WiFi QR code questions
Short answers about compatibility, privacy, downloads, and common connection problems.
How does a WiFi QR code work?+
It stores your network name, security type, password, and hidden-network setting in a standard WiFi text format. A compatible phone reads that data and offers to join the network. The person scanning still confirms the connection on their device.
Is my WiFi password uploaded?+
No. Generation and validation run locally in your browser. The page does not need an account or an API request containing your WiFi details. The downloaded QR code does contain the credentials, so share or display it only where intended users can access it.
Does it support WPA3?+
Yes. WPA, WPA2, and WPA3 Personal networks use the WPA value recognized by current phone QR readers. Enterprise networks that require usernames, certificates, domains, or EAP settings are not supported by this generator.
Why will a phone not connect after scanning?+
Check capitalization and spaces in the network name and password, confirm the security type, and enable Hidden network if the SSID is not broadcast. Test the on-screen code on another current phone. If only the printed version fails, increase its size, contrast, and white margin.
Can the WiFi name or password contain special characters?+
Yes. The generator escapes reserved punctuation before it builds the WiFi payload. Enter the real characters exactly as configured on the router; do not add your own backslashes. Always test the result because device support can differ.
What happens after I change the WiFi password?+
The old QR code still contains the old password, so it must be replaced. Return to the generator, enter the new credentials, test the new result, and remove old digital or printed copies that guests might continue to scan.
Can I print the QR code for guests?+
Yes. You can download the code alone as PNG or SVG. For a complete layout that also shows the network name and password, open the printable WiFi sign tool and choose a suitable scene and paper size.
Is the generator really free?+
Yes. The core generator, browser-based validation, PNG and SVG downloads, and printable sign options are available without registration, a watermark, or an expiration date.
