🎨 RGB to HEX Converter
Enter red, green, and blue values to get a clean 6-digit hex color code — with automatic clamping and rounding so you always get a valid result.
🧮 Convert RGB to Hex
What is an RGB to HEX Converter?
It turns three separate red, green, and blue numbers (0–255 each) into the compact 6-digit hex code that CSS, design tools, and style guides commonly use — the reverse of a hex-to-RGB conversion.
Use it when you've computed or sampled RGB values programmatically and need a shareable hex code for a style guide, when converting a color picked from an image editor, or as the final step after tinting, shading, or blending individual channels.
❓ Frequently Asked Questions
How does the RGB to hex converter work?
Enter a red, green, and blue value from 0–255. Each channel is rounded to the nearest whole number, clamped into the 0–255 range, and converted to a two-digit hexadecimal pair. The three pairs are joined with a leading # to form a standard 6-digit hex color.
What happens if I enter a value above 255 or below 0?
The converter clamps it automatically — anything above 255 becomes 255 (full intensity) and anything below 0 becomes 0 (no intensity) — so you always get a valid hex code rather than an error.
Why is the output always lowercase?
Lowercase hex (#ff8800 rather than #FF8800) is the more common convention in CSS and design tools, and it's what most linters and style guides prefer. Uppercase and lowercase hex are functionally identical to browsers.
Can I convert decimal (non-integer) RGB values?
Yes — non-integer channel values (for example from a blended or interpolated color) are rounded to the nearest whole number before the hex conversion, matching how browsers round fractional rgb() values.
