Why use this tool
Guests don't ask for the password or fumble with special characters. Scan → 2 seconds → online.
Cafes, restaurants, offices look cleaner with a printed QR than with a password scribbled on A4.
When you rotate the password, just regenerate the QR and replace the sticker — no announcement needed.
How to use
- 1Enter the SSID (WiFi name) — case-sensitive, spaces allowed.
- 2Pick encryption: WPA (most common, modern routers), WEP (old routers), or nopass (open WiFi).
- 3Enter the password (≥8 chars for WPA). Special characters like ; \ : " are auto-escaped.
- 4Tick "Hidden network" if the WiFi doesn't broadcast its SSID.
- 5Download, print, laminate. Test with an iPhone and an Android before mounting.
How does a WiFi QR work?
WiFi QR follows the Wi-Fi Easy Connect format supported by iOS 11+ and Android 10+. The QR encodes: WIFI:T:WPA;S:NetworkName;P:password;H:false;; — T is encryption, S is SSID, P is password, H is hidden.
When a phone camera scans a WiFi QR, the OS recognizes the format and shows "Join 'NetworkName'?". One tap → the phone fills in the password and connects. The password never appears on screen.
Perfect for cafes, AirBnBs, coworking spaces — strangers don't have to ask for or type complex passwords. iOS 11+ supports WiFi QR through the default Camera app, no third-party app needed.

Use cases
Sticker on the table or in the menu. Customers check in and they're online.
WiFi QR in the welcome booklet — guests don't message the host.
QR at reception for visitors and meeting guests.
Event banner with a WiFi QR so 100+ attendees can connect quickly.
Guest-network QR for visitors, without sharing the internal password.
WiFi QR for students — no reading out a 16-char password.
WiFi QR standard format
The Wi-Fi Easy Connect format: WIFI:T:<auth>;S:<ssid>;P:<password>;H:<hidden>;; — T is WPA/WEP/nopass, S is SSID, P is password, H is true/false.
Special characters in SSID/password (semicolon ; backslash \ colon : quote ") must be escaped with \. This tool escapes them automatically — just paste the password as-is.
Compatibility: iOS 11+ (camera app), Android 10+ (camera + Google Lens), Samsung Galaxy S8+, Huawei EMUI 9+. On older devices, the user still sees the text WIFI:T:WPA;... — they must copy-paste manually.
WiFi QR FAQ
What about Unicode or emoji passwords?
They work — WiFi QR supports full UTF-8, including diacritics and emojis. Some old routers reject special-character passwords though — test with your router first.
Can I hide the password — only print the QR, not the text?
That's the main upside: the password is inside the QR, not on the printed text. Scanners only see a "Join WiFi?" prompt — no password reveal.
Can someone hack the password from the QR?
If someone photographs the QR and decodes it, they'll see the password in plain text — QR is encoding, not encryption. Place the QR only where shop guests see it, not on public Facebook/website.
Can one QR cover both 5GHz and 2.4GHz?
Yes, if both networks share the same SSID + password (only band differs). One QR is enough — the phone picks the better band on its own.
Will it work on iOS 10 or earlier?
Old iOS scans the QR but doesn't auto-join — it just shows the WIFI:T:WPA;... text. Users must go to Settings → WiFi manually. Upgrade to iOS 11+ for the best UX.
