Frequently Asked Questions

Is this QR code generator completely free and private?

Yes. ImgZero generates and renders all QR codes entirely inside your browser using client-side JavaScript and Canvas APIs. Your URLs, contact details, payment information, and uploaded logos are never sent to any server.

Do generated QR codes ever expire?

No. All QR codes generated on ImgZero are static QR codes containing the direct encoded information. They never expire, require no subscription, and have zero intermediate redirect hops or click tracking.

What is Local Scan Verification?

ImgZero tests the actual rendered QR image in real-time using an embedded local decoder (jsQR). This verifies that your chosen colors, logo size, and corner styles remain easily decodable before you download or print.

Can I use the generated QR codes for commercial printing?

Yes. You can export scalable SVG vector files that scale to any billboard or poster size without pixelation, or print-ready PDF documents with standard margins and captions.

How does UPI QR code generation work?

The UPI mode creates a standard static payment intent URI (upi://pay?...) compatible with all major Indian payment apps like Google Pay, PhonePe, Paytm, and BHIM. ImgZero does not process, intermediate, or store any payment data.
