Do QR codes generated with this tool ever expire?

No. These are static QR codes that encode your data directly into the pixel pattern. They never expire and do not depend on external redirect servers.

Are my Wi-Fi credentials or contact details uploaded to your server?

Never. The QR code generation runs 100% client-side inside your browser's JavaScript engine. Your passwords and data never leave your device.

Which file format should I download for printing?

For print media (flyers, business cards, posters), download the SVG format as it is infinitely scalable without pixelation. For digital screens, use the high-resolution PNG.

What is QR Code Error Correction?

Error correction allows a QR code to be scanned even if part of it is dirty or covered. Higher error correction (e.g. High 30%) produces denser patterns but is more resilient to damage.
