About the HEX to CMYK Converter

HEX codes are how colours are passed around online — in CSS, in brand kits, in Figma and in design handoffs — but a printer needs CMYK. Moving a website’s palette onto a brochure, a business card or a banner means converting each code, and doing that by hand is slow and easy to get wrong.

Enter a HEX code, or paste a whole palette with one code per line, and each is converted to CMYK percentages. Three-digit shorthand such as #1E9 is expanded automatically and eight-digit codes with transparency are read. For the main colour you also get the RGB step in between, a swatch, contrast figures, and the colour in every other common notation.
