What is RGB to HEX Conversion?
RGB values from design tools, color pickers, and image editors need to become hex codes for your CSS. Our RGB to HEX converter makes this translation instant and error-free.
Every color you see on screen is a combination of red, green, and blue light—each channel ranging from 0 (none) to 255 (maximum intensity). When designers hand off rgb(99, 102, 241), developers need #6366F1 for their stylesheets.
Why Convert RGB to HEX?
Hexadecimal is the web's native color language. It's more compact than RGB (6 characters vs. 13+), widely supported, and instantly recognizable to developers. Most CSS codebases standardize on hex for consistency.
Hex codes also work everywhere: CSS custom properties, Tailwind configs, Sass variables, design tokens, and brand guidelines all use hex as the common format.
How the Conversion Works
The conversion reverses the hex-to-rgb process:
1. Take each RGB value (0-255) 2. Convert to base-16 (hexadecimal) 3. Pad single digits with leading zero 4. Combine with # prefix
For example: rgb(99, 102, 241) becomes 99→63, 102→66, 241→F1, giving us #6366F1.
Common Use Cases
- Creating CSS stylesheets from design specs
- Building Tailwind custom color configs
- Standardizing brand color documentation
- Shortening color values in code
Pro Tip
When your RGB values have matching pairs (like 17, 34, 51), the hex can be shortened to 3 digits: #123.
