When do you need color conversion? CSS and HTML use HEX color codes like #1ea54c . JavaScript and canvas APIs often require rgb(30, 165, 76) . Design tools like Figma and Adobe XD export HSL values which are easier to reason about (hue, saturation, lightness).

Print workflows use CMYK . Our tool converts between all of these simultaneously — type in any format and every other field updates instantly.

HEX to HSL is one of the most searched but least-served conversions: just type your hex code and get the HSL output immediately. The color picker lets you visually choose a color and see all its representations at once.

All conversion happens client-side using the colord library — your brand colors and design palettes stay private.

Frequently asked questions

How do I convert RGB to HEX?

Type or paste the RGB value, for example rgb(255, 0, 0), into the RGB field. The HEX field immediately shows #ff0000, and the HSL, HWB, LCH, CMYK and Name fields update too. Use the copy icon next to a field to copy that value.

How do I convert a HEX color code to RGB or HSL?

Enter the HEX code in the HEX field including the # sign, for example #1ea54c. Three, four, six and eight digit codes work (the last two include transparency). The RGB and HSL fields then show the same color, ready to copy into your CSS.

Which color formats does the converter support?

HEX, RGB, HSL, HWB, LCH, CMYK and CSS color names, plus a visual color picker. Each field accepts any of these notations, so pasting red or hsl(0, 100%, 50%) into any box converts it to every other format.

Why does the Name field show a different color name?

The Name field shows the closest standard CSS color keyword. If your color is not exactly one of the named CSS colors, the nearest one is displayed, so treat the name as an approximation rather than an exact match.

Is the CMYK value accurate for printing?

The CMYK value is a simple mathematical conversion from RGB with no ICC color profile. It is a good starting point, but printed colors depend on the printer, paper and profile, so ask your print shop for profile-based values for critical brand colors.

Why do I see an invalid format message?

The text could not be read as a color. Common causes are a HEX code without the # sign, the wrong number of digits, or a missing parenthesis. Follow the placeholder in each field, such as hsl(0, 100%, 50%) or cmyk(0, 100%, 100%, 0).
