Frequently Asked Questions

Find Quick Answers

What data can I encode in a QR code?

You can encode any text data including URLs, plain text, contact information (vCard), WiFi credentials, email addresses, phone numbers, and more.

What's the difference between error correction levels?

Error correction allows QR codes to be scanned even if partially damaged. L (Low) recovers 7% of data, M (Medium) 15%, Q (Quartile) 25%, and H (High) 30%. Higher levels create denser QR codes but are more readable when damaged.

Is my data secure when generating QR codes?

Yes, all QR code generation happens entirely in your browser using JavaScript. Your data never leaves your device or gets sent to any server.

What file formats are available for download?

You can download your QR code as PNG (best for web), JPEG (compressed), or SVG (vector format for scaling without quality loss).

Can I use the generated QR codes commercially?

Yes, all QR codes generated with this tool are free to use for personal or commercial purposes without attribution.
