常见问题

What can I encode in a QR code?

You can encode URLs, plain text, WiFi credentials (WIFI:T:WPA;S:network;P:password;;), phone numbers, email addresses, and more. URLs are the most common use case.

What size should I generate?

400px is ideal for most digital uses. Choose 800px if you plan to print the QR code. 200px is fine for small web widgets.

Will dark mode colors still scan?

Yes, as long as there's sufficient contrast between the foreground and background colors. The default dark-on-dark theme works well with most scanners.
