Question 1

Will the QR code expire?

Accepted Answer

No. The content is encoded directly into the image — no server, no redirect link — so it keeps working after printing or saving.

Question 2

Is my content uploaded anywhere?

Accepted Answer

No. Encoding, preview and export all run locally in your browser, and it keeps working offline.

Question 3

The QR code stops scanning after I add a logo. What should I do?

Accepted Answer

Set error correction to Q or H, keep the logo under 25% of the code area, and scan it with a real phone before downloading.

Question 4

How much content fits?

Accepted Answer

Aim for under 300 characters. More content means denser modules, which are harder to scan from a distance or in low-resolution print.
