How it Works
The QR Generator uses standard 2D barcode encoding rules. It translates your text into a matrix of black and white squares that can be instantly read by smartphone cameras and barcode scanners. The rendering is done dynamically via HTML5 Canvas.
Frequently Asked Questions
Do these QR codes expire?
No. These are static QR codes. Because the actual text or URL is encoded directly into the pattern (and not relying on a shortlink redirect service), the QR code will work forever.
Calculations are verified against standard mathematical and banking benchmarks. Data stays on your device in local memory.
