About QR codes

A QR (Quick Response) code encodes data as a pattern of black and white squares that any smartphone camera can scan instantly. This generator creates QR codes for URLs, text, email, phone, SMS, and Wi-Fi — all processed in your browser, nothing sent to a server.

Best practices for printable QR codes

Print at least 2 cm x 2 cm for reliable scanning from 20-30 cm away. Maintain high contrast (black on white works best). Leave a quiet zone (white border) around the code. Test on multiple devices before printing in bulk.

QR code error correction

QR codes have built-in error correction. Even if up to 30% of the code is damaged or covered, it can still be read. This is how logos are overlaid on branded QR codes without breaking them.

Frequently asked questions

What can a QR code contain?

URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi credentials, and contact cards. URLs are the most common use case.

How do QR codes work?

A camera decodes the pattern of squares into text or a URL. Built-in error correction means up to 30% of the code can be damaged and it still reads correctly.

Can I customize the color of a QR code?

Yes. Use the color pickers above to change foreground and background colors. Keep high contrast between them. Dark modules on a light background scan most reliably.
