RGB to HEX Converter - Online Color Translator

RGB (Red, Green, Blue) represents colors using three decimal values (0–255) for each channel. For example, rgb(255, 0, 0) is pure red.
HEX (Hexadecimal) is a compact representation using a 6-character code prefixed with #. Each pair of hex digits (00–FF) corresponds to one RGB channel. For example, #FF0000 is the same pure red. HEX is widely used in web design, CSS, and graphic design tools because it's concise and easy to copy.

To convert RGB to HEX manually:
1. Take each RGB value (0–255).
2. Convert each decimal value to a two-digit hexadecimal number (00–FF).
3. Concatenate them with a # prefix.
Example: rgb(255, 102, 0) → R=255=FF, G=102=66, B=0=00 → #FF6600.
You can use the formula: divide by 16 to get the first hex digit, and take the remainder for the second. Or simply use this converter tool for instant results!

3-digit HEX (e.g., #F60) is a shorthand where each digit is duplicated: #F60 = #FF6600. It's supported in CSS and saves space.
8-digit HEX (e.g., #FF6600CC) includes an alpha (transparency) channel. The last two digits represent opacity: 00 = fully transparent, FF = fully opaque. This is part of the CSS Color Level 4 specification and is supported in all modern browsers.

Yes! Modern browsers support 8-digit HEX codes with an alpha channel. The format is #RRGGBBAA, where AA represents the alpha (opacity) value in hexadecimal (00–FF). For example, #FF660080 is the color #FF6600 at 50% opacity. This tool automatically generates 8-digit HEX when the alpha slider is below 100%.

RGB values range from 0 to 255 because each channel is represented by 8 bits (1 byte) of data. With 8 bits, you can represent 2⁸ = 256 distinct values (0–255). This gives a total of 256 × 256 × 256 = 16,777,216 possible colors (often called "16.7 million colors" or "True Color"). This range is the standard for digital displays, web browsers, and most image formats.

HSL stands for Hue, Saturation, and Lightness. It's an alternative way to describe colors that's often more intuitive for designers:
• Hue (0°–360°): the color type (0°=red, 120°=green, 240°=blue).
• Saturation (0%–100%): the intensity/purity of the color.
• Lightness (0%–100%): how light or dark the color is.
HSL is mathematically derived from RGB. This tool shows the HSL equivalent of any RGB/HEX color you create.
