Frequently Asked Questions

What is a QR code?: A QR (Quick Response) code is a two-dimensional barcode that can store text, URLs, WiFi credentials, contact information, and more. Smartphone cameras can scan them to instantly access the encoded content.
Are my QR codes secure and private?: Yes! This generator works entirely in your browser - no data is sent to any server. Your WiFi passwords, contact details, and other information never leave your device.
What size should I choose for my QR code?: For screens and web use, 256px works well. For printing, use 512px or download the SVG version which scales to any size without losing quality.
What's the difference between PNG and SVG?: PNG is a pixel-based image format ideal for screens and documents. SVG is a vector format that can be scaled to any size without becoming blurry - perfect for printing large posters or high-quality materials.
Do QR codes expire?: No! QR codes created here are static and permanent. They encode the content directly in the code itself, so they'll work forever as long as the linked content (like a website) remains available.
