Which color formats are supported?
HEX, RGB/RGBA, HSL/HSLA, HSV, CMYK and OKLCH, plus CSS color names like 'tomato'. Enter any one and get all the others.
Is the CMYK value accurate for print?
It's a mathematical approximation. True print CMYK depends on an ICC profile and the press, so use it as a quick reference, not a proofing value.
What is OKLCH?
OKLCH is a modern, perceptually-uniform color space (lightness, chroma, hue) supported in current CSS — great for building even color scales.
Is my data uploaded?
No — all conversion happens locally in your browser.
