HEX ↔ CMYK Converter

The HEX CMYK Converter changes colours between HEX and CMYK in both directions with a live preview. It is for designers moving between screen colours and a print-oriented CMYK approximation.

Screens use HEX while print uses CMYK, and the two do not map perfectly. Converting locally gives a quick approximation with a swatch, useful for planning rather than exact print matching.

1. Pick a colour, or type a HEX or CMYK value.
2. The other format is calculated automatically — HEX ↔ CMYK.
3. Check the preview swatch — HEX ↔ CMYK.
4. Copy the value you need — HEX ↔ CMYK.

• Getting an approximate CMYK value for a screen colour
• Planning print colours from a web palette
• Converting a CMYK spec into HEX for screen use
• Comparing how a colour shifts between models

• Treat CMYK results as a guide; confirm critical print colours with your printer’s profile.
• Expect some bright screen colours to look duller in print due to gamut limits.
• For exact print work, use values supplied or proofed by your print provider.

• Treating the CMYK result as print-accurate; screen-to-print conversion is only approximate.
• Ignoring that your printer’s colour profile affects the true output.
• Expecting vivid screen colours to reproduce exactly in CMYK, which has a smaller gamut.
