Is my WiFi password safe in this generator?

Yes — and this is the whole point of the tool. The QR code is encoded by JavaScript running in your browser. Your SSID and password are never transmitted, logged or stored anywhere. You can load this page, go offline, and the generator still works.

How does a WiFi QR code work?

It encodes your network details in the standard WIFI:T:WPA;S:name;P:password;; format that iOS and Android cameras understand natively. Guests point their camera at the code and tap “Join network” — no typing, no reading your password aloud.

Do these QR codes expire or have scan limits?

Never. This generates static QR codes — the content is baked into the pattern itself. There is no redirect server, no account, no expiry and no scan limit, unlike “free” dynamic QR services that route scans through their domain and can break or paywall later.

PNG or SVG — which should I download?

PNG (pick 512px or 1024px) is right for documents, slides and most printing. SVG is a vector — infinitely scalable with tiny file size — ideal for professional printing, posters, or embedding in design tools like Figma and Illustrator.

What does the error correction setting do?

QR codes carry redundancy so they scan even when partially damaged or obscured. Medium (~15% tolerance) suits screens. Choose Quartile or High for printed codes that may get scratched, folded or dirty — the pattern gets denser but sturdier.

Why does my QR code fail to scan?

The usual causes: too little contrast with the background, printed too small (keep it at least 2×2 cm for close scanning), or too much content making the pattern too dense. Keep URLs short, print with white background, and test-scan before mass printing.

Can I make a QR code for a hidden WiFi network?

Yes — tick “Hidden network”. The code then includes the H:true flag, which tells phones to connect without the network appearing in scan lists.

Generate QR codes that never phone home

Pick a tab — Website URL, WiFi network or plain text — and the QR code renders instantly as you type. Everything is encodedon your device: unlike most online generators, nothing you enter is sent to a server, which matters most for the WiFi tab, because a WiFi QR code contains your actual password. Typing your network password into a random website's form is exactly the kind of habit this tool exists to replace.

Static codes: no expiry, no tracking, no ransom

Many “free” QR services generate dynamic codes that redirect through their servers — so they can track every scan, and when the free trial lapses, your printed codes die. Everything made here is a static QR code: the URL, text or WiFi credentials live inside the pattern itself. It will scan identically in twenty years, works with zero internet on the scanning phone (for WiFi and text codes), and nobody — including us — can count, intercept or expire your scans.

Making a WiFi QR code for guests

Enter your network name and password, pick your security type (almost every modern router is WPA/WPA2/WPA3), and download the PNG. Both iPhone and Android cameras recognise WiFi codes natively — guests point, tap, and they're connected. Print it for the guest room, café counter, office reception or Airbnb welcome book. If you rotate your password, just regenerate — it takes ten seconds and costs nothing.

Print quality tips

Use SVG for print shops and posters — it scales without pixelation. Keep at least a small white margin around the code (the tool bakes one in), maintain dark-on-light contrast, and bump error correction to Quartile or High for codes that live outdoors or get handled. Test with both an iPhone and an Android before printing a hundred table tents.
