Convert colors between HEX, RGB, HSL formats

Color Converter — Convert Between HEX, RGB, HSL, HSV, CMYK Color Formats

  1. Enter a color value in any format: HEX (#3B82F6 or #3BF), RGB (rgb(59, 130, 246)), HSL (hsl(217, 91%, 60%)), HSV, or CMYK. The converter accepts all standard color notations including shorthand hex and rgba/hsla with alpha channels.
  2. The tool instantly converts your input to all other color formats and displays them simultaneously. Each format is shown with its exact value and a live color preview swatch. Adjust any value and all formats update in real time.
  3. Copy the color code in your desired format for use in CSS, design tools, print specifications, or code. The converter handles alpha/opacity values and displays a checkerboard transparency preview when applicable.

Frequently Asked Questions

Is the Color Converter free?

Yes, completely free with no limits. Convert unlimited colors between all supported formats.

Are my color values uploaded anywhere?

No. All conversion is calculated locally in your browser. Your design work stays private.

When should I use each color format and how do they relate to each other?

HEX is the web standard — compact, universally supported, and easy to copy-paste. Use it for CSS, HTML, and most web frameworks. RGB is the native representation of digital screens (each pixel has red, green, and blue subpixels); use it when you need alpha transparency via rgba(). HSL describes color in human terms: Hue (0°=red, 120°=green, 240°=blue on a circular wheel), Saturation (color intensity), and Lightness (brightness). HSL is preferred by designers for creating color schemes — lighten/darken a color by adjusting L, or find complementary colors by adding 180° to the hue. HSV/HSB is similar to HSL but uses "Value/Brightness" instead of "Lightness" and is used in Photoshop and GIMP. CMYK (Cyan, Magenta, Yellow, Key/Black) is for print — CMYK colors are subtractive (ink absorbs light) while RGB/HEX colors are additive (light emitted from screen). Note that RGB-to-CMYK conversion is approximate because some RGB colors (especially bright neon greens and deep blues) cannot be reproduced in CMYK printing.
