WiFi QR Code Generator — Instant WiFi QR for Guests
Stop telling guests your WiFi password one letter at a time. Generate a QR code they can scan to connect automatically — no typing, no mistakes, no frustration. Works on iOS 11+ and Android 10+. Free, no signup, runs entirely in your browser.
Sharing WiFi has always been awkward — reading out a 16-character password, watching someone mistype it twice, repeating the process for every new guest. A WiFi QR code solves this completely. Your guests point their phone camera at the code and the phone asks if they want to join. One tap and they are connected. This works at home with family and friends, in a coffee shop where you have a dedicated guest network, in an Airbnb where you can print the code and frame it on the desk, in hotel rooms, conference rooms, restaurant tables, and pop-up events. Just enter your network name and password below, download the PNG, and print it wherever you need it. One important security note: the QR code encodes your WiFi credentials in a format any QR reader can decode. Only share the printed code with people you trust, and consider using a separate guest network if you are displaying it in a public or semi-public space.
Enter your WiFi network name to generate QR code
How Does a WiFi QR Code Work?
A WiFi QR code encodes your network credentials using the WIFI: URI scheme — a standard format that iOS and Android cameras recognize out of the box. The string looks like WIFI:T:WPA;S:MyNetwork;P:MyPassword;; and is embedded inside a standard QR code image.
When a phone camera detects this pattern, it automatically offers to join the network. On iPhone (iOS 11+), you will see a banner at the top of the camera view. On Android 10+, the camera app shows a pop-up. No third-party app is needed on any modern phone.
The QR code is generated entirely in your browser using the open-source qrcode library. Your password is never sent to any server.
WiFi QR Code Use Cases
- Home guests — Print and place on the fridge or by the router. Visitors connect themselves without interrupting you.
- Coffee shops and restaurants — Display on table cards or at the counter. Guests connect instantly and the password stays private from competitors.
- Airbnb and hotels — Frame the QR code on the desk or nightstand. Guests check in and connect in seconds, reducing support messages.
- Offices and conference rooms — Put the QR code on the wall or TV frame. Visitors and contractors join the guest network without asking anyone.
- Events and pop-ups — Include on printed programs or signage. Attendees connect before your talk even starts.
WiFi Encryption Types
WPA / WPA2 (most common)
The current standard for home and business routers. If your router was purchased in the last ten years, it almost certainly uses WPA2. Choose this option unless you know otherwise. WPA3 networks are also compatible with the WPA selection.
WEP (legacy — avoid if possible)
An older encryption standard from the late 1990s. WEP has known security vulnerabilities and most modern routers no longer support it. Only select this if your router is old and specifically uses WEP. Consider upgrading to a WPA2 router.
None / Open network
For networks with no password at all. Common for free public WiFi in airports, libraries, and some cafes. No password field is needed — the QR code encodes only the network name.
Printing Your WiFi QR Code
For reliable scanning, print the QR code at a minimum size of 2 cm x 2 cm (about 0.8 inches). Smaller than that and some cameras will struggle to read all the modules, especially on dense codes with long passwords. A 5 cm x 5 cm (2 inch) square is a safe target for most print materials.
High contrast black on white is the most reliable combination. Avoid colored backgrounds, gradients, or placing the QR code over a photograph. Always test scanning from the actual printed output before distributing widely — printer quality and paper finish can affect scan reliability.
For durability, consider laminating the printed sheet or using a photo frame with a glass front. This protects the code from moisture and fading, making it last for years without reprinting.
Frequently Asked Questions
Is it safe to share my WiFi password in a QR code?▾
A WiFi QR code encodes your password in a readable format within the QR image — anyone who scans or decodes the image can extract it. For home networks shared with guests, this is perfectly fine. Avoid displaying the QR code in public places where untrusted people could scan it. For offices and businesses, use a dedicated guest network with a separate password before creating the QR code.
Does WiFi QR code work on iPhone and Android?▾
Yes. iOS 11 and later supports WiFi QR codes natively through the Camera app — just point it at the code and tap the notification to join. Android 10 and later handles it the same way via the built-in camera. On older Android versions, Google Lens or a third-party QR scanner app will work. The WIFI: URI scheme is a widely adopted standard.
What WiFi encryption types are supported?▾
This generator supports WPA/WPA2 (the most common type for home and office routers), WEP (an older legacy standard), and open networks with no password. Choose WPA/WPA2 unless your router specifically uses WEP or has no password set.
Can I use this for a hidden network?▾
Yes. Check the 'Hidden network' checkbox if your router is configured not to broadcast its SSID. The QR code will still encode the network name correctly, and phones will attempt to connect using the hidden SSID. Note that the person scanning must have their phone in range of the router for the connection to succeed.
Is this WiFi QR code generator free?▾
Yes — completely free. There is no signup, no watermark, and no limit on the number of QR codes you can generate. Everything runs in your browser and your WiFi credentials are never sent to any server.
