What does this RGB to HSL converter do?

It converts a RGB color into its HSL equivalent instantly, and also shows the HEX, RGB, HSL and OKLCH values side by side so you can copy whichever you need.

Are alpha / transparency values supported?

Yes. Alpha is optional everywhere — include it (for example an 8-digit hex or an rgba value) and it is carried through to the result; leave it out and the color is treated as fully opaque.

What RGB formats are accepted?

Input is red, green and blue channels from 0–255, optionally with an alpha channel (rgba). Whitespace, commas and the modern "/" alpha syntax are all handled.

Is my color data uploaded to a server?

No. The conversion runs entirely in your browser using local math — nothing is sent anywhere.
