Is my content uploaded?

No—QR is rendered locally; input never hits a server.

Depends on length and error level—URLs and short text are fine; very long text needs shorter URLs first.

PNG—ready for docs, posters, or print.

The image is static; URL links depend on your target site, not us.

Raise error correction, increase size, avoid blur when printing.

Use our dedicated Wi-Fi QR tool for standard WIFI: payloads.
