HEX to RGB Converter

Convert a hexadecimal color code into RGB and RGBA values. Paste any valid HEX, whether it is a short 3-digit form like #f0c, a full 6-digit code, or an 8-digit code with alpha, and get the equivalent rgb() and rgba() strings immediately. The converter validates your input and explains what is wrong instead of silently guessing, so a mistyped code gives a clear message rather than a misleading result. You also see the HSL equivalent and the closest CSS color name for context. Copy any value with a single click. All conversion happens in your browser using shared, tested color math, so results are consistent across every tool on the site.

How to use the HEX to RGB Converter

  1. Enter a HEX code. Type or paste a 3, 4, 6, or 8-digit HEX value, with or without the leading #.
  2. Read the RGB output. See the rgb() and, when alpha is present, rgba() values update instantly.
  3. Copy the result. Click copy to place the RGB or RGBA string on your clipboard.

Examples

  • Six-digit code: #3498db converts to rgb(52, 152, 219).
  • Code with alpha: #3498db80 converts to rgba(52, 152, 219, 0.5).

How it works

A HEX code encodes the same red, green, and blue channels as RGB, just in base-16. Each pair of hex digits (00–ff) maps to a 0–255 value. A fourth pair encodes alpha as 0–255, which converts to a 0–1 opacity. Because both notations describe identical channels, HEX to RGB is exact with no rounding loss.

Common use cases

  • Getting rgb() values for a canvas, SVG, or WebGL fill
  • Adding an alpha channel to an existing HEX color
  • Double-checking a HEX code before using it in code

Frequently asked questions

What HEX formats are accepted?

3-digit (#f0c), 4-digit with alpha (#f0c8), 6-digit (#ff00cc), and 8-digit with alpha (#ff00cc80), with or without the leading #.

How is alpha handled?

An 8-digit or 4-digit HEX includes alpha, which is converted to a 0–1 value in the rgba() output.

What happens with an invalid code?

You get a clear validation message explaining the problem, such as an invalid length or character, rather than a guessed color.

Is the conversion exact?

Yes. HEX and RGB describe the same channels, so the conversion is exact with no rounding difference.
