HEX to RGB Converter

Convert colours between HEX, RGB, RGBA, HSL and CSS formats with a live swatch preview. Copy production-ready values for design and code.

The HEX to RGB Converter translates colour values between HEX, RGB, RGBA, HSL and CSS-ready formats, with a live swatch so you can see the colour as you type. Designers and developers use it constantly when a design tool exports one colour format but the codebase expects another, or when building a colour scale that needs HSL's intuitive lightness control.

Paste in a hex code like #FF5733, or start from RGB or HSL values instead, and every other format updates instantly alongside a preview swatch. Copy any value straight into your CSS, design tool or code editor. Because conversion runs in the browser, there's no delay and no need to open a separate design app just to check what a colour looks like in a different notation.

How to use the HEX to RGB Converter

1. Enter a HEX colour code, or switch input mode to RGB or HSL.
2. Watch the live swatch update to preview the exact colour.
3. Check the converted values shown in HEX, RGB, RGBA and HSL formats.
4. Adjust sliders or type new values to fine-tune the colour.
5. Copy the format you need directly into your CSS or design file.

Why use this tool

All formats at once

See HEX, RGB, RGBA, HSL and CSS-ready output simultaneously instead of converting one format at a time in separate tools.

Live colour preview

A visible swatch updates as you type, so you can confirm the colour looks right before copying it into a project.

Ready for code and design

Copy values in the exact syntax your CSS or design tool expects, saving the manual reformatting that's easy to get wrong by hand.

Common use cases

• Converting a HEX brand colour from a style guide into RGBA for a CSS overlay with transparency.
• Building a design system's colour scale by adjusting HSL lightness values.
• Matching a colour picked from an image editor to the CSS value used in code.
• Checking what a hex code looks like before committing it to a stylesheet.
• Converting between formats when moving assets between design tools with different colour notations.

How HEX to RGB conversion works

A hex colour packs three byte pairs for red, green and blue. #FF5733 splits into FF, 57 and 33, which convert from base 16 to decimal as rgb(255, 87, 51) — the same colour, expressed in a different numbering system.

When to reach for HSL

HSL separates hue, saturation and lightness, which makes building tints and shades intuitive: keep hue and saturation fixed and vary only lightness to generate a consistent colour scale for buttons, borders and backgrounds.

RGBA and transparency

RGBA adds a fourth alpha channel for transparency, useful for overlays and hover states. HEX and plain RGB have no transparency component, so converting to RGBA is often the step needed before adding opacity in CSS.

How does HEX to RGB conversion work?

HSL makes tints and shades intuitive: keep hue and saturation and change only lightness to build a consistent colour scale for a design system.
