How do I convert a 3-digit hex color?

A 3-digit hex like #F80 is expanded by doubling each digit (#FF8800), then each pair is converted from hex to decimal: R=255, G=136, B=0.

What about hex colors with transparency?

An 8-digit hex (#RRGGBBAA) includes an alpha channel. The tool converts the fourth pair to an opacity value between 0 and 1.

Can I convert RGB back to HEX?

Use the Color Format Converter tool for bidirectional conversion between HEX, RGB, HSL, and other color formats.

Best Free Online HEX to RGB Converter

HEX and RGB are the two most commonly used color formats in web development and design. HEX (#RRGGBB) is compact and widely recognised, while RGB(r, g, b) is often needed when applying opacity with rgba(), computing color arithmetic, or passing values to graphics libraries and APIs that expect numeric channel values. devtoolkit.sh's HEX to RGB Converter handles 3-digit hex codes (automatically expanded), 6-digit hex codes, and 8-digit hex codes with an alpha channel, producing the corresponding RGB or RGBA values. A live color preview confirms the conversion visually. The tool also shows the HSL equivalent, making it a useful single-stop color format reference. Output values are formatted as CSS-ready strings (rgb(255, 128, 0)) and as raw channel numbers for use in JavaScript, Python, design APIs, and other contexts. When working between Figma, browser DevTools, and CSS code, this tool removes the mental overhead of manual hex-to-decimal arithmetic and eliminates transcription errors in color values.
