What is the difference between HEX and RGB?

HEX is a 6-digit hexadecimal representation while RGB uses three decimal numbers (0-255) for red, green, and blue. Both describe the same color in different notation.

Does this tool support 3-digit HEX shorthand?

Yes. Codes like #F00 are expanded to #FF0000 before conversion.

Can I include alpha transparency?

Use the HEX to RGBA tool if you need an alpha channel. This tool returns plain RGB only.

Why does the preview look slightly off on my screen?

Color rendering depends on your monitor calibration and color profile. The numeric values are exact regardless of display.
