WiFi QR Code Generator

Giving guests the Wi-Fi password is a small friction that adds up. You spell it out, they mistype, you repeat, they mistype again, and eventually everyone gives up or you change to the password on a sticky note. A Wi-Fi QR code eliminates the back-and-forth: print it once, stick it on the wall, and anyone with a modern phone points their camera at it and taps Connect. No typing, no errors, no password gymnastics.

The format behind Wi-Fi QR codes is a simple string standard that every major phone OS recognizes. This generator builds the string correctly, handles escape characters for special symbols in your password, supports WPA/WPA2, WPA3, and WEP encryption types, and marks hidden networks with the right flag. Paste your SSID and password, pick your encryption, and the QR updates live in the preview.

Once you are happy, download as PNG for digital sharing or SVG for print-quality signage. Common use cases are home guest Wi-Fi stickers, cafe and restaurant table cards, hotel room hospitality, Airbnb welcome booklets, office guest networks, and conference common areas. Because the generator runs entirely in the browser, your SSID and password never leave your device — no server logs your credentials. Print it once and your network is hospitable without anyone needing to remember a 20-character password.

Wi-Fi QR codes encode a specific string format originally defined by Wi-Fi Alliance in the Device Provisioning Protocol family. The payload looks like:

WIFI:T:WPA;S:MyNetwork;P:mypassword;H:false;;

Where:
- T: encryption type (WPA for WPA/WPA2/WPA3, WEP for WEP, nopass for open networks)
- S: SSID (network name)
- P: password (omitted for open networks)
- H: true for hidden SSID, false or omitted otherwise
- ;;: trailing double semicolon marks the end

Special characters within the SSID or password must be escaped with a backslash: semicolons, commas, double quotes, colons, and backslashes themselves. This generator handles escaping automatically, which matters because many passwords contain special characters. Unicode and emoji in SSIDs are supported; modern phones decode them correctly.

iOS (since iOS 11) and Android (since Android 10 natively; earlier versions via apps) support Wi-Fi QR codes out of the box. You point the camera at the code, tap the notification or banner, and the phone joins the network. Older Android devices need a third-party scanner app. WPA3 is increasingly common; if your router supports it, select WPA3 in the tool. For maximum compatibility select WPA which covers WPA, WPA2, and WPA3 devices. WEP is supported for legacy networks but you should upgrade — WEP is insecure. Open networks set encryption to nopass.

Typing a Wi-Fi password is a friction every guest hits. Pre-configured guest portals work but require networking expertise and hardware support. Writing the password on a chalkboard is low-tech but error-prone. A Wi-Fi QR code solves both problems with no extra hardware — print once, guests scan, they are on. This generator produces standards-compliant strings, handles special characters, supports hidden and open networks, and runs entirely in your browser so your password stays private. It is the simplest hospitality upgrade you can make.
