    This free Wi-Fi QR code generator turns your network name and password into a code that guests scan with their phone camera to join, with no spelling out of long passwords. It handles WPA2, WPA3, WEP and open networks, including hidden ones, and it runs entirely in your browser.

    This Wi-Fi QR code generator is built for anyone who shares Wi-Fi regularly: home users with visiting friends, rental hosts, small cafés and offices, and homelab owners who want a clean guest network card on the fridge.

    What This Wi-Fi QR Code Generator Does

    You type in three things (network name, security type and password), and the Wi-Fi QR code generator builds the standard WIFI: text that iPhone and Android cameras recognise. It then renders that text as a QR code you can export or print.

    • All common security modes: WPA/WPA2/WPA3 Personal, WPA3-only (SAE), legacy WEP, and open networks without a password
    • Hidden network support: adds the flag phones need to find a network that does not broadcast its name
    • Correct escaping: semicolons, commas, colons, quotes and backslashes in your SSID or password are escaped automatically, so tricky passwords still work
    • Unicode names: SSIDs with accents, Cyrillic or emoji are encoded as UTF-8, and the tool counts bytes against the 32-byte SSID limit
    • Input checks: warns about WPA2 passphrases outside 8–63 characters, WEP keys of the wrong length, and stray spaces at the start or end
    • PNG and SVG export: PNG at 512, 1024 or 2048 px, and a crisp SVG for design tools and large prints
    • Printable Wi-Fi card: a clean card with your title, the QR code, the network name, the password and an optional note, at 1, 2, 4 or 6 cards per page

    The Wi-Fi QR code generator updates the preview as you type. The export and print buttons only become active once the code is valid.

    How to Use the Wi-Fi QR Code Generator

    1. Enter your network name (SSID) exactly as your router shows it, including capital letters and spaces.
    2. Pick the security type. If you are unsure, keep WPA / WPA2 / WPA3 Personal. It fits most home routers.
    3. Type the Wi-Fi password. Use the Show button to double-check it, because a single typo makes the code useless.
    4. Tick Hidden network only if your router is set to hide its SSID.
    5. Scan the preview with your own phone to test it, then download a PNG or SVG, or press Print card.

    WPA3, Hidden Networks, and Printing Explained 🔐

    Which security option should you pick?

    Every Wi-Fi QR code carries a short text payload. For a typical home network it looks like this:

    WIFI:T:WPA;S:MyHomeNetwork;P:correct-horse-battery;;

    T:WPA is not limited to old WPA. According to the Wi-Fi Alliance WPA3 specification, it means “password-based authentication” and covers WPA2, WPA3, and mixed transition-mode networks. That is why the default option in this Wi-Fi QR code generator works for most routers.

    If your router runs in WPA3-only mode, choose WPA3 Personal only (SAE). The Wi-Fi QR code generator then adds R:1, the Transition Disable flag from the same specification, which tells supporting phones not to fall back to WPA2:

    WIFI:T:WPA;R:1;S:MyHomeNetwork;P:correct-horse-battery;;

    Some Android builds and Linux desktops write T:SAE instead. It is not in the specification, but Android devices understand it, so the tool offers it as an Android-style encoding option for the rare scanner that rejects the default.

    Choose None — open network for guest networks without a password, and WEP only for very old hardware. WEP can be cracked in minutes, and the tool reminds you of that.

    Hidden networks

    A hidden network does not announce its name, so a phone has to search for it on purpose. Ticking Hidden network in the Wi-Fi QR code generator adds H:true to the payload, which tells the phone to do exactly that.

    Tips for a card that scans on the first try

    • Keep the quiet zone at 4 modules. This white border is part of the QR code standard, and scanners rely on it.
    • Use error correction M for screens and Q or H for printed cards that might get creased or smudged. Higher levels make the code denser but more resilient.
    • Leave Print the password on the card switched on so people whose devices can’t scan QR codes can type it in.
    • Print on white or light paper. The generated codes are black on white on purpose, which gives every scanner the best contrast.

    Practical Use Cases

    These are the situations where a Wi-Fi QR code generator saves the most time and the most spelled-out passwords:

    • 🏠 Visitors at home: stick a card on the fridge or near the router so friends never have to ask for the password again.
    • 🛏️ Short-term rentals: put a framed card in the apartment with a friendly note, and save yourself the “what’s the Wi-Fi?” messages.
    • ☕ Cafés and small offices: print 6 table cards on one page for a customer network. Rotate the password and reprint in a minute.
    • 🧪 Homelab and IoT networks: when you set up a separate guest or IoT SSID, for example while following my OpenWrt Wi-Fi 6 and Wi-Fi 7 setup guide, print a card for it straight away.
    • 🔑 Strong passwords without the pain: generate a long random passphrase with the Secure Password and Passphrase Generator, store it in a self-hosted Vaultwarden password manager, and let the QR code do the typing.

    If you need to share contact details instead of network access, the companion vCard QR Code Generator turns a business card into a QR code the same way.

    Privacy, Ads, and Data Policy

    A Wi-Fi password is exactly the kind of thing you should not paste into a random website. This Wi-Fi QR code generator is built with that in mind:

    • ✅ 100% free: no registration, no account, no usage limits
    • ✅ No data storage: your SSID and password never leave the browser, and they are not saved in cookies, local storage or the page URL
    • ✅ No ads in results: no watermarks, logos or tracking links inside your QR code or printed card
    • ✅ Client-side only: the only network request is loading the open-source QR library itself; generation, export and printing all happen on your device

    You can load the Wi-Fi QR code generator, switch your device to airplane mode, and it keeps working.

    Open Source and Self-Hosting

    The Wi-Fi QR code generator is open source and lives in the vahac-tools repository on GitHub, next to every other tool on this site. It is a single folder with three files (HTML, CSS and JavaScript), so you can host it on any static web server, run it from your homelab, or open it straight from disk.

    The only dependency is the MIT-licensed qrcode-generator library, the same one used by the vCard tool. Forks and pull requests are welcome, whether that is a new card layout or a translation.
