QR Code Generator — Frequently Asked Questions
Everything you need to know about using QR Code Generator.
Do QR codes expire?
Static QR codes (which this tool generates) never expire. The data is encoded directly in the pattern, so it works forever.
What can I put in a QR code?
URLs, plain text, WiFi credentials, email addresses, phone numbers, and more. Each type triggers different actions when scanned.
What's the difference between PNG and SVG output?
PNG is a raster image — great for digital use and printing at a fixed size. SVG is a vector image — it scales to any size without losing quality, ideal for large format printing.
Can I customize the colors?
The tool generates standard black-and-white QR codes for maximum scan reliability. Always ensure high contrast between the code and background.
How do I scan a QR code?
Most modern phones have QR scanning built into the camera app. Just point your camera at the code and tap the notification that appears.
