Your WiFi QR Code
Fill in your network name and password, then click Generate.
Before you print this code: scan it with a phone camera and confirm it joins the correct network. Wrong SSID capitalization or an extra space in the password is the most common reason a WiFi QR code fails.
Keep it private: anyone who scans this code can join your network — the password is embedded directly in the pattern. Don't post it somewhere public unless you want guests to have access.

Repeating a long, case-sensitive WiFi password to every guest gets old fast. A WiFi QR Code Generator packages the network name, security type and password into a scannable code. On a compatible phone, scanning the code prompts the user to join the network without entering each detail manually.

The network name is also called the SSID. It must be entered exactly as it appears in the router settings, including capital letters, spaces and punctuation. Choose the matching security option, add the current password, mark the network as hidden when necessary and generate the code. The tool handles the required WiFi QR formatting for you.

SanishTech supports the common choices shown in the live form: WPA/WPA2/WPA3, WEP and an open network with no password. The generated image is static. If the SSID, security type or password changes, the old code cannot update itself and must be replaced.

Privacy and safety note: Your SSID and password are processed locally in your browser and are not uploaded to generate the image. However, the credentials remain encoded inside the finished QR pattern. Anyone who can scan or decode that image may be able to recover them, so use a separate guest network for public signs and keep home-network codes where only trusted visitors can see them.

WiFi QR Code Generator Features

  • Complete network fields: Enter the SSID, security type and password needed to build a usable WiFi QR code.
  • WPA, WEP and open-network options: Choose WPA/WPA2/WPA3 for most current password-protected networks, WEP only for a matching legacy setup, or No Password for a genuinely open network. The current form is not intended for enterprise networks that require a username, identity or certificate.
  • Hidden network support: Mark an SSID that is not broadcast so the appropriate hidden-network value is included in the code.
  • Automatic special-character handling: The generator escapes reserved characters in the SSID and password when building the WiFi data string.
  • Custom scan settings: Choose the available size, error correction, foreground colour, background colour and safe margin.
  • Browser-side output: Generate the code on your device, then download the PNG or copy the image without creating an account.

The commonly used WiFi QR format labels the authentication type, SSID, password and hidden-network status. The ZXing format documentation also explains why reserved characters such as backslashes, semicolons, commas, quotation marks and colons must be escaped. You do not need to build or escape that string manually here.

How to Use the WiFi QR Code Generator in Three Steps

  1. Enter the network details: Type the SSID exactly, select the security type, enter the current password and mark the hidden-network option only when the router does not broadcast its name.
  2. Customize and generate: Choose the available image size, error correction, colours and safe margin, then select Generate WiFi QR Code.
  3. Scan-test and download: Use a phone that is not already connected to confirm the prompt joins the correct network. Download the PNG or copy the image only after the test succeeds.

Testing with a disconnected phone matters. A device that is already using the network can make a broken code look successful because it may stay connected even when the encoded password is wrong.

Benefits of This WiFi QR Code Generator

  • Less password typing: Guests do not need to copy a long mixture of letters, numbers and symbols on a small keyboard.
  • Fewer connection mistakes: The exact SSID, security type and password are encoded once instead of being repeated differently to every visitor.
  • Faster guest onboarding: A printed card can help visitors connect at a home, office, café, hotel, Airbnb, clinic or event venue without waiting for staff.
  • Private generation: The WiFi QR Code Generator creates the image in the browser, so the entered credentials are not sent to SanishTech for rendering.
  • Reusable sharing: One tested sign can serve many guests until the network details are changed or access needs to be revoked.

Example: Using the WiFi QR Code Generator for a Rental

Imagine a holiday-rental host who keeps receiving the same message: “What is the WiFi password?” The router has a separate guest network named LakeView-Guest, protected with WPA2 and a strong password created for visitors.

The host enters LakeView-Guest exactly, selects the WPA/WPA2/WPA3 option, adds the guest password and leaves Hidden Network unchecked because the SSID is visible. A dark foreground, light background and safe margin are used for the printed card. After generating the code, the host turns off mobile data, disconnects from WiFi and tests the code on two phones.

The finished sign says “Scan to join guest WiFi” and sits inside the property rather than in a street-facing window. The host keeps the main household network private. When the guest password is rotated later, a new code is generated and every old printed card is removed. The QR Code Size Calculator can help estimate a starting print size, while the Online QR Code Scanner can decode a saved image for checking.

Five Tips for a Safer, Reliable WiFi QR Code

  • Copy the SSID exactly: Network names and passwords can be case-sensitive. Watch for capital letters, leading or trailing spaces and similar-looking characters. Choose the security type shown in the router settings, not the one that merely sounds newest.
  • Scan-test special characters: The tool escapes reserved characters automatically, but a real device test is still essential when the SSID or password contains punctuation. Test on more than one phone when the sign will serve many visitors.
  • Share a guest network: A WiFi QR code does not conceal the password. A standard decoder can reveal the stored data. For a café, office, rental or public waiting area, isolate visitors on a guest network instead of exposing the network used by staff, computers or smart-home devices.
  • Replace the code after a password change: The image is static and does not expire on a timer. It becomes outdated when the SSID, password or security configuration changes. Remove old copies promptly when access is revoked.
  • Protect the printed pattern: Keep strong contrast and preserve a clear margin around all sides. DENSO WAVE's QR Code guidance calls for a four-module quiet zone. Test the final printed size and placement, not only the preview on a bright screen.

Frequently Asked Questions

Is this WiFi QR Code Generator free?

Yes. You can generate, copy and download a WiFi QR code as a PNG without creating an account or starting a paid plan.

How do I make a QR code for my WiFi password?

Enter the network name exactly, choose its security type, add the current password, mark the hidden option when needed and select Generate WiFi QR Code. Test the result with a disconnected phone before sharing it.

Is my WiFi password uploaded to SanishTech?

No. The network name and password are processed locally in your browser to create the QR image. They are not uploaded to SanishTech for generation.

Can someone see the password stored in a WiFi QR code?

Yes. The password is encoded in the QR pattern and can be recovered with a compatible decoder. Treat the image like a visible password card and share a guest network when the code will be displayed publicly.

Will a WiFi QR code work on iPhone and Android?

Many modern iPhone and Android devices understand the common WiFi QR format and show a prompt to join. Support can vary by operating-system version and camera app, so test the code on the devices your guests are likely to use.

What security type should I choose?

Select WPA/WPA2/WPA3 when the router uses one of those common password-protected modes. Choose WEP only for a matching legacy network, and choose No Password only for a genuinely open network.

Can I create a code for a hidden WiFi network?

Yes. Enter the hidden SSID exactly and enable This is a hidden network before generating. The code includes the hidden-network indicator alongside the other credentials.

What happens when I change the WiFi password?

The old code still contains the previous password and will no longer connect new guests correctly. Generate a fresh code with the updated credentials and replace every displayed or shared copy.

Can the password contain spaces or special characters?

Yes. The generator escapes reserved WiFi-format characters automatically. Enter the password exactly and always scan-test it, especially when it contains backslashes, semicolons, commas, quotation marks or colons.

Does a WiFi QR code expire?

The static code does not have a built-in expiry date. It remains usable while the encoded SSID, password and security settings stay valid and the network remains available.
