RGB to HEX Converter: Switch Between Color Formats

9 min read

RGB and HEX both describe colours: RGB with three numbers (0–255), HEX with a single string like #FF0000. Design tools and code use one or the other, so a RGB–HEX converter saves time when you need to move between formats.

RGB

  • Three values: red, green, blue (e.g. 255, 0, 0 for red).
  • Used in CSS as rgb(255, 0, 0), in some APIs and design tools.

HEX

  • Six hex digits (or three for shorthand), e.g. #ff0000 or #f00.
  • Common in design tools, CSS, and HTML. Easy to copy and share.

When to convert

  • Design handed off in HEX; your code expects RGB (or the other way around).
  • Matching a colour from a different source (e.g. brand guidelines in HEX, CSS in RGB).
  • Debugging or tweaking colours in dev tools.

Our RGB to HEX Converter works both ways. Enter RGB values or a HEX code and get the equivalent. Conversion runs in your browser; nothing is sent to our servers.
