CHD Converter

Shrink disc images to the compact .chd format — runs entirely in your browser, nothing is uploaded.

Disc type

.cue + .bin · .gdi · .toc · .nrg

Compression

Best balance of size and speed.

Audio tracks

Drop a disc, or click to choose files

one disc per drop — select all its files together (.cue + .bin…), or a .zip

Large discs can take a few minutes — chdman runs on your CPU and verifies each file as it's written. Powered by MAME's chdman (GPL v2).
