Frequently Asked Questions

Does it work with alpha (transparency)?

Yes — paste #RRGGBBAA or rgba(...) and the alpha channel is preserved across all output formats.

Why does my CMYK look different from print?

CMYK conversion uses a sRGB → CMYK approximation. For exact print color, use your printer's color profile.

Is the calculation done locally?

Yes — pure browser JavaScript. No network requests.
