RGB to CMYK Converter
Type a RGB value and get CMYK straight away. Everything runs in your browser — nothing is sent to a server.
HOW
How the conversion works
Normalise each channel to 0–1, take K = 1 − max(R,G,B), then C = (1−R−K)/(1−K) and so on. This is a plain conversion without an ICC profile, so follow your printer’s reference for real jobs.
