What input formats are accepted?

Both plain comma-separated numbers ("59, 130, 246") and a full rgb(...) string are accepted.

What happens if a value is above 255?

You'll see a clear error message, since RGB channel values must be between 0 and 255.

Is my color data sent anywhere?

No — conversion happens entirely in your browser.

Does this support rgba() with transparency?

The tool reads the first three numeric values it finds, so an alpha channel value would be ignored rather than converted.

Can I convert the other direction, HEX to RGB?

Yes — use the dedicated HEX to RGB tool for that direction.

Is the resulting HEX code always 6 digits?

Yes — the output is always a standard 6-digit HEX code.

What Is RGB to HEX Conversion?

RGB values describe a color as three numbers from 0 to 255 representing red, green and blue intensity, while HEX packs the same three values into a compact six-digit code prefixed with #. Converting from RGB to HEX is a common step when a design tool gives you one format but your CSS needs the other.

This tool accepts RGB values in several common formats — comma-separated numbers, or a full rgb(...) string — and instantly returns the matching HEX code with a live color swatch.
