RGB to Hex Converter

Turn an rgb() or rgba() color value into its hex equivalent and see hsl() alongside a color swatch.

How it works

  1. 1

    Type or paste an rgb() or rgba() color value — both comma-separated and space-separated syntax are accepted.

  2. 2

    A color swatch appears instantly alongside the matching hex code and HSL value.

  3. 3

    Click any copy button to grab the notation you need. Processing stays in your browser.

Questions

What rgb() formats are accepted?

Integer channels like rgb(255, 128, 0), percentage channels like rgb(100%, 50%, 0%), and modern space-separated syntax like rgb(255 128 0) all work. Add a fourth value for alpha: rgba(255, 0, 0, 0.5).

Why does the tool also show HSL?

Showing all three notations at once saves you an extra conversion step — you get everything in one place.

Does this tool send data anywhere?

No. Conversion is done entirely in your browser; nothing you enter is transmitted.
