QR Code Generator

Anything as text — URLs, plain text, WiFi credentials (use format WIFI:T:WPA;S:MyNetwork;P:password;), vCards (contact cards), phone numbers (tel:+44...), or SMS (sms:+44...?body=hi).

How much of the QR code can be damaged and still be readable. L = 7% (smaller code), M = 15% (balanced), Q = 25%, H = 30% (largest, best for outdoor/worn codes).

SVG scales to any size without blurring — best for print. PNG is smaller and works everywhere online. Use SVG when possible.

No. Static QR codes (like these) encode the data directly — they're permanent. Only "dynamic" QR codes from paid services can expire, because they're really redirects.
