Wi-Fi QR Code Generator

• iPhone Open the Camera app, point at the QR, and tap the Wi-Fi notification. Works on iOS 11 and newer.
• Android Open the Camera (or Google Lens) on Android 10+, point at the QR, and tap the Connect prompt.

About the Wi-Fi QR Code Generator

The ReadBarcode Wi-Fi QR code generator turns your network name, password and security type into a scannable QR code that joins the Wi-Fi in one tap. Print it, stick it on the fridge, or drop it into a welcome guide — no more reading a 20-character WPA password out loud.

The encoded string follows the de-facto WIFI:T:…;S:…;P:…;H:…;; format that iOS Camera, Android Camera and most third-party QR readers recognise natively. Generation happens entirely in your browser using the open-source qrcode library — your password never leaves your device.

When to Use It

• Cafés, restaurants and co-working spaces sharing guest Wi-Fi.
• Airbnbs and short-term rentals — print one card for the kitchen.
• Conference rooms and event venues with rotating guest networks.
• Home networks when family or visitors keep asking for the password.
• Schools, classrooms and libraries with shared device carts.
• Retail backrooms where staff devices need to rejoin the network.

How It Works

1. Enter your network Type the SSID exactly as it appears in your router settings.
2. Pick security WPA covers WPA/WPA2/WPA3. Use WEP only for legacy networks, or No password for open Wi-Fi.
3. Enter the password 8–63 characters for WPA. Toggle the eye icon to verify what you typed.
4. Flag hidden networks Enable Hidden if your router does not broadcast its SSID.
5. Download PNG or SVG PNG for screens and quick prints. SVG for cards, signs and packaging.

What to Avoid

• Typos in the SSID — Wi-Fi names are case sensitive and a single wrong character means no connection.
• Sharing a QR for your main network with strangers — set up a separate guest SSID instead.
• Printing the QR very small without bumping error correction to Q or H.
• Inverting the colours (light QR on a dark background) — many phone cameras refuse to scan them.
• Embedding control characters or emoji that some routers strip — keep the SSID printable ASCII.

Tips & Tricks

• Print the QR alongside the SSID and password in text — useful for devices that cannot scan.
• Laminate it if it lives somewhere wet (kitchen, gym, pool).
• Rotate the guest password regularly and regenerate the QR — it takes 10 seconds.
• Test the QR with both an iPhone and an Android before you print a batch.
• Use the QR Code Reader on this site to confirm the payload decodes correctly.

Your Password Stays on Your Device

SSIDs and passwords are encoded locally with the open-source qrcode library. Nothing is uploaded, logged, or saved to our servers — close the tab and the credentials are gone.

How to Make a Wi-Fi QR Code for Guests

Enter your guest network's name and password in the generator above, then print the code where visitors can scan it.

1. Turn on a guest network in your router and note its name and password.
2. Type the name into Network name (SSID) and pick the security type the router uses.
3. Enter the password, and raise error correction to Q or H if the code will be printed small.
4. Scan the preview with a phone to confirm it joins, then download or print it.

This free Wi-Fi QR code generator has no username field, so it cannot cover WPA2-Enterprise networks that need a username and password.

Connect to Wi-Fi With a QR Code

Guests connect to Wi-Fi with the QR code in one scan: the phone reads the network name, security type and password and offers to join. Nothing is typed, so a long random password is as easy to share as a short one.

If joining fails, the code probably no longer matches the router's password or security type, so generate a new one. The QR code reader recognizes Wi-Fi codes and lists their fields, which shows what a printed code contains.

Generate a Wi-Fi QR Code Offline and Privately

This online Wi-Fi QR code generator builds the code in your browser, so once the page has loaded it needs no server. You can disconnect from the internet before typing the password and the preview still updates.

The Wi-Fi payload line under the preview shows the exact string inside the code, so you can confirm it holds only the details you entered.

Print a Wi-Fi QR Code Sign With Text

Click Print and choose the Wi-Fi card layout to print the code with the network name, password and security type beside it in plain text. Guests whose device cannot scan can type the details instead.

The card is credit-card sized and prints one per page or ten per sheet on Avery L7414 (A4) or Avery 5371 (US Letter) business-card stock. For a larger sign, choose Single label, set the width and edit the caption under the code. To encode a link or plain text instead, use the QR code generator.
