How to use the QR Code Generator
- Choose what the QR code should contain: a link, text or Wi-Fi login.
- Fill in the content and pick error correction and size.
- Download as PNG for print or chat, or SVG for sharp scaling.
How it works
QR codes store data in a grid of modules with Reed-Solomon error correction, so they still scan when partly damaged or covered by a logo.
Higher error correction makes the code denser but more robust. Wi-Fi codes use the standard WIFI:T:WPA;S:name;P:password;; format that phone cameras recognize.
Frequently asked questions
Do these QR codes expire?
No. The code contains your data directly, so it works forever and does not depend on any service.
Can I put my logo in the middle?
Yes — choose High or Max error correction, then overlay a small logo (under ~20% of the area) in an image editor.
Is my Wi-Fi password sent anywhere?
No. The QR code is generated entirely in your browser.
