Color Converter
Convert any color between HEX, RGB, HSL, and HSV with a live picker and copy buttons.
About the Color Converter
The Color Converter turns any color into every common format at once. Pick a color with the native color picker or paste a HEX code, and the tool instantly shows you the matching HEX, RGB, HSL, and HSV values side by side, along with a large preview swatch. Each value has its own one-click Copy button, so you can grab exactly the format your CSS, design app, or code needs without hunting through a chart.
Different tools speak different color languages. A design mockup might give you HEX, a CSS gradient might want HSL, and an image editor might report HSV. Instead of doing the math in your head or bouncing between websites, this converter keeps all four representations of the same color in sync. Change the HEX input and everything updates; drag the picker and everything updates. The conversions are done with exact color math — the same formulas used by browsers and design software — so what you copy is what you'll see on screen.
How to use
- Pick a color using the color picker, or type a HEX code into the "HEX value" box (both
#abcshorthand and full#aabbccare accepted). - Read the results — HEX, RGB, HSL, and HSV for that exact color appear together, and the large swatch previews it.
- Copy any format by clicking the Copy button on its row; a checkmark confirms it landed on your clipboard.
- Adjust freely — edit the HEX field or nudge the picker and every value, plus the swatch, recalculates instantly.
If you type something that isn't a valid color, the tool tells you gently and keeps the last good preview visible so you never lose your place.
Frequently asked questions
What color formats does this convert between?
It converts between the four most common web and design formats: HEX (#RRGGBB), RGB (red, green, blue on a 0–255 scale), HSL (hue, saturation, lightness), and HSV (hue, saturation, value, sometimes called HSB). All four are shown simultaneously for whatever color you enter, so you never have to run one conversion at a time.
Can I paste a shorthand hex code like #abc?
Yes. The HEX input accepts both three-digit shorthand (#abc, which expands to #aabbcc) and full six-digit codes (#aabbcc). The leading # is optional, and the input is case-insensitive, so #FFF and fff both work.
What's the difference between HSL and HSV?
Both describe color by hue (the angle on the color wheel) and saturation, but they treat brightness differently. HSL uses lightness, where 100% is always white and 50% is the pure, most vivid color. HSV uses value, where 100% is the brightest version of the color and 0% is black. HSL is common in CSS; HSV is common in image editors and color pickers.
Are the conversions accurate?
Yes. The tool uses the standard mathematical formulas for converting between RGB, HSL, and HSV, the same ones defined for the web platform. HEX and RGB are exact; HSL and HSV values are rounded to whole numbers for readability, which is the precision virtually every design tool and CSS use case needs.
Does the converter send my colors to a server?
No. Everything runs entirely in your browser using small pure functions — nothing you pick or type is uploaded or logged. Once the page has loaded, the tool keeps working even if you go offline, and there are no network requests involved in any conversion.
Why does the preview stay the same when I type an invalid code?
While you're mid-edit, a partial code like #3b isn't yet a valid color. Rather than flashing black or an error swatch, the tool keeps showing your last valid color and displays a short hint. As soon as the input becomes a complete, valid HEX code again, the swatch and all four values update.
All conversions happen client-side in your browser — there is no upload, no account, and no waiting on a server. That makes the Color Converter fast, private, and usable offline once the page has loaded, whether you're matching a brand color, tuning a gradient, or translating a value between your design app and your stylesheet.
