How to use Wi-Fi QR Code
- Enter the network name exactly as it appears on your router or phone.
- Choose the network security and enter its password. Open networks need no password.
- Turn on Hidden network name only if the network does not broadcast its name.
- The code updates as you change the fields. Download the image and scan it with a phone before sharing.
Example: Wi-Fi QR Code
Put guest network details on a sign without asking visitors to type the password.
Options
- Network security
- WPA or WPA2 personal is the default. Choose WEP only for a WEP network, or Open network for one without a password.
- Hidden network name
- Adds the hidden-network flag to the code. Leave it off when the network name appears in a phone's Wi-Fi list.
- Error correction
- This page opens at Q, which can recover more damaged code than Medium but holds less data. Scan-test the final size.

What the image stores
The code stores a short text record with the security type, network name, password when needed, and an optional hidden-network flag. It does not contact the router or verify that the credentials work. The image is made on your device, and a phone decides what to do when it scans the record. Test the downloaded image before putting it on a guest sign, and replace the sign if you change the password.
Questions about Wi-Fi QR Code
Can someone read the password from the QR image?
Yes. The password is stored in the code for a protected network. Share the image only with people who may use that network.
Which security setting should I choose?
Match the network itself. WPA covers common WPA and WPA2 personal networks; WEP is for older WEP networks. Choose Open network only when no password is required.
Will a hidden network work?
The code can include a hidden-network flag. Scanning support varies by phone, so scan-test it with the actual network before printing it.
Can I use a semicolon in the password?
Yes. The tool escapes punctuation that separates Wi-Fi fields, so a semicolon stays part of the password instead of ending it.
