Why use this tool and other frequently asked questions?

Are the QR codes I generate uploaded to your servers?
No. All QR code generation happens locally in your browser using the Canvas API. Your URLs, text, WiFi passwords, and business card data never leave your device.
Can I add my logo to the QR code?
Yes! Switch to the Logo tab in the Design section and upload any PNG or SVG image. It will be centered on the QR code with a white padding background to maintain scan reliability.
What content types are supported?
ZerofyTools QR Generator supports: Website URLs, Digital Business Cards (vCard 3.0), plain Text, WiFi credentials (WPA/WPA2, WEP, open), PDF links, and App Store URLs.
Will the QR code scan correctly with a logo?
Yes. We use medium error correction level (15% data recovery), which provides enough redundancy for logos that cover up to ~20% of the QR code area.
What image formats can I download?
You can download your QR code as a high-resolution PNG (recommended for best quality) or JPG. The canvas renders at full resolution for crisp printing.
Can I generate a WiFi QR code?
Yes! Select the WiFi tab, enter your SSID, password, and encryption type (WPA/WPA2, WEP, or none). Scanning the code will prompt the device to connect to the network automatically.
