage or transfer, or when a system expects a gzip-compressed file.

This is aimed at Linux and technical workflows rather than everyday use. Because disc images can be large, gzip compression can meaningfully shrink them, and decompressing restores the original ISO exactly, ready to burn or mount. For broad compatibility a ZIP is more universal, but for compressing an ISO on Unix-like systems, gzip is a natural choice, and this conversion applies it.
