RGB to HEX
Convert RGB color values to HEX color codes
RGB to HEX converts red, green and blue values (0-255 each) into their 6-digit HEX equivalent, validating that each channel is actually a valid number in range before converting.
How to use RGB to HEX
- 1
Enter the red, green, and blue values (0-255 each).
- 2
Click "Convert" to get the HEX value.
- 3
Copy the resulting HEX color code.
Everything you need to know about RGB and HEX color codes
What's the difference between RGB and HEX?
Both describe the exact same color in different notations. RGB (like `rgb(124, 58, 237)`) writes out red, green, and blue as three separate 0–255 numbers; HEX (like `#7c3aed`) packs the same three values into a compact six-digit code. Which one you need depends on what you're writing code for.
When you actually need this
- Converting a color from a design spec or codebase that uses RGB into the HEX format CSS most commonly uses.
- Standardizing color values across a project that mixes both notations.

Frequently Asked Questions
What happens if I enter a value above 255 or below 0?
It's rejected with a clear error naming which channel is out of range, since RGB channels are only valid between 0 and 255.
Does this round decimal RGB values?
Yes — each channel is rounded to the nearest whole number before being converted to its two-digit HEX representation.
Is HEX just another way of writing the same color as RGB?
Yes — HEX and RGB represent exactly the same color space, just in different notations; converting between them loses no information.
Does this tool send my values to a server?
Yes — they're sent to our servers to compute the result and the result is returned to you; nothing is stored.
Is this tool free to use?
Yes — completely free, with no signup and no usage limits for casual use.
