Technical notes

Wi-Fi QR codes use the WIFI:T:WPA;S:NetworkName;P:Password;; format; scanning it prompts phones to join the network. Characters such as ; , : \ in the SSID or password are escaped with a backslash.

A vCard carries a contact card (name, phone, email, company) and is produced with VERSION:3.0. The more compact MECARD format is also available; both are recognized by most phone camera apps.

The error-correction level L(7%), M(15%), Q(25%), H(30%) sets how much of the data can be recovered. A higher level survives more damage or a logo overlay but increases the module count; choose Q or H if you place a center logo.

As the content grows, the QR 'version' (matrix size) grows and modules shrink. Shortening long URLs yields larger modules that scan more easily from a distance.

All generation runs in your browser; the content is never sent to a server. A QR code itself is neither safe nor dangerous, only a carrier — see are QR codes safe for details.

Frequently asked questions

No. This tool makes static QR codes; the content lives inside the code and works indefinitely. It relies on no redirect server.
