🤔 How Does This Work?

For phone numbers: uses the tel: URI scheme (tel:+94712345678)
For email: uses the mailto: URI scheme with optional subject
For WiFi: uses the WIFI: format (WIFI:T:WPA;S:NetworkName;P:Password;;)
The QR code is rendered on an HTML canvas element

❓ FAQ
How do I scan a QR code?▼
Open your phone's camera app and point it at the QR code — that is it! Most modern smartphones (iPhone 6 and later, Android 8 and later) scan QR codes automatically with the camera app. You do not need any special QR scanner app.
Can I use the QR code for commercial purposes?▼
Yes! QR codes generated on 365tool.net are free to use for any purpose including business, commercial, and personal use. No attribution needed.
How long does a QR code last?▼
QR codes themselves never expire. They are just encoded data. However, if the QR code links to a URL and that URL goes offline, the QR code will stop working. For permanent use, link to stable, long-lasting URLs.
How much data can a QR code hold?▼
A QR code can hold: up to 4,296 alphanumeric characters, 7,089 numeric digits, or 1,817 Chinese/Japanese characters. For URLs, keep them short for best scanning reliability. Shorter data = simpler QR code = easier to scan.
What size should I print a QR code?▼
For reliable scanning: minimum 2.5 cm x 2.5 cm (1 inch). For posters: at least 5 cm x 5 cm. For billboards: much larger. Always test scan your printed QR code before mass printing!
