Question 1

Is QR code generation secure?

Accepted Answer

Yes. QR codes are generated entirely locally in your browser; input content is never uploaded to any server, making it suitable for handling sensitive links or private information.

Question 2

How to choose the error correction level?

Accepted Answer

The higher the error correction level, the easier it is to scan the QR code even if partially damaged or obscured, but the code becomes denser. Use M for regular links; if the QR code will be printed, labeled, or have a logo added, use Q or H.

Question 3

Why does generation fail if the content is too long?

Accepted Answer

QR codes have limited capacity, and higher error correction levels can hold less data. When text exceeds the capacity, generation fails. You can shorten the content (e.g., use a short link) or lower the error correction level and try again.
