Why the scan check matters

A logo covers modules in the centre of a QR code. This generator uses high error correction, preserves a four-module quiet zone, limits the logo footprint and decodes the finished canvas locally before enabling download. Passing here is useful but does not replace testing the final printed size, material and lighting.

This creates a static QR code only. TNAADO does not host redirects, track scans or upload your content or logo.
