Frequently asked questions
What is a QR code wallpaper?
A QR code wallpaper is a phone lock-screen or home-screen image with a QR code on it. When someone scans the code with their camera, their phone offers to save your contact details, open your link, or join your Wi-Fi — instantly and without any app.
Is QR Wallpaper Studio free?
Yes. It is completely free to use, with no sign-up and no watermark. You can create and download as many wallpapers as you like.
Is my contact information private?
Yes. Everything runs entirely in your browser. Your details and images are never uploaded to a server or stored anywhere — the QR code and wallpaper are generated on your own device.
Do people need an app to scan the QR code?
No. The built-in camera on iPhone and Android recognises the QR code automatically. For contacts it uses the standard vCard format, so the phone shows an "Add Contact" prompt with no extra app.
What can the QR code contain?
A full contact card (name, phone, email, company, address, website and social links), a website link, a Wi-Fi network, plain text, or a map location.
Does it work for both iPhone and Android?
Yes. You can export the wallpaper at the exact resolution for iPhone, iPhone Pro Max, and common Android sizes, and the QR formats are supported by both platforms.
