About the HEX to CMYK Converter

The HEX to CMYK Converter turns a screen HEX color into the cyan, magenta, yellow and key (black) percentages used for print. Because screens use additive RGB and printers use subtractive CMYK inks, this conversion is the bridge between how a color looks on a monitor and how it will be reproduced on paper.

Enter any 3- or 6-digit HEX code and the tool shows the four CMYK percentages (0–100%) alongside a live swatch, with the full CMYK string copyable in one click. It uses the standard mathematical conversion, giving you a reliable starting point before you fine-tune against a printer's color profile.

Conversion happens entirely in your browser. Nothing is uploaded, no sign-up is required, and it works offline once loaded.

Frequently asked questions

What is CMYK used for?

CMYK is the color model used in most color printing. It stands for cyan, magenta, yellow and key (black) — the four ink colors that combine on paper to reproduce a full range of colors. Design files headed to a commercial printer are usually specified in CMYK.

How do you convert HEX to CMYK?

First convert the HEX to RGB and normalize each channel to a 0–1 range. Key (black) is 1 minus the largest channel. Then cyan, magenta and yellow are each computed as (1 − channel − K) / (1 − K). The results are expressed as percentages from 0 to 100.

Why do my printed colors look different from the screen?

Screens emit light (additive RGB) and cover a wider gamut than printer inks (subtractive CMYK), so some vivid screen colors simply cannot be printed and get approximated. Paper, ink and the printer's color profile all shift the result, which is why a proof or profile-based conversion matters for critical work.

Is a mathematical HEX-to-CMYK conversion accurate for printing?

It gives a solid, consistent estimate, but professional print workflows use ICC color profiles that account for a specific printer, ink and paper. Use this converter to get close, then rely on your print shop's profile and a proof for exact results.

What does the K in CMYK stand for?

K stands for key, referring to the key plate — historically the black plate that carried the fine detail in printing. Black gets its own ink because mixing full cyan, magenta and yellow produces a muddy dark brown rather than a true black.
