Frequently Asked Questions (FAQ)

Can I use the generated QR Codes commercially?

Yes. QR Codes generated here can be used for personal or commercial purposes.

What’s the difference between SVG and PNG?

SVG is vector-based and scales without losing quality—great for printing. PNG is raster, widely supported and easy to handle.

Should I pick vCard or meCard?

vCard is more complete and widely supported; meCard is simpler and quick to scan. Choose the one that best fits your scenario.
