Wi-Fi QR code generator

Ready

Turn a Wi-Fi network name and password into a QR code. Pick the security type (WPA, WEP, open). Everything runs in this browser, the password never reaches a server.

All tools are free to use. File size and processing limits may vary by tool.

How to use

Type the network name, password and security type, then run; print the code and stick it on the guest card. Handing out a separate guest network is safer.

How are files processed?

Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
