Point a phone at the frame on the wall and it joins the network — no password spelled out over coffee. And since it’s drawn in your browser, your WiFi password never leaves this page.
It encodes the network name, security type and password in a format both iOS and Android understand natively — point the camera app at it and the phone offers to join. iOS 11+ and effectively all Android versions support it out of the box.
It is exactly as safe as telling guests the password — the code is the password, readable by anyone who can photograph it. For a guest network that’s the point. Don’t put your admin network on a poster.
The code encodes what you typed, so a new password means printing a new code — thirty seconds here, no account needed, this page will still exist.
Never. The code you download contains your data itself — there is no shortlink, no redirect through our server, no account it belongs to. Services that “expire” QR codes are selling dynamic redirects; a static code like this one works as long as ink and paper do.
No. The code is computed and drawn entirely in your browser — content, colors and logo included. Nothing you type here reaches our server, which is also why the tool is fast.
Yes, within reason — QR readers binarize the image, so shapes matter less than contrast. The rules of thumb: dark code on light background (not the reverse), contrast ratio 4:1 or better, quiet zone ≥ 4 modules, and if you add a logo keep it near 20% with error correction H. The generator warns you live when a choice threatens scannability — and always test the printed code with a phone camera before ordering 5,000 stickers.
