Do these generated QR codes expire?

No. All QR codes generated on ZeroTool are standard static QR codes that encode your data directly into the pixel pattern. They never expire, contain no tracking redirects, and remain functional forever.

Can I add my business logo to the center of the QR code?

Yes. You can upload any PNG, JPEG, or SVG logo. The generator automatically switches to High (H) error correction (30% redundancy) so the QR code scans reliably even with a center icon overlay.

Is my data or WiFi password uploaded to your servers?

Zero server transmission. The QR code pixel matrix is generated strictly in your computer's browser memory (RAM) via client-side JavaScript. Zero bytes are uploaded to any cloud backend.

What formats can I download the QR code in?

You can export high-resolution raster PNG images (512px, 1024px HD, or 2048px 4K print-ready) or vector SVG files that scale infinitely for billboards and business cards without pixelation.
