Local QR generator
QR code generator and print check
Turn a URL or text into a QR code and review its error correction, quiet zone, and generated-image scan when supported. Text stays local; URLs are fetched only as needed for the bounded destination check.

Generated result
Scan quality depends on error correction, printed module size, quiet zone, dirt, and damage. Successful generation does not guarantee a distributable print.
Why this is private
- Generation, PNG/SVG export, and re-scan checks run in your browser.
- There is no upload to a QR service, URL shortener, or dynamic QR analytics endpoint.
- A UTM result can be handed to this page through an explicit device-local button.
- Saving is explicit and local; sharing never includes your input.
