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.
How do I find my Wi-Fi name?
iPhone / iPad: Settings → Wi-Fi; the network with the blue checkmark is your name. To copy it: take a screenshot of that screen, open it, then press and hold the name to select it with Live Text and tap Copy. (Or use the shortcut above, which fills it in for you.)
Android: Settings → Network & internet → Wi-Fi (or Internet), then tap the connected network at the top. To copy it: on most phones, press and hold the network name and choose Copy.
Mac: click the Wi-Fi icon in the menu bar (top-right); the checked network is your name. To copy it exactly: open Terminal (⌘Space, type “Terminal”) and run networksetup -getairportnetwork en0, which prints the name.
Windows: click the Wi-Fi / network icon in the taskbar (bottom-right); the network marked Connected is your name. To copy it exactly: open Command Prompt (Start, type “cmd”) and run netsh wlan show interfaces; the SSID line is the name.
iPhone shortcut (optional): tap Get the WiFi QR Helper shortcut, then Add Shortcut. Run it (from the Shortcuts app or the share sheet) and it reads your current network name and opens this tool with it filled in. It only reads the name; nothing leaves your phone. Needs the free Apple Shortcuts app; allow it to access Wi-Fi on the first run.
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 password typing needed. 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. The page makes exactly one outside request: an anonymous page-view ping that records the address /qr/ and nothing else. It reads the path only, so your network name and password are never part of it, and the tool's own code cannot make a network request at all. The same promise the rest of this workshop makes. Want to check? Open your browser's Network tab and watch: one line for the ping, and nothing carrying what you typed.
