Make a QR code for a link, Wi-Fi network, contact card or message. It's built in your browser, so there's no sign-up, no watermark, and no scan tracking — and the code keeps working long after we're gone.

Scanning this joins the network — handy for a guest Wi-Fi card on the fridge.
PNG only. Keep good contrast or scanners will struggle.
Most "free" generators hand you a code pointing at their short link, so they can count scans — and your poster dies the day they do. This encodes your data directly into the code. No middleman, no expiry.
A QR code is pure arithmetic, so it's all done here on your device. Your Wi-Fi password or phone number never reaches a server — turn off your network and it still works.
No sign-up, no trial, no logo stamped in the corner, and no limit on how many you make. Print them commercially if you like.
