What can I encode in a QR code?

Any text content: website URLs, Wi-Fi network credentials, phone numbers, email addresses, contact cards (vCard), geographic coordinates, or plain text messages.

What size should I make my QR code?

For print use, a minimum of 2cm × 2cm (about 236×236 pixels at 300 DPI) is required for reliable scanning. Larger is better. For digital display, 256×256 pixels is a good starting point.

Can I use a custom logo in the QR code?

The standard generator produces clean QR codes without an embedded logo. QR codes with logos require careful error correction tuning to remain scannable.
