Hex to RGB Color Converter

What is a hex to RGB converter?

A hex to RGB converter translates colour codes between hex format (#FF8800) and the red, green, blue values (rgb(255, 136, 0)) used in CSS and design tools. Both represent the same colour — one in base 16, one in decimal.

How this converter works

• In hex mode, paste a colour like #FF8800 and it decodes the three pairs into RGB values.
• In RGB mode, enter r, g, and b values and it builds the hex code.
• A live swatch shows the colour as you convert.
• Short 3-digit hex (#F80) is expanded automatically.

How to use the result

1. Use the hex form for HTML and CSS; use RGB for image editors and canvas APIs.
2. Match a brand colour by pasting its hex and reading the RGB equivalent.
3. Adjust brightness by tweaking the RGB channels and watching the swatch.
4. If values land outside 0–255, the converter clamps them — fix the source if the colour looks off.

How do you convert hex to RGB?

Split the six hex digits into three pairs — one per channel — and convert each pair from base 16 to decimal. #FF8800 becomes FF (255), 88 (136), and 00 (0), so rgb(255, 136, 0). It’s the same number base conversion the base converter performs, applied to colours.

Common mistakes

• Forgetting the # sign or including it inconsistently. The converter accepts either, but copy the code cleanly.
• Reading hex digits as decimal. A = 10 through F = 15 in each digit position.
• Assuming 8-digit hex (with alpha) is handled. This tool covers standard 6-digit colours — the leading alpha pair is ignored.

Colour codes are just numbers — the number base converter explains the hex math behind them, and the scientific notation converter handles the different notation scales you meet in design specs.
