Color Converter

Split the 6-digit hex code into three pairs and convert each pair from hexadecimal to decimal. For example, #FF5733 becomes R:255, G:87, B:51. This converter does it instantly.

Yes. HEX↔RGB is lossless by definition. RGB↔HSL uses the standard algorithm from the CSS Color Module specification. CMYK is computed via the simple K-first reduction — note that CMYK is device-dependent in print workflows, so the values here are a nominal mathematical conversion rather than an ICC-profile-aware color-managed result. For on-screen design work, all conversions are exact.

Yes. The color picker, HEX/RGB/HSL/CMYK input fields, sliders, and contrast-ratio badges all adapt to mobile. On supported devices, the picker even integrates with the OS color picker. The layout collapses into a single column under 640px wide, with the large color swatch at the top so you can see your current selection clearly.

No. The Color Converter is free and requires no account. All HEX, RGB, HSL, and CMYK conversions, the nearest-CSS-named-color lookup, the contrast ratio computation, and the WCAG grade all run in your browser. No color data is ever sent to a server or stored between sessions.

RGB defines a color by its red, green, and blue components — how the screen physically produces it. HSL defines a color by hue (the color on the wheel), saturation (intensity), and lightness (how light or dark). HSL is more intuitive for humans because you can adjust brightness without shifting the hue, which is why it is preferred in CSS for creating color variations.

This tool focuses on opaque color conversion between HEX, RGB, and HSL. If you need alpha transparency, append an alpha channel to your CSS value: rgba(59, 130, 246, 0.5) or hsla(217, 91%, 60%, 0.5). The underlying HEX/RGB/HSL values remain the same.
