About Color Converter
Design files hand you HEX, your CSS wants rgba with alpha, and while tuning you prefer HSL hue and saturation — converting colors between formats is constant work. This tool converts colors precisely between HEX, RGB(A), HSL(A), HSV and more locally in your browser, with a live swatch preview so you can verify the result. It never goes online, so your palette and brand colors never leave your device. Paste #FF5733 and you instantly get rgb(255, 87, 51) and hsl(10, 100%, 60%), so you can compare the same color across notations. Practical details: three-digit shorthand like #f00 expands to #ff0000 and four-digit shorthand with alpha (#f008) parses too; because HEX has only 256 levels per channel, a HEX-to-HSL round trip may show a one-unit rounding difference that is normal and invisible; in RGBA/HSLA alpha is a 0-to-1 decimal while 8-digit HEX encodes opacity in the last two hex digits, and the tool maps between them automatically. It is also handy for checking text/background contrast for accessible design.

Use Cases
- Match the design — Convert a designer HEX into the rgb or hsl value your CSS needs.
- Add transparency — Turn an opaque color into rgba for a translucent overlay or shadow.
- Tweak hue — Use HSL mode to adjust hue and lightness for tints and shades in one family.
- Unify variables — Normalize scattered colors to one format for entering design-system tokens.
- Verify preview — Paste an unknown color value and see the swatch to confirm it is right.
FAQ
Does it support shorthand HEX?
Yes. Three-digit shorthand like #f00 is expanded to #ff0000, and four-digit shorthand with alpha (#f008) is parsed too.
Is precision lost going HEX to HSL?
HEX has only 256 levels per channel, so a round-trip may show a one-unit rounding difference — normal and usually invisible to the eye.
How is transparency expressed?
In RGBA/HSLA, alpha is a 0-to-1 decimal; in 8-digit HEX, the last two hex digits encode opacity, and the tool maps between them automatically.
Are CSS color names supported?
Common named colors (red, rebeccapurple) are usually recognized as input, while output is numeric for precise use.
Will the conversion show a color difference?
The notations describe the same color, so conversion itself has no difference. Perceived differences come from monitor gamut and color profiles, so re-check on the target device.
I just need numeric base conversion.
This tool focuses on color formats. For converting a hex number to decimal and similar, use our base converter.
Why can't I paste oklch() or color(display-p3 ...)?
Because this tool targets standard sRGB color spaces (HEX / RGB / HSL / HSV), while oklch() and the color() function are newer syntax defined in CSS Color 4 that many design files and older browsers still don't support. If your design file supplies Oklab / Oklch or wide-gamut display-p3 values, verify the color in an environment that supports them and then convert to sRGB HEX with a regular tool, or use the sRGB approximation your design file also provides. To simply see what the color looks like, treat the preview swatch as a reference first, then convert to the target format manually.
