Type the name and password of your Wi-Fi network and download a QR code. Guests point their phone camera at it and tap to join, with no long password to read out. The password stays on your device: the code is made in your browser and nothing is uploaded or saved.
Made on your device: nothing is uploaded or saved. Free, with no sign-up.
Fill in the details and your QR code appears here.
Scan the code with your phone before you print it or share it. It is made on your device, and nothing you type is sent or saved anywhere.
A small printed code on the fridge, by the front door or in a guest room means nobody has to ask for the password. Print it with the network name above it for people whose phones cannot scan. If you change the password, make a new code: the old one keeps the old password.
Almost all modern phones. On an iPhone, the Camera app offers to join the network. On Android, the camera or Google Lens does. Older phones may need a QR reader app.
WPA covers WPA, WPA2 and WPA3, which is what nearly every router uses today, so keep it unless you know that yours is different. WEP is very old. Choose "No password" for an open network.
Anyone who can see or photograph the code can join the network, just as anyone who sees the password can. Put it where only guests can see it, and for a business or a PG consider a separate guest network that you can change.
That is fine: characters such as ; , : and " are written into the code correctly. Type the name and the password exactly, with the right capital letters, because Wi-Fi is case-sensitive.
No. The QR code is drawn in your browser from what you type, and nothing is sent to a server or stored, not even in your browser. Close the tab and it is gone, so download the code before you leave.
No. The code holds the information itself, so it works for as long as that information is right: a link that is still live, a Wi-Fi password that has not changed. There is no account behind it and no tracking, so it cannot be switched off.
PNG is a picture that works everywhere: use it for documents, social media and messages. SVG stays perfectly sharp at any size, so use it for banners, boards and anything printed large. Choose the Print size for PNG if you will print it.
At least 2 by 2 centimetres, and bigger if people will scan from a distance (about one tenth of the distance). Keep the white border around the code, and print dark squares on a light background. Always scan the printed code with a phone before you use it.
A QR code carries extra data so it can still be read when part of it is dirty or damaged. Higher levels survive more damage but make the code denser, with smaller squares. Medium suits almost everything; choose High for a print that may get scuffed.
