What is a color converter?
This tool converts colors between HEX, RGB, HSL, and CMYK instantly, with a live preview swatch and a color picker. Type a color in any of the three input formats, drag the RGB sliders, or use the picker - every format updates together.
How to use this tool
- 1Type a color value in HEX, RGB, or HSL format, or click the color swatch to open a picker.
- 2Fine-tune with the individual Red/Green/Blue sliders if needed.
- 3All four formats (HEX, RGB, HSL, CMYK) update live - copy whichever one you need.
Common use cases

Getting the CMYK values of a brand color for print materials
Fine-tuning a color visually with sliders while watching the exact values change
Quickly checking what a color code from a screenshot or style guide actually looks like

Frequently asked questions
Why do HEX values sometimes shift by 1 after converting through HSL?
HSL stores hue, saturation, and lightness as rounded whole-number percentages, so converting RGB → HSL → RGB can introduce a tiny rounding difference (like 255 becoming 254). This is normal behavior in every color tool that supports HSL, not a bug.
What color input formats are recognized?
HEX (#RRGGBB or #RGB), rgb()/rgba(), and hsl()/hsla() - paste any of these directly into the text field and it will be parsed automatically.
Does CMYK conversion account for printer color profiles?
No - this uses the standard mathematical RGB-to-CMYK conversion, not a specific printer's ICC color profile, so treat CMYK values as an approximation for print rather than a color-managed exact match.
Is my color data sent anywhere?
No - all conversion happens locally in your browser.
