Free Wi-Fi QR Code Generator: Share Your Network with a Scan
Sharing Wi-Fi should take less time than reading a long password aloud. Our new free Wi-Fi QR code generator turns your network details into a code that guests can scan with a compatible phone. Enter the network name and password, generate the code, and download a PNG to display or print. No account is required.
It is a useful addition to a kitchen noticeboard, a cafe counter, or a holiday rental welcome sheet. Guests can avoid typing unfamiliar characters, and you can stop answering the same password question every time someone arrives.
How to create a Wi-Fi QR code
You will need your network name, also called the SSID, its security type, and its password if it uses one. You can usually find these in your router settings. A router label is useful only if those details have not changed.
- Open the Wi-Fi QR code generator.
- Choose the connection type that matches your network. WPA / WPA2 Personal is selected by default; check your router settings if you are unsure.
- Enter the exact network name and password, including any spaces and capital letters. Select Hidden network if your router does not broadcast the name.
- Select Generate QR code to create the preview.
- Scan it with a phone to check the connection, then select Download PNG to save the image.
For example, you could generate a code for a guest network named Home Guest and place the downloaded image on a welcome card. Use your actual guest network password when generating the code.
The generator cannot check your router or verify that a password is correct. A successful test scan and connection are the best checks before you share it. If you edit the network details, generate a fresh code before downloading again.
A simple way to welcome guests
At home, a Wi-Fi QR code gives visiting friends and family a convenient way to connect. Display it where guests can scan it, or keep the image ready to show on your screen when someone asks.
For a holiday rental, add the PNG to your arrival instructions or a printed welcome sheet. Label it with the network name so guests know which connection they are joining. A cafe or shared workspace can use the same approach on a counter sign or information card.
If your router offers a separate guest network, consider using that network’s details for your code. The generator uses the information you provide; creating a code does not configure a guest network or change your router settings.
Which Wi-Fi connection type is safest?
For a home or guest network, prefer WPA3 Personal when your router and devices support it. WPA2 / WPA3 mixed mode accommodates older devices. If WPA3 is unavailable, use WPA2 Personal with AES and a strong password. Microsoft’s wireless network guide recommends WPA3 for its improved security.
Here is a practical guide from least secure to strongest personal protection. The colored icons have text labels too: red marks unsafe modes, amber limited protection, blue good protection, and green the strongest personal option here. They describe connection types, not a security scan of your network.
| Connection type | Security guide | What to know before sharing |
|---|---|---|
| Open (no password) | No wireless encryption. A web sign-in page does not secure the Wi-Fi link; keep using HTTPS websites. | |
| WEP (legacy) | Broken encryption, even with a password. Upgrade the router’s security mode. | |
| Original WPA / TKIP | Outdated and best avoided. It is not equivalent to WPA2 with AES. | |
| Enhanced Open (OWE) | Encrypts compatible connections without a password, but does not verify the hotspot’s identity or limit access to your guests. | |
| WPA2 Personal with AES | A practical fallback for older devices. Use a strong password and updated software. | |
| WPA2 / WPA3 Personal (mixed) | Supports both generations; older devices still connect using WPA2. | |
| WPA3 Personal (SAE) | Better protection against offline password guessing. Requires compatible devices and still benefits from a strong password. |
The tool’s WPA / WPA2 Personal option shares one QR format, but the router determines which protection you get. Avoid original WPA and TKIP, including router modes that allow them. Apple’s router settings guide explains the distinction.
OWE improves privacy on public Wi-Fi rather than acting as a password barrier. Its encryption does not establish that a hotspot is trustworthy, as the OWE security specification explains. The generator cannot force a phone to use OWE through the QR code.
Wi-Fi Easy Connect (DPP) is a separate way to set up compatible devices through a secure exchange. Its ongoing network protection depends on the configuration it provisions, so it is not ranked above WPA3. This tool turns an existing device-issued URI into a code; it does not validate its cryptography or perform the setup. See Android’s Easy Connect explanation.
Changing the selector does not change your router. Hidden networks are supported too, but hiding the name adds no encryption. Match your existing settings and test with your guests’ devices: scanner support varies. The generator’s Wi-Fi security guide gives more detail.
Your network details stay in your browser
QR code generation happens locally in your web browser. The tool does not upload your network name or password, and it does not save a history of your credentials. You can clear the form when you are finished.
The QR image itself contains the connection details, including the password for a password-protected network. Anyone who can read the code can recover those details, so share it with the same care you would share the password. A downloaded PNG remains on your device until you delete it.
Download a Wi-Fi QR code for printing
The PNG download can be inserted into a document, welcome sheet, or sign. Under Options, you can choose the image size and error correction level; the defaults are a useful starting point.
Keep the white border around the code, preserve its square proportions, and avoid cropping or stretching the image. Print it clearly with enough space for a phone to scan it comfortably. Test the finished print at its intended size and location before making copies.
Common questions
Can an iPhone or Android phone scan it?
Many phones recognize personal Wi-Fi QR codes through their camera or a built-in scanning feature. The exact behavior depends on the phone, software, and connection type. A compatible scanner can offer to join the network; test your code on the devices you expect guests to use.
Does the Wi-Fi QR code expire?
The generated code has no built-in expiry or scan limit. It will continue to contain the same details. If you change the network name, password, or security settings, generate a replacement and update any printed copies.
Can I create a code for Wi-Fi without a password?
Yes. Choose Open (no password) and enter the network name. If the network requires a separate sign-in or acceptance page after connecting, scanning the QR code does not bypass that step.
