Color Converter

Every design tool speaks a different color language — some want a HEX code, others RGB values, and CSS prefers HSL. This free color converter lets you type a color in any of the three formats and instantly sees the other two, plus a live preview swatch you can copy straight into your project.

What is a Color Converter?

A color converter is a tool that translates a color between the three most common formats developers use every day: HEX, RGB and HSL. Instead of doing arithmetic by hand or hunting for a matching code, you type one representation and the converter works out the rest instantly.

HEX is the #RRGGBB code used in HTML and CSS; RGB expresses a color as three red, green and blue values from 0 to 255; and HSL describes a color by its hue (the angle on the color wheel), saturation and lightness. Many color pickers, design suites and branding docs each prefer a different one, so switching between them is a constant task in frontend work.

Designers and developers rely on color conversion to match a brand hex in Figma to an RGB value in code, to tweak a gradient by adjusting HSL lightness, or to communicate a shade to a client who only knows a HEX code. The swatch gives you a true preview, and because the work happens in your browser it is private and needs no internet connection.

How to use the Color Converter

Type or paste a color in one of the three formats: a HEX code like #3498db, an RGB value like rgb(52, 152, 219) or an HSL value like hsl(204, 70%, 53%).
The converter detects the format and fills in the other two fields automatically.
Check the live swatch to confirm the color is the one you wanted.
Use the Copy button next to the format you need, or click the swatch, to place it on your clipboard.

Example

Input: #3498db

The converter returns RGB (52, 152, 219) and HSL (204°, 70%, 53%), with the swatch showing the classic flat-UI blue. Paste rgb(52, 152, 219) and you get the same #3498db and HSL values back.

Who is this color converter for?

This free color converter is built for anyone who needs to make a conversion quickly, but a few groups reach for it most often.

Students and young adults: In art, design and coding classes, a quick color converter turns a chosen shade into the HEX or RGB value a project needs. It is a color converter for students learning how colors are represented on screen.
Designers and developers: Converting a brand hex in Figma to an RGB value in code is a daily task. This free color converter is a color converter for designers and developers who need to match a shade fast.
Professionals: Marketing and product teams who share brand palettes across documents keep a color converter handy to verify an exact tint before it ships.
Curious users: Anyone who has wondered how #FF0000 becomes red can use the color converter to explore the math behind every color, privately in the browser.

Color conversion reference table

Each row is computed with the same HEX-to-RGB-to-HSL math the converter runs in your browser.

Color	HEX	RGB	HSL
Red	#FF0000	rgb(255, 0, 0)	hsl(0, 100%, 50%)
Green	#00FF00	rgb(0, 255, 0)	hsl(120, 100%, 50%)
Blue	#0000FF	rgb(0, 0, 255)	hsl(240, 100%, 50%)
Yellow	#FFFF00	rgb(255, 255, 0)	hsl(60, 100%, 50%)
White	#FFFFFF	rgb(255, 255, 255)	hsl(0, 0%, 100%)
Sky blue	#3498DB	rgb(52, 152, 219)	hsl(204.1, 69.9%, 53.1%)

Common use cases

Matching a brand HEX color to the RGB value your CSS or design tool expects.
Adjusting a shade by changing only the lightness in HSL to build gradients and tints.
Communicating a color to a client or teammate who works in a different format.
Quickly copying a color from a design mockup into code or into a spreadsheet.

Pro tips

HSL is easiest for tweaks: keep hue and saturation fixed and adjust lightness to darken or lighten a color.
Remember that many colors used in print are CMYK, which this converter does not cover — check with your print provider first.
Use the swatch as your source of truth; two different-looking codes can produce the same color on screen.
The converter clamps out-of-range values, so a green of 300 becomes the nearest valid value rather than erroring.

FAQ

What is a HEX color code?

A HEX code is a six-digit representation of a color, written as a short #RRGGBB value, where each pair of digits is a red, green or blue value from 00 to FF.

What does RGB stand for?

RGB stands for red, green and blue, the three channels that mix to form any screen color, each ranging from 0 to 255.

What is HSL?

HSL stands for hue, saturation and lightness. Hue is an angle from 0 to 360 degrees on the color wheel, saturation is the intensity, and lightness is how light or dark the color is.

How do I convert HEX to RGB?

Type that is not converted directly — it runs in your browser. Split the HEX code into three pairs, convert each pair from base-16 to decimal, and you get the three RGB values.

Which format should I use in CSS?

All three work in modern CSS. HEX is the most common, RGB is handy for opacity, and HSL is often the most readable for hand-tuning colors.

Does the converter handle RGB with alpha or opacity?

This converter handles the three standard channels and clips out-of-range values; if you need alpha, you can append the opacity to the HEX or RGB in the field that uses it.

Is this color converter free and private?

Yes — it is completely free and runs entirely in your browser, so nothing is uploaded or stored.

Why does the same color appear different across formats?

The three formats are just different ways to describe the same color, so the swatch stays identical. Differences appear only if a value is slightly off or clipped.

Can I copy a single format?

Yes. Each format has its own copy button, so you can grab just the HEX, RGB or HSL value you need.

Does it work offline?

Yes. Once the page is loaded, the conversion runs locally with no internet connection required.
