RGB to HEX Converter
Enter RGB values and get the hex color code — accepts both rgb(r, g, b) syntax and plain comma-separated numbers.
Frequently asked questions
What if my RGB values are percentages?
CSS also allows percentage syntax like rgb(31%, 27%, 90%). Multiply each percentage by 255 and round — 31% becomes 79. Or just use the numbers directly; this tool expects the 0-255 integer form.
Can RGB have a fourth value?
Yes — the alpha channel, rgb(79, 70, 229, 0.5) is 50% transparent. In hex it becomes an 8-digit code: #4F46E580. This converter handles the three color channels; use our Color Converter for full alpha support.
Why is hex preferred in CSS?
Hex is shorter, has been valid since CSS 1, and copies cleanly between design tools like Figma and your editor. Both notations are exactly equivalent to the browser — pick whichever your team reads best.
