QR code best practices
Keep contrast high
The code foreground should stay visibly darker than the background so scanners can read it reliably.
Leave a quiet zone
A clean border around the QR code helps scanning software distinguish the code from surrounding design elements.
Choose the right error level
Higher correction helps when a logo or visual overlay interrupts the pattern.
Common use cases
- Wi-Fi sharing for guests and offices
- Digital business cards and contact exports
- Product traceability and packaging links

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.
