: A browser-based compressor that uses WebAssembly to run CHDMAN directly in your mobile browser without installation. It includes an optional lossy audio feature (FSLAC) to further reduce file sizes for CD games.
Besides CHDroid, a few other tools exist, though they are less complete or more experimental:

While heavy file compression is traditionally done on a PC using standard command-line tools like chdman , you can absolutely manage this process directly on your Android phone or tablet. Method 1: Using the Unofficial chdman Android Port chd converter android
Compression requires processing power and temporary storage space. Ensure your phone has at least as much free space as the size of the uncompressed game you are converting.
A standard PlayStation 1 game (e.g., Final Fantasy VII or Metal Gear Solid ) takes up roughly 650–700 MB as a BIN/CUE file. After CHD conversion, that same game often shrinks to —almost a 50% reduction. For a 512GB microSD card, this means storing 200+ games instead of 100.
Conversion is CPU-intensive. A PC can convert a PlayStation library in minutes, whereas a phone might take hours and drain the battery significantly. Why use CHD on Android? Space Saving: Reduces file sizes by 30-60% compared to standard Single File: Combines multi-track files into one single file, making your game folder much cleaner. : A browser-based compressor that uses WebAssembly to

Large ISO and BIN/CUE files take up gigabytes of precious space. Fortunately, the CHD (Compressed Hunks of Data) format solves this problem by compressing disc-based games by up to 50% without losing a single byte of data.

Various community scripts on GitHub automate the installation of chdman and maxcso for easier use on mobile.
Place all the ROMs you want to convert into a single folder (or a set of subfolders). For multi‑disc games, put all discs (e.g., Game_Disc1 and Game_Disc2 ) inside the same folder. This allows CHDroid to detect the multi‑disc nature and generate an .m3u playlist file for you.
