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), and HSL(A) 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. Tip: Bookmark this tool for quick access whenever you need format conversion. All processing happens locally in your browser — no data upload, so feel free to paste sensitive content.

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.
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.
Any browser compatibility requirements?
This tool works in all modern browsers (Chrome, Firefox, Edge, Safari). No plugins or extensions required.
Can I use it offline?
After initial load, most features work offline. The core logic runs entirely in your browser with no network dependency.
