Zero Tracking, No Expiration & 100% Client-Side Rendering

Our generator creates 100% static, standard ISO/IEC 18004 QR codes generated locally in your browser canvas.
Your encoded data, URLs, and Wi-Fi credentials are never stored, logged, or routed through any proxy server. Your QR codes will remain scannable forever without unexpected fees, expiration gates, or third-party dependencies.

Frequently Asked Questions
Is my data transmitted or tracked?
No. All QR code generation is performed 100% locally in your web browser using client-side JavaScript. No URLs, text, or tracking identifiers are ever sent to any remote server.
Does a QR code encrypt my information?
No. A QR code is an optical data representation, not an encryption method. Anyone with a smartphone camera or scanner can read the text or URL encoded in the code.
What error correction level should I choose?
Level M (15% recovery) is ideal for most digital and print uses. Level H (30% recovery) provides maximum durability if the code may get smudged, worn, or partially obstructed.
What formats can I download?
You can download your generated QR code as a raster PNG file for immediate sharing or as a scalable vector SVG file for crisp print and graphic design work.
