WiFi QR Code Generator

Make a free WiFi QR code so guests can join your network without typing the password. Enter the network name and password, choose the security type, and mark a hidden network. The password stays in your browser: it is only drawn into the code. Download SVG, PNG, PDF or EPS.

The password stays in your browser: it is only drawn into the QR code, never sent anywhere.

Tick this if the network does not broadcast its name.

Printed in the file with the barcode, outside the quiet zone, in Helvetica or Courier so it looks the same in every format.

Bar width reduction0 mil

Makes each bar thinner by this amount, to make up for ink that spreads on paper. Ask your printer for the value, or leave 0 for laser and thermal printing.

Rotation and backgroundNew0° · Filled

Rotation

In the preview, a checkered pattern shows the transparent areas. Print a transparent barcode only on a white or very light surface: scanners need the light quiet zone around it.

Margin and borderNew0 mm · no border

The margin is blank space outside the quiet zone, for cutting; the border is drawn at the outer edge. Both count in the print size.

Link tracking (UTM)NewOff

Adds utm_ parameters to the link so analytics can tell where a scan came from. A longer link makes a denser code.

      How to Create a WiFi QR Code

      Enter the network details exactly as your router shows them, then download and print the code.

      1. Type the network name (SSID) exactly, including capitals and spaces.
      2. Choose the security type and type the password; choose None for an open network.
      3. Tick Hidden network if your network does not broadcast its name.
      4. Download the code, print it, and test it with a phone before putting it up.

      WiFi QR Code Fields

      A Wi-Fi QR code holds the network name, the security type, the password and whether the network is hidden.

      How a WiFi QR Code Works

      The code holds the network details in the WIFI: format that ZXing documented, and a phone that recognizes it asks before joining.

      Wi-Fi QR code for the example network Cafe Guest with WPA security and the password coffee-2026.
      The example network Cafe Guest with WPA: WIFI:T:WPA;S:Cafe Guest;P:coffee-2026;;

      Special Characters

      A backslash goes before \ ; , " and : in the name and password, and a name or password that could be read as hex is put in double quotes. The generator does this for you, and the Encoded content shows the result.

      Wi-Fi QR code for the example network Cafe;Guest with the password tea:time, where the semicolon and the colon are written with a backslash.
      Cafe;Guest and tea:time, written as Cafe\;Guest and tea\:time in the code.

      Phones That Read It

      ZXing lists Android and iOS 11 or later as reading this format. On an iPhone, the Camera app reads QR codes: hold it over the code and tap the notification that appears. Control Center also has a Code Scanner.

      Is a WiFi QR Code Safe?

      The password is written in the code in plain text, so anyone who scans it, or reads it with a scanner app, can see it.

      Good Practice

      • Guest network: share a guest network, not the one your own devices use.
      • Placement: put the code where only your guests can scan it.
      • Password changes: print a new code whenever you change the password.

      Why a WiFi QR Code Does Not Connect

      Most failures come from a detail that differs from the router's settings.

      What to Check

      • Network name: names are case-sensitive: Cafe Guest is not cafe guest.

        Wi-Fi QR code for the example network Cafe Guest, with the name written exactly, capitals and space included.

      • Security type: choose WEP only for old WEP networks; most networks use WPA or WPA2.

        Wi-Fi QR code for an example open network Cafe Guest, with no password.

      • Hidden networks: tick Hidden network if the name is not broadcast.

        Wi-Fi QR code for the example hidden network Cafe Guest, with H:true so phones look for it.

      Frequently Asked Questions

      Is My WiFi Password Sent Anywhere?

      No. The code is built and drawn in your browser; the password is only written into the QR code itself.

      Does a WiFi QR Code Work on iPhone?

      ZXing lists iOS 11 or later as reading Wi-Fi codes, and the iPhone Camera reads QR codes. Test your printed code with the phones your guests use.

      What If My Network Uses WPA3?

      The format has a WPA type for WPA and WPA2 networks. Test the code with your own devices before relying on it for a WPA3-only network.

      Do I Need a New Code When I Change the Password?

      Yes. The password is in the code, so the old code stops working when the password changes.

      Can I Make a Code for an Open Network?

      Yes. Choose None as the security type; the code then holds only the network name.

      Is the WiFi QR Code Generator Free?

      Yes, with no account, watermark or download limit.
