Is my data sent to a server?▼
No. QR codes are generated entirely in your browser using the qrcode JavaScript library. No data leaves your device.
What is error correction level?▼
Error correction allows a QR code to be read even if partially damaged or obscured. Level L recovers 7%, M 15%, Q 25%, H 30% of data. Higher levels produce denser QR codes.
How much text can a QR code hold?▼
A QR code can hold up to ~4,296 alphanumeric characters. URLs are ideal. Very long text produces dense, harder-to-scan codes.
Can I use a custom color?▼
Yes. Pick any dark and light color. Ensure sufficient contrast for scanners — a dark pattern on a light background works best.
