Common Mistakes to Avoid

✗
Low color contrast: Using light colors like yellow or light gray on white backgrounds makes it hard for camera lenses to recognize the code modules.
✗
No link verification: Printing a code containing a broken URL or a spelling mistake will break the scanner routing. Always test scan the preview on your screen.
✗
Printing on glossy surfaces: Laminating or printing on highly reflective paper creates glare that blocks camera sensors. Always choose a flat, matte paper finish.
✗
Oversized URL payloads: Pasting extremely long links increases the density of the square grid, making it difficult for older phone cameras to parse.

Frequently Asked Questions

No. These are static QR codes where the data is written directly into the pattern, so they will work forever as long as your link remains active.
Yes, you can change the colors to match your branding. Just make sure the foreground color is dark and the background is light so cameras can scan it.
High-resolution PNG is perfect for standard printing on business cards and posters, while SVG vectors are ideal for large banners.
No, static QR codes don't support tracking because the data is written directly into the image. If you need analytics, use a URL shortener with scan tracking before generating the code.
This is usually caused by low contrast between the squares and the background, a blurry image, or holding your phone too close to focus.
