You can download the result as SVG or PNG, making it useful for both print and digital applications."},{"question":"How do I use QR Code Generator?","answer":"Enter your content — a URL, text, WiFi network details, or other data — and a QR code is generated instantly. Customize the size and error correction level, then download as SVG or PNG."},{"question":"Is QR Code Generator free?","answer":"Yes. This tool is free to use with immediate access—no account required."},{"question":"Does QR Code Generator store or send my data?","answer":"No. All processing happens entirely in your browser. Your data never leaves your device — nothing is sent to any server."},{"question":"What is the difference between SVG and PNG downloads?","answer":"SVG is a vector format that scales to any size without losing quality, making it ideal for print materials.
