Wi-Fi QR code generator

Your network credentials stay local

The SSID, password, security type, and hidden-network flag are assembled into the common Wi-Fi QR payload format inside the browser. Special characters are escaped before encoding. A locally bundled QR library creates the matrix, and browser canvas creates the PNG. Gypes does not intentionally upload or store the credentials.

Choose the actual security type

WPA/WPA2 Personal is the normal choice for password-protected home and guest networks. WEP is retained only for legacy equipment and is not considered secure. Open networks have no password; if that option is selected, the password field must be empty so an accidental credential is not silently discarded.

Password rules prevent common unusable codes

WPA/WPA2 input accepts a printable ASCII passphrase of 8–63 characters or a 64-digit hexadecimal key. WEP accepts common 5- or 13-character printable ASCII keys and 10- or 26-digit hexadecimal keys. Router and client implementations can impose additional restrictions, especially for older devices.

Test before displaying or distributing

Operating-system support for Wi-Fi QR payloads varies. Scan the downloaded image with the devices guests will actually use, confirm the displayed network name, and verify connection. Keep the four-module white border, preserve the black-on-white colors, and print at a size appropriate for viewing distance.

Anyone who can scan this code may obtain the network credentials. Share it only where intended, rotate exposed passwords when necessary, isolate guest devices where practical, and never use WEP for a network that can support modern security.
