WiFi QR Code Generator

How to use

1. 1Type your network name (SSID) exactly as the router broadcasts it. It is case-sensitive and limited to 32 bytes.
2. 2Pick the security type: WPA2, WPA3, WPA / WPA2 mixed, legacy WEP, or Open if there is no password.
3. 3Enter the password. Use the Show button to double-check it. Special characters are escaped automatically for the payload.
4. 4Tick Hidden network if your SSID is not broadcast. Otherwise leave it unticked.
5. 5Tune the appearance if needed: pick Q or H error correction for printed posters that may get scratched, then adjust module size, quiet zone, and colors.
6. 6Download the QR as PNG or SVG, or copy the SVG markup or raw payload. Test the result with one phone before printing copies.

About this tool

WiFi QR Code Generator turns a network name (SSID), security type, and password into a scannable QR code that iOS Camera (iOS 11 and later), Android Camera (Android 10 and later), and most barcode scanner apps recognize for one-tap join. The tool builds the standardized WIFI:T:<security>;S:<ssid>;P:<password>;H:<hidden>;; payload that the Zxing-derived format defines, automatically backslash-escaping the four characters the spec requires (backslash, semicolon, comma, and double quote) plus the colon inside passwords. The security selector covers WPA2, WPA3, WPA / WPA2 mixed, legacy WEP, and open networks with no password; per the spec, all WPA variants map to the same T:WPA token in the payload. A live validator checks that the SSID fits the IEEE 802.11 32-byte limit, that WPA personal passwords are between 8 and 63 ASCII characters (or a 64-character hex PSK), and that WEP keys are 5 or 13 ASCII characters or 10 or 26 hex characters; it also flags common copy-paste mistakes such as leading or trailing whitespace in the SSID and accidental quote wrapping. A hidden-network checkbox emits H:true; only when ticked, so older scanners that mishandle H:false; will not see it. The QR code itself uses an in-house, ISO/IEC 18004 compliant encoder shared with the general QR Code Generator (versions 1 to 40, error correction L through H). You can pick the foreground and background colors, the module size, and the quiet-zone margin, then download the result as a PNG or as a clean single-path SVG ready for print at any size. The encoded payload is shown alongside the QR with a copy button so you can audit exactly what scanners receive. Everything runs locally; SSIDs, passwords, and the generated code are never sent to a server.
