Wi-Fi QR code generator for easy guest access

Help guests connect without typing your Wi-Fi password. Enter your network details, generate a code, and download it for a welcome card, reception desk, or a quick scan from your screen.

A shortcut to your Wi-Fi network

A Wi-Fi QR code stores connection details in a format compatible scanners can recognize. Your phone reads the network name, security type, and password, then may offer to join. The generator does not change your router settings or check whether a connection succeeds.

These codes do not configure a static IP address, DNS server, or radio band. Set those on the device or router when needed. This tool accepts network names as text, rather than arbitrary binary SSIDs.

Use your existing network name and password exactly, including uppercase letters and spaces. A guest network is useful when you want to share access separately from your main network. Always scan the finished code with the phones your guests use before printing copies.

Choose the matching connection type

Select Hidden network only if your router does not broadcast the network name. Hiding a name is not a security upgrade and does not keep the QR password secret.

Scanner support varies, particularly for WPA3, Enhanced Open, Easy Connect, and unusual characters. A valid QR image is not a guarantee that every phone can configure the connection. The Android Wi-Fi URI parser  documents several of these reader conventions.

Wi-Fi security: from least secure to strongest

Match the generator to your existing router settings. Selecting a stronger type here does not upgrade the network. The colored shields below are a practical guide to wireless protection, not a security test of your router: red means unsafe, amber means limited protection, blue means good protection, and green marks the strongest personal option listed.

The WPA / WPA2 Personal selector covers two different security generations because they share a QR format. Check the router: WPA2 with AES is different from original WPA or a WPA/WPA2 router compatibility mode. Apple’s router security guidance  explains these settings, and Microsoft recommends WPA3 where supported .

OWE sits outside a simple password-security ladder: it improves privacy on public networks, but does not prove that a hotspot is trustworthy. On transition networks, older devices may connect without encryption. This generator’s no-password QR payload cannot require OWE. See the OWE specification’s security considerations .

Security varies by setup Wi-Fi Easy Connect (DPP) uses an authenticated, encrypted setup exchange on compatible devices. It is not a stronger rung above WPA3: ongoing protection depends on the network configuration it provisions. Here, you supply an existing device-issued URI; the generator renders it and checks its basic structure, without validating its cryptography or configuring devices. Android’s Easy Connect documentation  describes that provisioning process.

Whatever mode you use, treat a password-bearing QR image like the password itself. Stronger Wi-Fi encryption does not encrypt the contents of the QR image.

Clear exports for screens and print

Download PNG for a ready-to-use image. The free download includes a white border around the black squares. Keep that border intact and leave good contrast around the code; DENSO WAVE’s sizing guidance  explains the four-module quiet zone.

In Options, choose an image size up to 2,048 pixels and an error correction level. The actual pixel size is rounded down to keep every square a whole number of pixels wide. Medium correction is the default; higher levels tolerate more damage but can produce a denser code. See DENSO WAVE’s error correction explanation .

For a compatible WPA3 setup, Disable WPA2 fallback adds the R:1 request. Use it only when your network supports that choice; scanners may ignore it. It does not reconfigure the router.

What the code contains

A simple example, using fictional credentials, is:

WIFI:T:WPA;S:Home Guest;P:example-password;;

The generator escapes separators such as semicolons and backslashes for you. Show QR data reveals the encoded text; Copy QR data copies it, including the password. The code itself also reveals those details to anyone who can decode it. Masking the password field does not protect a shared QR image.

Network names can contain 1–32 UTF-8 bytes. WPA/WPA2 accepts an 8–63-byte passphrase or 64 hexadecimal digits. WEP accepts 5, 13, 16, or 29 ASCII characters, or 10, 26, 32, or 58 hexadecimal digits. WPA3 passwords have a tool limit of 1,024 UTF-8 bytes; your router or phone may impose a smaller limit. Control characters and malformed Unicode are rejected; values are never silently trimmed or truncated.

Easy Connect URIs are preserved verbatim, with basic structure and public-key-field checks only. Their cryptographic validity and device compatibility are not verified. The shared encoder accepts up to 2,400 UTF-8 bytes; actual QR capacity also depends on the selected correction level. If a value does not fit, the tool reports it instead of generating an incomplete code.

Does my Wi-Fi QR code expire?

There is no built-in expiry or scan limit. It continues to contain the details used when you generated it. If the network name, password, or security settings change, generate and share a new code. Downloaded images remain on your device until you remove them.

The tool keeps no saved networks or history. Changing a setting clears the previous code so you cannot accidentally download outdated details. Clear removes the form values and current result; reloading the page starts over.
