QR Print Proof

QR print checker

Contrast, quiet zone, and a millimetre width for the symbol you type.

What it does: Builds a QR from your text, checks contrast and quiet zone, and estimates print millimetres.

What it does not: Not a lab scan guarantee. No logo or rounded modules. Download unlocks even if read-back fails — print and scan yourself.

Limits: Work stays in this browser. Prefer dark modules on a light background.
