What can a QR code encode?

A QR code can encode any text — URLs, plain text, email addresses (mailto:), phone numbers (tel:), Wi-Fi credentials, and more. Most smartphones scan QR codes natively without a separate app.

How large should my QR code be for print?

For printed materials, use at least 300×300 px at 300 DPI. A larger QR code is easier to scan from a distance. The minimum printable size is roughly 2×2 cm.

Are my QR codes stored anywhere?

No. QR codes are generated entirely in your browser using the qrcode library. Nothing you enter is sent to a server.

What can I encode in a QR code?

Any text string — including URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages, Wi-Fi credentials, and vCard contact details. Most smartphone cameras can scan QR codes natively without a third-party app.

What size QR code should I use for print?

For printed materials, generate at least 300×300 px and print at 300 DPI or higher. The minimum physical size for reliable scanning is around 2×2 cm. Larger and denser content (longer URLs) requires a bigger code to remain scannable.
