Frequently Asked Questions

Do these QR codes expire?

No, never. Many commercial QR services create 'dynamic' links that redirect through their servers so they can bill you a monthly fee later. Our tool creates permanent, static QR codes that encode your data directly into the matrix pattern. They work forever with zero dependencies.

How does the Wi-Fi QR code work?

When a smartphone camera scans a Wi-Fi QR code, iOS and Android automatically recognize the network credentials and prompt the user to join the Wi-Fi network instantly without manually typing the password.

Which format should I download for printing?

For business cards, flyers, and physical signs, download the vector SVG format. SVG graphics can be scaled to billboard size without any loss of sharpness or pixelation. For websites and digital sharing, PNG at 512px or 1024px is ideal.

Is my data safe and private?

Yes. All matrix calculations, rendering, and file exports are executed strictly inside your local browser. Your Wi-Fi passwords, contact details, and URLs are never sent to any server or recorded in any database.
