QR Code Generator: Text, URLs and Wi-Fi

Calculation breakdown
Method, assumptions and worked example
How it works
The text or Wi-Fi payload is encoded locally using a bundled QR library. Wi-Fi separators are escaped so punctuation in the SSID or password is preserved. A white border four modules wide surrounds the symbol; square black modules use whole pixels. UTF-8 text is supported.
Worked example
The default text encodes https://mgcalculator.com/. Download it and scan with your phone camera. For Wi-Fi, enter the actual network name and security type; the QR contains those credentials in a readable encoded form.
Using the result
Static QR codes do not need an account or expiry service. A URL can still stop working if its destination changes. Long content increases density; reduce the content or error-correction level if capacity is exceeded. Always test a saved QR before printing it. Anyone who can scan a Wi-Fi QR can retrieve its credentials.
Frequently asked questions
Does the code expire?
The static symbol does not expire, but its linked destination may change or disappear.
Can I use it for WPA3 Enterprise?
No. This tool provides a common personal Wi-Fi payload, not enterprise authentication provisioning.
