Frequently Asked Questions

Is the QR code generator really free?
Yes, our QR code generator is completely free and requires no registration. You can create and download unlimited QR codes – no watermarks or hidden costs.
Can I add a logo to my QR code?
Yes, you can upload your own logo or image. The QR code is automatically generated with increased error correction to ensure it remains scannable. Make sure the logo isn't too large (max 30% of the area).
What formats can I download?
You can download your QR code as PNG (ideal for web and digital media) or SVG (losslessly scalable, perfect for print). Both formats are suitable for professional applications.
How does the WiFi QR code work?
The WiFi QR code contains the network name (SSID), password, and encryption type. When someone scans the code with their smartphone, they can connect to the WiFi with one click – without manually entering the password.
What is error correction?
Error correction determines how much of the QR code can be damaged or covered while still being readable. Higher levels (Q, H) are important when adding a logo or when the code is printed. Lower levels (L, M) create more compact codes.

Código QR creado – ¿pero quién ve tus datos?

Los códigos QR estáticos muestran todo abiertamente. SilentLink funciona diferente: contacto sin compartir datos personales. Ideal cuando desconocidos necesitan contactarte – pero no deberían saber todo.
