The most user-friendly method is using a dedicated Android application that handles the conversion without complex commands.

At its core, chdman is a compression and conversion utility originally developed for the MAME (Multiple Arcade Machine Emulator) project. Its genius lies in its ability to take raw disc images—such as those from PlayStation, Sega CD, or TurboGrafx-CD games—and compress them without losing a single byte of data. It achieves this by efficiently handling the "dummy data" often used to pad game discs and by compressing audio tracks with lossless codecs. The resulting .chd files are often 30-50% smaller than their bin/cue or iso counterparts, saving significant storage space on a device where space is at a premium.
