Free RGB to HEX

You have the RGB triplet — from dev tools, a design API, or a color-mixing experiment — and your CSS wants HEX. This converter accepts red, green, and blue values either typed or via sliders, and returns the exact HEX code instantly with a live preview swatch. It is equally handy for precise conversions and for playful color mixing.

How to Use the RGB to HEX

  1. Drag the R, G, B sliders or type exact values (0–255).
  2. The HEX code updates live with the preview swatch.
  3. Copy the uppercase, lowercase, or CSS-variable form with one click.
  4. Everything is computed instantly in your browser.

Features

Three sliders plus numeric inputs accept any red, green, and blue combination from 0 to 255, converting to HEX on every change. The preview swatch renders the mixed color live, making it a genuine color-mixing playground as well as a converter. Copy options include uppercase, lowercase, and CSS-variable-ready formats for different coding styles.

Benefits & Use Cases

Developers convert rgb() values from browser dev tools into HEX for stylesheets. Designers experiment with channel mixing to discover new shades. Data teams translate chart-library RGB outputs into HEX tokens. Students learn how the three channels combine by dragging sliders and watching the result.

Tips

Equal values on all three channels always produce a neutral gray — rgb(128,128,128) is #808080. For quick darkening, halve all three channels; for lightening, move them toward 255 together. If you need the reverse trip, the HEX to RGB tool is one click away.
