FAQ

Häufig gestellte Fragen

Do the QR codes generated here expire?
No! The QR codes created with this tool are static codes that encode your data directly into the pixel pattern. They do not rely on external redirection services and will work forever.
Can I generate a Wi-Fi QR code so guests can connect automatically?
Yes! Switch to the Wi-Fi tab, enter your network name (SSID) and password, and choose your encryption type (WPA/WPA2). Guests can simply scan the code with their smartphone camera to connect instantly.
Can I download the QR code as a vector SVG for printing?
Yes. You can download both high-resolution PNG format and clean vector SVG format, which scales infinitely without blurriness for large billboards and print media.
Is my Wi-Fi password or personal data saved?
No. The QR matrix is calculated entirely in client-side JavaScript on your machine. Nothing is ever sent to a server or recorded.
