Why a QR code will not scan
Codes can become difficult to read when printed too small, stretched, blurred or placed on a low-contrast background.
Why this happens
Codes can become difficult to read when printed too small, stretched, blurred or placed on a low-contrast background.
What to try first
Keep the code square and leave a clear border. Test the actual printed or displayed version, not only the original PNG on your screen.
Try it on a fresh copy
- Paste the complete link or enter the short text the code should contain.
- Generate the code and download the PNG.
- Scan that saved image with another device. If it is going on a poster, test a print at the intended size too.
How to tell whether it worked
Scan the downloaded PNG with another device before printing or sharing.
