Color Converter

HEX ↔ RGB ↔ HSL with a live swatch.

Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.

Pick a color or paste any HEX, RGB, or HSL value and instantly get the others, with a live swatch and one-click copy.

Frequently asked questions

What color formats are supported?

HEX (#RRGGBB and #RGB), RGB / rgb(), and HSL / hsl(). Enter any one and the other two update live, alongside a preview swatch.

Can I use this for CSS?

Yes — every value is emitted in valid CSS form (e.g. #1f6feb, rgb(31 111 235), hsl(215 84% 52%)) so you can paste it straight into a stylesheet.
