FAQ
What is error correction?
QR codes have built-in error correction that lets them be read even if partially damaged or obscured. Level L (7%) is smallest, H (30%) is most resilient but produces a denser code.
Is my data sent anywhere?
No. QR code generation runs 100% in your browser using JavaScript. No data leaves your device.
What's the maximum data size?
QR codes can store up to ~4,000 alphanumeric characters. For best scan reliability, keep URLs under 300 characters and text under 500.
