(1)Frequently Asked Questions
Do generated QR codes ever expire?▼
No! These are standard static QR codes containing raw payload data (e.g. your URL or WiFi password). They work forever with no redirects or tracking servers involved.
Can I connect to WiFi by scanning a QR code?▼
Yes! Select the "WiFi Network" type, enter your network SSID and password, and scan the QR code with any modern phone camera to join automatically.
Can I download the QR code as vector SVG?▼
Yes! You can download high-resolution PNG images up to 1200×1200 pixels or download infinite-resolution vector SVG files suitable for print.
What is Error Correction Level?▼
QR codes use Reed-Solomon error correction. Levels range from Low (7% recoverable) to High (30% recoverable). Higher levels allow the QR code to be scanned even if part of it is smudged, covered, or printed with a central logo.
Is my WiFi password or contact information sent to your server?▼
Never. The QR code generator runs 100% locally in your web browser. Nothing is ever transmitted to a backend or external service.
