QR code best practices
Keep contrast high
The foreground should stay clearly darker than the background. Stylish low-contrast codes look good in a mockup and fail in real lighting.
Leave a quiet zone
A clean border around the QR code helps scanners separate the pattern from a poster, package, menu, slide, or busy background.
Choose the right error level
Higher correction helps when printing, cropping, damage, or a small logo interrupts part of the pattern.
Test the final placement
Scan the code after it is printed, exported, compressed, or placed in the actual design. The preview is not the same as the physical use case.
Common use cases
- Wi-Fi sharing for guests and offices
- Digital business cards and contact exports
- Product traceability and packaging links
- Payment and donation entry points
QR code FAQ
What does error correction mean?
It is the amount of damage or obstruction a QR code can tolerate before scanners stop reading it reliably.
Does the generated QR code expire?
Not by itself. The QR code simply encodes the content you provide, so it remains valid as long as the underlying destination still works.
Can these QR codes be used commercially?
Yes. The generated images are plain output files without forced branding overlays.
How do I create a Wi-Fi QR code?
Use a payload format such as WIFI:T:WPA;S:MyNetwork;P:MyPassword;; and generate the code from that string.
Can I change the destination after printing?
Only if the QR code points to a URL that you control and can redirect. A static QR code that encodes final text or a final URL cannot be edited after printing.
What size should a printed QR code be?
It depends on scan distance, print quality, and encoded data length. For small close-range use, test at the final size before ordering a full print run.
