How to Create a WiFi QR Code (Free, 30 Seconds)

Typing out a WiFi password for every guest gets old fast. A WiFi QR code solves that. Guests point their phone camera at the code and connect in one tap. No app, no typing, no asking staff to repeat the password letter by letter. Here is how to make one in under a minute using a free tool.

What You Need

Not much:

• Your WiFi network name (SSID) -- exactly as it appears on your router
• Your WiFi password
• About two minutes

That is it. No software to install, no account to create.

How to Create Your WiFi QR Code (Step by Step)

Step 1: Open the WiFi QR Code Generator

Go to the WiFi QR Code Generator on GetFreeQR. The page loads a form with everything you need. No signup, no email required.

Step 2: Enter Your WiFi Details

Fill in three fields:

• Network Name (SSID): Type it exactly as it shows on your devices. Capitalization matters. If your network is called "HomeWiFi_5G" then you need to type it that way.
• Password: Double-check this. One wrong character and the QR code will not connect anyone.
• Security Type: Pick WPA2 for most modern routers. That covers about 95% of home and business networks. If you run an older setup, WEP is an option but you should probably upgrade.

Step 3: Customize the Look (Optional)

Change the foreground and background colors if you want the QR code to match your brand or decor. Pick a dot style. The preview updates in real time as you make changes.

You can also add a logo to the center of the code. The tool adjusts error correction automatically so the code stays scannable.

Step 4: Download

Click the download button and save your QR code as PNG for printing or SVG if you need to resize it later. Both formats are free with no watermark.

That is the whole process. Four steps, zero cost.

How to Print and Display Your WiFi QR Code

Print Size

Print it at least 5 x 5 cm (about 2 inches) so phones can read it comfortably from arm's length. If you are making a poster or wall sign, go bigger. A QR code that is too small will frustrate people trying to scan it.

Laminate the printout if it will sit on a counter or table where drinks might spill.

Where to Put It

The best spots depend on your setting:

• Cafes and restaurants: On tables, near the counter, or on the back of menus
• Hotels and Airbnbs: At the front desk, inside guest rooms, or on a welcome card
• Offices: In the lobby, conference rooms, or near the entrance
• Home: Near your router, on the fridge, or wherever guests tend to ask about WiFi

The goal is simple: put it where people naturally look when they want to connect.

Does It Work on iPhone and Android?

Yes. Both platforms have built-in QR code scanning in the camera app.

• iPhone: iOS 11 and later. Open the Camera app, point at the QR code, and tap the notification that appears.
• Android: Android 10 and later. Same process -- open Camera, point, tap.

Older phones might need a third-party QR scanner app, but that covers a small and shrinking share of devices.

Is It Safe to Share a WiFi QR Code?

The QR code contains your network name and password in encoded form. Anyone who scans it can connect to your WiFi network.

For a private home network, only share the QR code with people you trust. Treat it like you would treat writing the password on a sticky note.

For a cafe, hotel, or office guest network, displaying the QR code publicly is perfectly fine. That is exactly what guest networks are designed for.

If you want an extra layer of security, set up a separate guest network on your router. That way visitors get internet access without seeing your main network's devices.

What About Hidden Networks?

If your WiFi network does not broadcast its name (a hidden network), check the "Hidden network" box in the generator form. The QR code will still connect people automatically. They do not need to manually search for the network.

Frequently Asked Questions

Can I change my WiFi password without making a new QR code?

No. The password is baked into the QR code when you create it. If you change your router password, you will need to generate and print a new code. The old one will stop working.

Does the QR code need internet to work?

No. The QR code stores the WiFi credentials directly in the image. Scanning and connecting happens locally between the phone and the router. No server involved.

Does the QR code expire?

No. It works for as long as your network name and password stay the same. There is no time limit.

Can I use the same QR code at multiple locations?

Only if those locations share the exact same network name, password, and security type. Otherwise, you need a separate QR code for each network.
