Why this tool stays in the browser

Convert between HEX, RGB, HSL, and OKLCH without uploading a palette or hitting a design-cloud API. The converter is for engineers who keep tokens in CSS and Tailwind and need round-trips that stay on-device. Check contrast separately with the color-blindness simulator, or jump to the palette generator when you need a scale rather than a single value.

FAQ

Which color spaces are supported?

Is my palette uploaded?
No. Conversion is in the browser. Use the palette generator when you need a scale, not a single swatch.
How do I check accessibility?
Use the color-blindness simulator in this sandbox after you have a HEX/OKLCH value.
