Fix a code that will not scan

Work through the common reasons a QR code will not scan: low contrast, a code printed too small, too little quiet zone or a heavy design.

If a code does not scan, the cause is almost always the print, not the code. Work through these in order.

Test it in our QR code scanner to confirm the image itself reads.
Open the code's Design tab and watch the print check. If it shows This code may not scan, apply the suggested fix.
Raise the contrast: dark dots on a light background read best.
Print it larger and keep the clear space (quiet zone) around it.
Make the logo smaller, or choose square dots and a higher error correction level.

Good to know

A screen with low brightness or a scratched print can stop a scan. Try a clean copy on paper.
