Make a QR code for your WiFi.
Turn your WiFi network — or any link — into a QR code, add a caption printed above it, and download a PNG or SVG. Your network password is turned into the code right here: it runs entirely in your browser, nothing is uploaded.
High error correction packs more redundancy, so the code survives a logo or a crease. Keep strong contrast — pale codes on pale backgrounds may not scan.
How does a WiFi QR code work?
A WiFi QR code isn't magic — it's a tiny piece of text in a standard format, WIFI:T:WPA;S:MyNet;P:secret;;, that phone cameras know how to read. When someone scans it, the phone offers to join that network for them — no typing the password. WPA / WPA2 / WPA3 all use the WPA setting; pick WEP only for old routers, or No password for an open network.
The caption is drawn onto the image above the code, so a printed card can say what it's for — “Guest WiFi”, “Scan to connect”, “Menu”. It's part of the picture, not part of the code, so it never affects whether the code scans.
Does my password leave my device?
No. The code is generated here in your browser with no server involved, and this page is locked down with a connect-src 'none' policy — the browser physically blocks every network request, so what you type can't be uploaded even by accident. The same promise the rest of this workshop makes. Want to check? Open your browser's Network tab and watch: nothing goes out.
