About this tool
When to use it
Create a QR payload containing network settings or decode a saved QR image to inspect its WiFi fields.
How to use it
Enter the exact SSID, security type, password, and hidden-network setting, then generate. Inspect the text payload before distributing the image. Decode a saved image to confirm fields without attempting a network connection.

Worked examples
An open test network
Input
SSID: Demo; Security: Open network; Hidden: offExpected output
WIFI:T:nopass;S:Demo;P:;H:false;;An open network has an empty password field. Reserved delimiters in values are escaped when necessary.
Errors and unsupported input
An SSID exceeds 32 UTF-8 bytesUse the exact valid network name. Multi-byte characters consume more than one byte, so a 32-character name may exceed the byte limit.

Questions
Frequently asked questions
Does a generated image prove the WiFi password works?
No. It contains the values you entered. Test with an authorized device and the real network before distributing it.
What happens if I upload a normal non-WiFi QR code?
The decoder shows its text and explains that no recognized WiFi payload was found. It does not invent network settings from ordinary text.
