Frequently Asked Questions
Do these QR codes expire?
No. These are standard static QR codes encoding the raw text, URL, or Wi-Fi credentials directly into the module matrix. They contain no redirect intermediaries and never expire.
Can any smartphone camera scan these QR codes?
Yes. The generator produces standard ISO/IEC 18004 compliant QR codes readable by built-in iOS and Android camera apps without extra software.
Are my Wi-Fi passwords or URLs transmitted anywhere?
No. The QR matrix is calculated entirely in browser JavaScript and rendered onto an HTML5 canvas. No data is sent over the internet.
What error correction level is used?
The engine implements standard Reed-Solomon Error Correction Level L (recovering up to 7% damaged or obscured codewords), ensuring clean, fast-scanning codes.
What image format is downloaded?
The generator exports clean, high-resolution PNG image files with standard quiet zones that are ready for printing on flyers, menus, or digital displays.
