What input does the Color Converter accept?

It takes a HEX color code. You can paste it with or without the leading #, and both 3-digit shorthand (like #2bf) and full 6-digit codes (like #2b59ff) work. The result shows the matching HEX, RGB, and HSL values.

Does it convert RGB or HSL back to HEX?

Not right now. The current tool reads a HEX code and outputs the equivalent RGB and HSL values. If you only have RGB or HSL, you would need the HEX first to use this converter.

Are the RGB and HSL values accurate for CSS?

Yes. The output is formatted ready to drop into CSS, for example rgb(43, 89, 255) and hsl(227, 100%, 58%). Values are rounded to whole numbers, which matches how browsers display them.

Is anything sent to a server?

No. The conversion runs entirely in your browser using local math, so your color codes never leave your device. That also means it works offline once the page has loaded.

What the Color Converter does

Give it a HEX color code and it hands back the same color written three ways: HEX, RGB, and HSL. That covers the formats designers and front-end developers reach for most. Grabbed a swatch as #2b59ff but your CSS variable expects an rgb() value? Paste it here and copy the line you need. It is handy for matching brand colors, filling in a design token, or just checking what a hue looks like in HSL before you tweak its lightness.

How to use it

Type or paste a HEX color into the input box. The # is optional, and both shorthand like #2bf and full codes like #2b59ff are accepted.
Press the Convert button.
Read the output box, which lists the HEX, RGB, and HSL versions on separate lines.
Copy whichever line you need straight into your stylesheet or design file.

If you enter something that is not a valid HEX code, the tool tells you and shows the expected format, so you are never left guessing.

Why convert colors here

It is quick. There is no upload step and no waiting, because the math happens the instant you click Convert. It is private too: the calculation runs locally in your browser, so your color codes stay on your device and the page keeps working even without a connection. And it is free with no account to create.

The RGB and HSL output is already formatted the way CSS wants it, parentheses and percentage signs included, so you can paste without cleanup. Values are rounded to whole numbers to mirror how browsers render them.

A quick tip

Working in HSL makes shade variations easy: convert your base HEX, then nudge the last number (lightness) up or down to build a lighter or darker version of the same hue without losing the color’s character.
