About this tool
When a design tool hands you RGB numbers, CSS usually wants a hex code. Enter the three channels and this converter produces the exact 6-digit hex, validated so out-of-range values are caught before they become broken colors.
The preview swatch updates with every keystroke, giving you immediate visual confirmation.
How to use
- Enter the red, green, and blue values (0–255 each).
- The hex code appears with a live preview.
- Click Copy to grab the hex value.
Frequently asked questions
The converter flags it as invalid until all three channels are within 0–255, since hex colors cannot represent values outside that range.
Lowercase, e.g. #ff5733. Both cases are valid CSS and render identically.
Just pull out the three numbers and type them into the fields — rgb(255, 87, 51) becomes 255, 87, 51.
