How to Use the Free WiFi QR Code Generator

Share your WiFi without saying the password out loud or typing it on every phone. Guests scan the code and join your network in seconds.

  1. You are on the WiFi tab already. If you are not, click the WiFi tab at the top of the tool.
  2. Type your network name in the box called WiFi network name (SSID). This is the name you see when you look for WiFi on your phone. It is case sensitive.
  3. Pick your security type in the box called Security type. Most home routers use WPA / WPA2.
  4. Type your WiFi password in the box called WiFi password. Type it exactly as it is set on your router.
  5. Download the code. The preview updates by itself as you type. When it looks right, click Download PNG, print it, or show it on your phone.

Worked example

Try it with these details:

  • WiFi network name (SSID): HomeWiFi
  • Security type: WPA / WPA2
  • WiFi password: mypassword123

Example WiFi QR code for the network HomeWiFi

Result: Scan the code with your phone and it joins the HomeWiFi network, with no typing needed. The code never expires, so it works until you change the password.

What the code holds: WIFI:S:HomeWiFi;T:WPA;P:mypassword123;;

There is no Generate button on this tool. The preview updates by itself as you type.

How to make a WiFi QR code

Making a WiFi QR code takes less than a minute. Follow these steps and test the code before you share it.

  1. Find your WiFi network name. This is the SSID you see when you look for WiFi on a phone. It is case sensitive, so type it exactly as it appears, including capital letters and spaces.
  2. Pick the security type. Most home networks use WPA or WPA2. If your network has no password, choose No password. If you are not sure, check your router settings or ask the person who set up the network.
  3. Type your WiFi password exactly as it is set on your router. WiFi passwords are case sensitive, so a capital letter in the wrong place will stop guests joining.
  4. Click Download PNG or Download SVG. PNG is best for screens and small prints, and SVG is best for large prints because it stays sharp.
  5. Test the code with your own phone before you print it. Open your camera, scan the code, and check that it joins the network without asking for a password.
  6. Print the code or put it in a frame. A code of about 5 cm works well on a table card. For a wall sign, make it bigger so guests can scan it from a few steps away.

What is a WiFi QR code and how does it work

A WiFi QR code stores your network name, security type and password inside the code itself. When a phone camera reads the code, the phone sees that it is a WiFi code and offers to join the network. The guest does not have to type the password, spell it out or ask you to repeat it. This is useful when the password is long, has random letters and numbers, or when many people need to join at the same time.

The code is read by the phone camera or by a QR scanner app. On an iPhone, the camera app reads it. On most Android phones, the camera app or Google Lens reads it. Some older Android phones need a scanner app. Once the phone reads the code, it shows a button to join the network. One tap joins, and the phone saves the network for next time, just as if the password had been typed in by hand.

Where to use a WiFi QR code

A WiFi QR code is useful anywhere people need to join a network. At home, put one in the living room or guest room so visitors can join without asking. In a cafe, restaurant or shop, put one on the counter or on each table so customers can join while they wait. In an office, put one at reception or in meeting rooms so visitors and new staff can join fast. In a guesthouse, hotel or holiday rental, put one in the room and in the common area so guests can join on arrival without calling the owner.

Schools and libraries use WiFi QR codes in classrooms and reading rooms. Event organisers use them at conferences, weddings and community events, where many people arrive at once and need WiFi. A printed code is much faster than reading out a password to a room full of people, and it avoids mistakes.

WPA, WEP and open networks

Most modern routers use WPA2 or WPA3. Choose WPA in the generator for these networks. Some older routers use WEP, which is an older and weaker type of security. If your router still uses WEP, choose WEP in the generator and think about updating your router settings to WPA2 if you can. An open network has no password at all. Choose No password for an open network, but remember that anyone nearby can join an open network, so only use it for public guest access and never for a network that holds private files or devices.

If you are not sure which type your network uses, look at the WiFi settings on a phone that is already joined, or check the label on your router. In most cases, home networks in the United States, the United Kingdom, Canada and Australia use WPA2.

Keep your WiFi safe when you share it

Sharing your WiFi with a QR code does not make it less safe than typing the password, but a few simple habits help. Use a strong password with a mix of letters and numbers, and change it if you think it has been shared too widely. If your router can make a guest network, use that for visitors. A guest network keeps visitors on a separate network from your home computers, printers and smart devices. Change your guest password after a big event or after guests leave.

Do not print your main home password on a code and stick it in a public place. For a shop or cafe, use a guest network with its own password, and change it from time to time. Never share a QR code for a network that gives access to work systems or private files. If you change your WiFi password, make a new QR code, because the old code holds the old password and will stop working.

Printing your WiFi QR code

Print the code dark on a light background, with a white border around it. Do not print it very small, and do not stretch it. A code for a table card should be at least 4 cm wide. A code for a wall or a reception desk should be at least 8 cm wide so people can scan it from a normal distance. Use the SVG download for large prints, because it stays sharp at any size. If you put the code in a frame, avoid glare from a glass cover, which can block a scan. Test the printed code in the place where it will be used, in normal light, with more than one phone.

Troubleshooting a WiFi QR code

If a phone scans the code but does not join, check the password first. Type it again in the generator and make a fresh code. Check the network name too, including capital letters and spaces. If the code scans but nothing happens, the phone may need a scanner app, or the camera may need QR scanning turned on in its settings. On an iPhone, check Settings, Camera, and make sure Scan QR Codes is on. On Android, try Google Lens or a QR scanner app.

If the network is hidden, the code may not work on every phone. A hidden network does not show up in the list, and some phones need to be told to join it by hand. For best results, make the network visible. If you have both a 2.4 GHz and a 5 GHz network with the same name, some phones may join one band and have a weak signal. Give each band its own name if you see this problem. If the code works on one phone but not another, check that the second phone is up to date and try a scanner app.

WiFi QR codes vs sharing your password by text

Typing a password by hand is slow and easy to get wrong. A long password with capital letters, numbers and symbols is hard to read out, and one wrong letter wastes time. Sending the password by text message works, but then the password stays in chat history and can be forwarded. A QR code is faster for a group, it avoids typing mistakes, and it can be printed once and used many times. It is also clear for guests who do not speak the same language as the host. The code does not show the password on screen unless the phone shows it in the network settings, which is a small privacy bonus in a busy room.

FAQs

How do I make a QR code for my WiFi?

Type your network name and password in the generator above, pick your security type, and download the code. Guests scan it with their phone camera to join.

Is a WiFi QR code safe?

Yes, if you use a strong password. The code holds the same password you would type by hand. Use a guest network for visitors when you can, and change the password if it has been shared widely.

Do guests need an app to scan a WiFi QR code?

Most modern phones can scan it with the built-in camera. Some older Android phones may need a QR scanner app. iPhones scan WiFi codes in the camera app.

What if I change my WiFi password?

Make a new QR code. The old code holds the old password, so it will not join the network after a password change.

Can I use a WiFi QR code for a hidden network?

It may work on some phones, but hidden networks are less reliable with QR codes. Make the network visible for best results.

Does the WiFi QR code expire?

No. It is a static code, so it works as long as your network name and password stay the same. It never expires and there is no fee.
