Common Inquiries Before You Write

Do I need permission to use QR Studio codes commercially?

No permission required. All generated codes are 100% royalty-free for both personal and commercial use without attribution.

Can you recover or edit a QR code I generated earlier?

Because QR Studio operates entirely client-side with zero server storage, we do not store your data. We cannot access, edit, or recover previously generated codes.

What format should I use for commercial packaging print?

Always use the SVG vector export. It scales infinitely without raster degradation, ensuring optimal scannability at any print size.
