Frequently asked questions
Why do QR codes from some websites stop working after 14 days?
Some providers encode a redirect URL pointing to their own servers and require a subscription after a trial. NextGenToolkit encodes your data directly into the static QR matrix so it never expires.
Which error correction level should I choose for print or logo overlays?
Choose Level H (High, 30% recovery), which allows up to 30% of the QR code to be covered or smudged while remaining scannable.
How does the Wi-Fi QR Code mode work?
It formats your network SSID, encryption type (WPA/WPA2), and password into the standard `WIFI:T:WPA;S:...;P:...;;` schema recognized natively by iOS and Android cameras.
Why download SVG instead of PNG for printing?
Vector SVG paths scale infinitely in Adobe Illustrator, Figma, or print flyers without pixelation.
Are my Wi-Fi passwords sent to a server when generating a QR code?
Never. The QR matrix is computed locally in your browser.
