What range do the RGB values use?

Each channel (red, green, blue) runs from 0 to 255. Values outside that range are clamped automatically.

How is RGB converted to hex?

Each channel is converted from decimal to a two-digit base-16 number and the three pairs are joined. For example rgb(59, 130, 246) becomes

Does this send my colours to a server?

No. The whole conversion runs locally in your browser — nothing is uploaded.

Why does each channel become two hex digits?

One hexadecimal digit holds 0–15, so two digits hold 0–255 — exactly the range of an RGB channel. That is why a full colour is six hex digits (two per channel), giving #rrggbb.

Are hex codes case-sensitive?

No. #3B82F6 and #3b82f6 are the same colour. CSS and design tools accept either; this tool outputs lowercase by convention.

What is the difference between hex and RGB?

They describe the same colour. RGB lists the red, green, and blue channels as decimal numbers; hex packs the same three values into a base-16 string. Hex is more compact for CSS, RGB is easier to read and tweak.

Can I get a 3-digit shorthand hex?

Only when each channel pair repeats, like #ffcc00, which shortens to #fc0. Most colours need the full 6-digit form, which this converter always produces.

RGB to Hex Converter

Enter red, green and blue values from 0–255 and get the matching hex colour code straight away, with a live swatch you can copy into CSS, SVG, or any design tool.

How it works

A hex colour code packs the three RGB channels into a base-16 string. The converter takes each channel value (0–255), converts it to a two-digit hexadecimal number, and joins the three pairs in red-green-blue order, prefixed with #. Values outside 0–255 are clamped. Because one hex digit covers 0–15, two digits cover the full 0–255 range of a channel, so the result is always #rrggbb.

Example

Convert rgb(59, 130, 246):

59 → 3b
130 → 82
246 → f6
Result: #3b82f6

RGB	Hex
rgb(0, 0, 0)	#000000
rgb(255, 255, 255)	#ffffff
rgb(255, 0, 0)	#ff0000
rgb(59, 130, 246)	#3b82f6

It all runs in your browser — nothing is uploaded.
