Frequently asked questions
Which format is best for printing?
SVG or PDF, because they are vector and stay sharp at any size. For PNG, use at least 1000 px.
How big should a printed QR code be?
At least 2 × 2 cm for close scanning; as a rule of thumb, the size should be about one tenth of the scanning distance.
Why was my code marked "not verified"?
Our decoder couldn't read the rendered code. Increase contrast, reduce the logo size or use simpler dot styles.
