WiFi QR Code Generator

Generate a QR code that auto-joins a Wi-Fi network when scanned. Uses the standard WIFI: format recognised by iOS 11+ and Android 10+ camera apps.

About WiFi QR Code Generator

WiFi QR Code Generator creates a QR code in the standard 'WIFI:' mecard format that iOS 11+ and Android 10+ recognise natively from the camera app. When a guest at your office, café, AirBnB or event scans the code, their phone offers to join the network in one tap — no typing the SSID, no fumbling with a paper password slip, no typos. The tool supports WPA, WPA2 and WPA3 (the modern default), legacy WEP, fully-open networks, and hidden SSIDs that are not broadcast. It properly escapes special characters in passwords (semicolons, colons, backslashes, quotes) so passwords with punctuation work. A built-in 'printable card' export composes a high-resolution PNG suitable for printing on cardstock — large QR, network name in big bold type, password in monospaced text — ideal for hanging at reception, in a hotel room, or at an event check-in.

Why use WiFi QR Code Generator

  • End the painful experience of every guest typing a 24-character WPA2 password: one scan and they are connected.
  • Standard WIFI: format means no third-party scanner apps required — iOS Camera and Android Camera both recognise the format natively from version 10/11+.
  • Special characters in passwords (quotes, semicolons, colons, backslashes) are correctly escaped per the WIFI: spec so passwords with punctuation work without manual encoding.
  • Hidden networks are supported via the H:true; flag in the WIFI: string — a feature most online generators skip.
  • One-click 'printable card' export composes a high-resolution PNG with the QR plus large readable SSID and password, ready for posting at reception or in a guest room.
  • Runs entirely in your browser — Wi-Fi password never uploads to any server, important for office/IT teams sharing internal credentials.

How to use WiFi QR Code Generator

  1. Type the network name (SSID) exactly as it appears in your router settings — case-sensitive.
  2. Pick the security type from the dropdown: WPA / WPA2 / WPA3 covers the vast majority of modern home and office networks.
  3. Type the Wi-Fi password into the field. Use the eye-icon button to reveal/hide while typing if you want to verify against your router config.
  4. Tick 'Hidden network' only if your SSID is not broadcast — most networks are broadcast and this stays unchecked.
  5. Choose QR size (200 to 600 px) and error-correction level (Level H is the safest choice for printed signs that might be smudged or photocopied).
  6. Click Generate, then download the QR as a plain PNG, or click 'Printable card' to download a full-page sign with the QR plus the readable SSID and password — perfect for hanging at reception.

When to use WiFi QR Code Generator

  • Posting at reception of an office, café or coworking space so visitors join guest Wi-Fi without asking the front desk for the password.
  • Putting in a hotel or short-term-rental welcome packet so guests connect with one scan instead of mistyping a long password from a printed slip.
  • Hanging at a wedding, conference or event venue so attendees join the event Wi-Fi for live photos, votes or session apps.
  • Sharing your home Wi-Fi with house guests by displaying the QR on your fridge or guest-room wall.
  • Distributing on a printed sticker for IoT installers (smart bulbs, security cameras) so end users connect them to the right network without retyping a password.
  • Including in event-check-in materials so on-site staff can quickly connect their phones to a backstage network.

Examples

Café guest Wi-Fi card

Input: SSID: CafeGuest | Security: WPA | Password: latte2026! | Size: 600 px | Error correction: H | Printable card: yes

Output: An 800 × 1100 px printable PNG with 'Wi-Fi Access' headline, large QR, 'Network: CafeGuest' and 'Password: latte2026!' in monospaced text. Print on A5 cardstock for the counter.

Office hidden internal network

Input: SSID: AcmeInternal | Security: WPA2 | Password: C0rp$ecret#2026 | Hidden: yes | Size: 400 px

Output: WIFI:T:WPA;S:AcmeInternal;P:C0rp\$ecret\#2026;H:true;; 400×400 PNG sized for printing on individual employee onboarding sheets — devices probe for the hidden SSID after scan.

