Frequently Asked Questions
What types of data can I encode?
You can encode URLs, plain text, WiFi credentials, vCard contact info, emails, phone numbers, and any other text-based data in a QR code.
What is error correction?
Error correction allows QR codes to be scanned even if partially damaged or dirty. Higher levels (H=30%) provide more resilience but create denser codes.
Can I customize colors?
Yes, you can change both foreground (pattern) and background colors. Ensure sufficient contrast for reliable scanning.
What's the difference between PNG and SVG?
PNG is a raster format best for digital use. SVG is vector format that scales infinitely without quality loss, ideal for printing.
Is my data sent to a server?
No, QR codes are generated entirely in your browser. Your data never leaves your device.
