How do you make a WiFi QR code?

Enter the network name, the password and the security type, then download the PNG or SVG. Scanning it joins the network without typing anything. The credentials are encoded as plain text inside the code, so anyone who scans it can read the password — use a guest network in public spaces.

How to display your WiFi QR code

Drop it on a table tent, sticker, or framed card at reception, on tables, or near the entrance.

Their phone joins automatically — works on iOS camera app and Android. No typing, no mistakes.

Why use a WiFi QR code?

WiFi QR codes are the fastest way to share internet access with guests, customers, or visitors. Instead of reading out a complex password — with uppercase letters, numbers, and symbols — guests simply point their camera at the code and connect in one tap.

Hotels, cafés, restaurants, Airbnb hosts, coworking spaces, and offices all use WiFi QR codes. A single laminated card on reception or a sticker on each table eliminates the most common guest frustration: "What's the WiFi password?"

The QR code is generated using the standard WIFI: format, which is natively supported by the iPhone camera app (iOS 11+) and the Android camera app — no additional app download required.

Frequently asked questions

Does the WiFi QR code expire?

No. QRLifetime generates static QR codes that are encoded directly into the image. They work forever, even without an internet connection, and require no subscription.

Is my WiFi password safe?

Yes. Your WiFi credentials are never sent to any server. The QR code is generated entirely in your browser using JavaScript. Only the people who scan the printed QR can join your network.

What size should I print my WiFi QR code?

For a table tent or A6 card, 5×5 cm (2×2 in) is sufficient. For an A4 poster on a wall, use 10×10 cm (4×4 in) at minimum. Download at 1024 px or 2048 px for sharp prints.

Does it work with iPhone and Android?

Yes. The WiFi QR format is supported natively by iOS camera app (iOS 11+) and Android camera app. No special app needed.

Technical reference

WiFi QR code: format and compatibility

A WiFi QR code encodes the network credentials as plain text in the form WIFI:T:WPA;S:network;P:password;H:false;; — anyone who scans it can read the password.

Security type	Encoded as	Native support
WPA / WPA2	T:WPA	iOS 11+, Android 10+
WPA3	T:WPA	Unreliable — many devices fail to join
WEP	T:WEP	iOS 11+, Android 10+ (obsolete, avoid)
Open, no password	T:nopass	iOS 11+, Android 10+
Hidden SSID	H:true	Android 10+; unreliable on iOS

The password is stored in clear text inside the code. For a public space, use a guest network rather than your main one.

Minimum QR code size by scan distance

The 10:1 rule: divide the distance the code will be scanned from by 10 to get its minimum printed side length. Below this, phone cameras fail to lock on.

Scan distance	Minimum size	Typical use
10 cm	1 cm	Product label, business card
30 cm	3 cm	Menu, flyer, packaging
1 m	10 cm	Poster, shop window
3 m	30 cm	Wall display, exhibition stand
10 m	100 cm	Billboard, building signage

Add a quiet zone of at least 4 modules around the code, and print from SVG rather than PNG for anything above A5.