Open conference network

Input: SSID: ConfWiFi | Security: Open | Hidden: no | Size: 400 px | Error correction: M

Output: WIFI:T:nopass;S:ConfWiFi;; encoded as a 400 × 400 PNG. Scanning on any modern phone offers a one-tap join with no password prompt — perfect for trade-show signage.

Tips

  • Print the QR card on cardstock, not regular paper — laminated cardstock survives years on a coffee-shop wall.
  • Test-scan from at least one iPhone and one Android device before printing 50 cards — settings sometimes look fine on screen but fail in print.
  • Use Level H error correction when printing on textured or glossy stock that may slightly smudge — the extra robustness is free.
  • Rotate the QR-card password every few months for an office network — print a fresh batch each cycle and replace the old card.
  • Keep the SSID short (under 16 chars) for the densest, most reliably scannable QR — long SSIDs and long passwords combined can produce codes that fail at small print sizes.

Frequently Asked Questions

Does this work with WPA3 networks?▾
Yes. WPA3 uses the same WIFI: T:WPA; format string as WPA2; iOS and Android both negotiate WPA3 automatically when joining a network from a QR. The generator does not need a separate WPA3 mode.
Can I use this for a totally open / no-password network?▾
Yes — pick 'Open / no password' from the Security dropdown. The password field is disabled and the resulting QR uses T:nopass; so the camera app recognises it as an unprotected network and joins without prompting for a key.
What about hidden networks (SSID not broadcast)?▾
Tick the 'Hidden network' checkbox. The resulting WIFI: string includes the H:true; flag so iOS and Android know to manually probe for the SSID rather than waiting to see it in a scan list.
How are special characters in my password handled?▾
Backslashes, semicolons, colons, commas, and double-quotes in your password are escaped according to the WIFI: spec. A password like Pass;\word works correctly — the tool produces P:Pass\;\\word; in the QR and the camera app decodes it back to your real password.
Does the QR code include my password in plain text?▾
Functionally yes — the password is encoded inside the QR's pixel pattern. Anyone who scans the code can read the password, which is the entire point. Treat the QR like the password itself: do not photograph it and post publicly unless the network is intended for public access.
Will my password be sent to your server?▾
No. The QR is generated entirely in your browser. Nothing about the SSID, password, or printable card ever leaves your device — no fetch requests are made beyond loading the qrcodejs library.
What is the printable card and how does it look?▾
It is a single 800 × 1100 px PNG composed in your browser: a large 'Wi-Fi Access' headline, a centred high-resolution QR code, the network name in bold, and the password in monospaced text below — sized for an A5 or letter-half print at 100+ DPI.
My phone shows the QR scanned but does not offer to join the network. Why?▾
Most often: (1) the camera app is too old (iOS 10 or older, Android 9 or older), (2) the SSID has a typo, (3) the security type does not match your actual network (WPA-PSK vs WEP), or (4) the password contains a character that was mistyped. Re-verify SSID and password against your router configuration.

Glossary

SSID
Service Set Identifier — the human-readable name of a Wi-Fi network. The QR encodes this exactly as broadcast (or as configured for hidden networks).
WPA / WPA2 / WPA3
Wi-Fi Protected Access standards (versions 1, 2 and 3) — the modern security protocols for Wi-Fi authentication and encryption. The QR uses T:WPA; for all three because devices auto-negotiate the highest version supported.
WIFI: mecard format
A short text-based encoding for Wi-Fi network credentials, structured as WIFI:T:type;S:ssid;P:password;H:hidden;;. Recognised natively by iOS 11+ and Android 10+ camera apps.
Hidden network
A Wi-Fi network where the SSID is not included in beacon broadcasts. Devices must manually probe for the network. The H:true; flag in the WIFI: string instructs the joining device to do this.
WEP
Wired Equivalent Privacy — an obsolete pre-WPA Wi-Fi security standard. Still occasionally encountered on old equipment; the tool supports T:WEP; for legacy compatibility.
Quiet zone
The white margin around the printed QR code required for reliable scanning. The QR specification requires at least 4 modules of quiet zone on every side.
