关于此工具
Generate a QR code that automatically connects any phone to your Wi-Fi network when scanned. Supports WPA/WPA2/WPA3, WEP, and open networks. Special characters in your SSID or password are escaped according to the official Wi-Fi QR text spec, so the code works even for networks with quotes, semicolons, or backslashes in their credentials. aukimi Vectra的一部分.

How to create a Wi-Fi QR code
Generate a scannable Wi-Fi QR code with the official Wi-Fi Network text format — no typing needed when guests connect.
- 1
Enter your SSID
Type the exact network name as it appears on your router. The tool escapes semicolons, colons, quotes, and backslashes for you.
- 2
Enter the password
Leave blank and pick "None" if your network is open.
- 3
Choose encryption
WPA (covers WPA/WPA2/WPA3 — pick this unless your router is very old), WEP (legacy), or None (open network).
- 4
(Optional) Mark as hidden
Check "Hidden network" if your SSID is not broadcast.
- 5
Customize and download
Pick colors, optionally add a logo, then download PNG for screen or SVG for print.
常见问题
Which phones can scan a Wi-Fi QR code?
All modern iPhones (iOS 11+) and Android devices (Android 10+) scan Wi-Fi QRs natively from the camera app. Older Android phones may need Google Lens or a QR reader app. iOS recognizes the format from the official Wi-Fi Network string (WIFI:T:WPA;S:SSID;P:PASSWORD;;).
Is WPA3 supported?
Yes — the Wi-Fi QR spec treats WPA, WPA2, and WPA3 as the same authentication type (use "WPA"). Your phone negotiates the highest version the router supports. Open networks use "nopass" and omit the password entirely.
How do I create a hidden-network QR?
Toggle the "Hidden network" option. This flags the SSID as non-broadcasting in the QR string (`H:true`), so phones know to query the network explicitly when connecting.
Should I add my logo to a Wi-Fi QR code?
If you are printing it for a café/Airbnb/office, a small center logo is a nice branding touch — our generator bumps error correction to level H automatically so the QR remains reliable. Avoid logos larger than 25% of the QR area.
Does the QR store my password somewhere?
No. The QR is encoded and rendered entirely in your browser — no upload, no server call, no tracking. The code itself contains the password in plain text (that is how Wi-Fi QRs work universally), so anyone who scans it joins your network. Treat the printed QR as you would treat the written password.
Can I generate one for a guest network?
Yes — that is the most common use. Configure your router's guest Wi-Fi with a dedicated SSID and password, generate a QR for those credentials, and print it. Guests scan, connect, and never see your main network.
