Free QR Code Generator — No Tracking, No Expiry

How do I make a Wi-Fi QR code for guests?

Choose Wi-Fi, enter the network name, password and security type (usually WPA/WPA2), then print the PNG or SVG as a small card for the table or reception. Guests scan it with their phone camera and join without typing the password.

Can I put a QR code on my business card?

Yes. Choose Contact (vCard), fill in name, phone, email and company, and download the SVG so it stays sharp in print. Keep it at least 2 cm wide with the white margin intact so phones read it reliably.

Do these QR codes expire or track scans?

No. The code encodes your content directly, so there is no short link in the middle that could expire or count scans. Once downloaded it works forever, offline, with no dependency on this site.

Is my data sent anywhere?

No. The QR is generated inside your browser tab with a JavaScript library. Your link, Wi-Fi password or contact details are never uploaded, stored or logged.

PNG or SVG — which should I choose?

PNG for websites, slides and social posts. SVG is vector, so it stays perfectly sharp on posters, packaging and anything printed large.

Why add a logo and higher error correction?

A centre logo covers part of the code. Error-correction level H can restore up to 30% of the pattern, so pick Q or H whenever you place a logo, then test the result with a phone.

Is the Wi-Fi QR code safe to print?

The network password is encoded in plain text inside the code, exactly as the Wi-Fi standard requires. Anyone who scans it joins the network, so only display it where you would share the password anyway.
