RGB to HEX Converter
Pulling colors from Photoshop to use on your website? Our free RGB to HEX Converter perfectly translates 0-255 Red, Green, and Blue values into the standard HTML/CSS hexadecimal format.
What is the RGB to HEX Converter?
The RGB to HEX Converter is a developer utility that takes three decimal integers representing Red, Green, and Blue (ranging from 0 to 255) and converts them into a single 6-character Base-16 hexadecimal string.
How to use the RGB to HEX Converter
- Enter the Red value (0-255).
- Enter the Green value (0-255).
- Enter the Blue value (0-255).
- The tool calculates the equivalent HEX code and provides a color preview.
Example
You enter R: 255, G: 255, B: 255. The tool converts 255 to hex, which is FF. It strings them together: FF + FF + FF. The output is #FFFFFF, which represents pure white.
Understanding Your Results
The resulting 6-character string is the exact web-ready code you need to paste into your CSS file or HTML attributes to render the color.
Common Use Cases
- Web Design: Taking colors identified in a branding document (often listed in RGB) and preparing them for frontend coding.
- Image Editing: Using the eye-dropper tool in an image editor to find the RGB, then converting it to build a web button of the exact same color.
- Data Visualization: Programmatically generating HTML colors based on numerical data arrays.
How it Works
The tool takes each base-10 integer and performs a mathematical base conversion to base-16. If the resulting hex value is a single digit (like 'A'), it pads it with a leading zero ('0A'). It then concatenates the three pairs together and adds a '#' prefix.
Tips & Accuracy Notes
- •RGB values must be between 0 and 255. Entering higher numbers will usually cap at 255 (FF) or result in an invalid color.
- •The '#' symbol is technically required in CSS, but many graphic design tools accept the 6 characters without the hashtag.
