QR Code Generator FAQ
Which error correction level should I pick?
M at 15% suits most prints; choose H at 30% for stickers or logos likely to be scuffed, remembering higher levels make the QR denser for the same content.
Can I encode WiFi login details?
Yes โ the content field accepts the standard WiFi format like WIFI:T:WPA;S:MyNetwork;P:password;; and phones scanning it will offer to join the network.
Why did the QR stop updating?
Very long content can exceed QR capacity at the chosen size; shorten the text or increase the size slider so more modules fit.
