HEX to RGB Converter - Online Color Code Translator

A HEX color code is a 6-character hexadecimal representation of a color used in web design, CSS, and digital graphics. It begins with a hash symbol # followed by three pairs of hexadecimal digits (0-9, A-F), representing the intensity of Red, Green, and Blue channels respectively. For example, #FF5733 means Red=FF (255), Green=57 (87), Blue=33 (51). Shorthand 3-digit HEX codes like #F53 are also valid and expand to #FF5533.

RGB stands for Red, Green, Blue — the three primary colors of light. In digital displays, every color is created by mixing these three channels, each ranging from 0 to 255. The RGB format is expressed as rgb(255, 87, 51). While HEX and RGB represent the exact same color information, HEX uses base-16 notation (compact for code) and RGB uses decimal notation (more human-readable). Designers often prefer HEX for CSS, while RGB is common in graphic software and JavaScript.

To convert HEX to RGB manually:
1. Take the 6-digit HEX code (remove the #).
2. Split into three pairs: RR, GG, BB.
3. Convert each pair from hexadecimal (base-16) to decimal (base-10).
For example, #3B82F6:
• 3B = 3×16 + 11 = 59 (Red)
• 82 = 8×16 + 2 = 130 (Green)
• F6 = 15×16 + 6 = 246 (Blue)
Result: rgb(59, 130, 246). Use our free converter above for instant results!

Yes! Our converter fully supports shorthand 3-digit HEX codes. A 3-digit HEX like #ABC is automatically expanded to #AABBCC before conversion. This means #F80 becomes #FF8800, which converts to rgb(255, 136, 0). Simply type the 3-digit code and the tool handles the rest instantly.

Each RGB channel accepts integer values from 0 to 255. A value of 0 means no intensity (pure black if all channels are 0), while 255 means full intensity (pure white if all channels are 255). This gives 256 × 256 × 256 = 16,777,216 possible colors — the standard True Color palette used across all modern displays and browsers.

Absolutely. This HEX to RGB converter is designed specifically for web developers and designers. Both HEX and RGB formats are widely used in CSS, and our tool produces clean, copy-ready output. Use HEX for shorthand properties like color: #3B82F6; or RGB when you need to add alpha transparency with rgba(59, 130, 246, 0.5). The tool also displays HSL values for modern CSS workflows.

A HEX color code must consist of exactly 3 or 6 characters using only digits 0-9 and letters A-F (case-insensitive). Common mistakes include: using letters beyond F (like G or Z), including the # symbol in the character count, or typing an incomplete code. Our tool strips the # automatically and validates the remaining characters. If invalid, an error message guides you to correct the format.

No functional difference. HEX color codes are case-insensitive — #3b82f6 and #3B82F6 represent the exact same color. Most modern CSS minifiers use lowercase, while design tools like Figma and Adobe often display uppercase. Our converter accepts both and outputs uppercase by default for readability, but you can use either in your code.

HSL stands for Hue, Saturation, Lightness — an alternative color model that's often more intuitive for designers. Hue (0°–360°) represents the color wheel position, Saturation (0%–100%) is the color intensity, and Lightness (0%–100%) is the brightness. Our tool computes HSL from your RGB/HEX input automatically, making it easy to understand and adjust colors perceptually. Modern CSS supports hsl() and hsla() functions natively.
