🤔 How Does This Work?

Our QR Code Generator creates QR codes entirely in your browser using the qrcode.js library:

  • For URLs: encodes the full URL directly
  • 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
  • Download creates a PNG image file from the canvas

All QR codes are generated locally — no data is sent to any server. Your WiFi passwords and contact information stay completely private.

✅ Trusted Tool
The 365tool.net QR Code Generator runs entirely in your browser using open-source JavaScript. Your data — including WiFi passwords and contact information — is NEVER sent to any server. Completely private, completely free. No sign-up needed.
❓ 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!
