Frequently Asked Questions

What do the QR code error correction levels (L, M, Q, H) mean?

Error correction enables QR scanning even if the code is smudged or partially obscured: Level L recovers up to 7% damage, M 15%, Q 25%, and H up to 30%.

Do generated QR codes expire?

No. FreeAPI generates static QR codes that embed data directly into the matrix pattern. They never expire and require no external redirection server.
