How do 3-digit HEX codes (#RGB) convert to RGB?

Each single hexadecimal digit is duplicated: for example, #F0A expands to #FF00AA, which converts to rgb(255, 0, 170).

How does 8-digit HEX with alpha (#RRGGBBAA) work?

The first six characters represent Red, Green, and Blue (00 to FF). The last two characters represent the alpha opacity channel from 00 (0% opacity, completely transparent) to FF (100% opacity, fully opaque).

Can I pick colors visually with a color picker?

Yes! Click the "Pick Color" button next to the input to open your operating system's native color picker. The HEX and RGB values update in real time.

Is this converter free and private?

Yes. It runs entirely inside your browser JavaScript engine with zero server communications or tracking.
