Color Converter (HEX, RGB, HSL)

One input, every format: paste #hex, rgb(), hsl(), or a CSS color name and get conversions, a live swatch, and a WCAG contrast check. Everything runs in your browser.

About this tool

Accepts 3-, 6-, and 8-digit hex, rgb()/rgba(), hsl()/hsla(), and the common CSS named colors, then converts between them with the standard sRGB ↔ HSL math. The contrast checker computes the real WCAG 2.1 relative-luminance ratio against white and black, so you know instantly which text color is safe on your background.

Your colors never leave the page — there is no server, no upload, and no tracking of tool inputs.
