HEX to RGB Converter

What is it?

A color converter is a small utility that translates a color code from one notation to another, so you can use the same color in HTML, CSS, design tools and printing. Our HEX to RGB converter takes any 3, 6 or 8 digit HEX value (with or without the leading hash) and instantly displays the equivalent RGB, RGBA and HSL representations. You also get a large preview swatch, the contrasting black-or-white text suggestion, and the closest CSS named color. The whole experience runs in your browser, so designers and developers can work fast without ever leaving the page.

How to use it

1. Type or paste a HEX color into the input — for example #3366ff or 36f.
2. The RGB, RGBA and HSL values appear immediately, together with a preview.
3. Use the color picker to pick a color visually instead of typing.
4. Click any value to copy it — handy for CSS, Figma, Sketch or print specs.
5. Toggle the alpha slider to add transparency and get RGBA or 8-digit HEX.

Why use this tool

Designers, front-end developers and marketers all juggle colors in multiple formats. Brand guidelines often use HEX, while accessibility tools want RGB to compute contrast, and CSS animations look cleaner in HSL. Manual conversion is tedious and error-prone, especially when an opacity channel is involved. Our tool does the math instantly and keeps every notation in sync. The live swatch helps you see the actual color before committing it to a design, while the contrasting-text recommendation is great for buttons and badges. Because everything is computed locally, you can paste internal brand HEX values without sending them anywhere — useful in agencies and corporate environments where unreleased palettes need to stay confidential.
