QR Code Wi-Fi Generator
Create a QR code for your Wi-Fi network in seconds. Guests scan it with the phone camera and join without typing the password. Download it as a PNG or SVG file.
The QR code is created inside your browser. Your Wi-Fi name and password are never sent to a server or saved. Guests can scan it with the phone camera to join the network.
What Is a Wi-Fi QR Code?
A Wi-Fi QR code is a square barcode that holds your network name, password and security type. When a guest points a phone camera at it, the phone offers to join the network automatically. Nobody has to read out a long password, type it wrongly or ask again later.
Our free QR code Wi-Fi generator creates this code in your browser in a few seconds. You enter the network details, check the preview and download the code as a PNG image or as a sharp SVG file that is ready to print.
How to Create a Wi-Fi QR Code
- Type your Wi-Fi network name exactly as it appears on your devices. Capital letters and spaces matter.
- Enter the Wi-Fi password and choose the security type. Most home and office routers use WPA / WPA2 / WPA3.
- Tick Hidden network only if your router does not broadcast its name.
- Choose colours and a download size if you want, then check the live preview.
- Press Download PNG or Download SVG. Test the code with your own phone before you print it.
How Guests Connect With the QR Code
On an iPhone or iPad with iOS 11 or newer, open the Camera app and point it at the code, then tap the Wi-Fi banner that appears. On most Android phones with Android 10 or newer, open the Camera app or Google Lens, scan the code and tap Connect. Some Android phones also have a QR scanner in the Wi-Fi settings. The phone joins the network without the guest typing a password.
Security Types Explained
- WPA / WPA2 / WPA3: the standard choice for almost every modern router. Passwords must be 8 to 63 characters long.
- WEP: an old and weak standard. Only choose it if your old router really uses it, and consider upgrading the router.
- None (open network): a network with no password. The QR code then only contains the network name.
- Hidden network: select this when the router does not broadcast its name, so the phone knows it must look for it by name.
Where to Use a Wi-Fi QR Code
A Wi-Fi QR code is useful in cafes and restaurants, hotel rooms, holiday rentals, offices and meeting rooms, shops, clinics, schools, event venues and at home for visitors. Print it and place it on a table card, a wall frame, the fridge or the reception desk. You can also add it to a welcome guide or a presentation slide at an event.
Tips for a QR Code That Scans Every Time
- Use a dark code on a light background. Keep the contrast high and avoid inverted colours.
- Print it at least 2 cm (about 0.8 inch) wide, and larger if people will scan it from a distance.
- Leave the white border around the code. It is part of the code and helps cameras find it.
- Use the SVG file for posters and professional printing, because it stays sharp at any size.
- Keep error correction on Medium for normal printing. Higher levels make the code denser.
- Always scan the printed code with an iPhone and an Android phone before you use it.
Privacy and Safety
Your network name and password are never sent anywhere. The QR code is built inside your browser and nothing is saved by the tool. Keep in mind that a Wi-Fi QR code contains the password in a form that any QR scanner can read, so only share it with people you trust. If you display it in a public place, use a separate guest network, and if the code gets shared too widely, change your Wi-Fi password and create a new code.
Frequently Asked Questions
Is the QR code Wi-Fi generator free?
Yes. The tool is free, requires no sign-up and does not add a watermark or limit the number of codes you create.
Is my Wi-Fi password sent to a server?
No. The QR code is created inside your browser. Your network name and password are not uploaded or saved by the tool.
Which phones can scan the Wi-Fi QR code?
iPhones with iOS 11 or newer and most Android phones with Android 10 or newer can scan it with the normal camera app. Older Android phones may need a QR scanner app or Google Lens.
Which security type should I choose?
Choose WPA / WPA2 / WPA3 for almost all modern routers. Choose WEP only for very old routers and None only if your network has no password.
Does the QR code stop working if I change my Wi-Fi password?
Yes. The code contains the password that you entered, so you need to create and print a new code after you change the password or the network name.
Can I print the QR code?
Yes. Download the PNG for everyday printing or the SVG for large prints and posters. Print it at least 2 cm wide with dark ink on a light background.
Why can some phones not connect after scanning?
The most common reasons are a mistake in the network name or password, a wrong security type, or a hidden network that was not marked as hidden. Check these details and create the code again.
