Plain QR Codes

Wi-Fi QR code generator

Create a Wi-Fi QR code that lets guests join your network without typing the password. The network name and password are encoded on your device and are not sent to us.

  • No account
  • No expiry
  • No watermark
  • Nothing uploaded

Step 1: Enter your content

This has to match your network name exactly, capital letters and all.

WPA covers WPA2 and WPA3 networks — phones handle the difference themselves.

Whatever you type is encoded into the QR code on this device and is not sent to Plain QR Codes.

Only check this if your network is hidden — meaning it never shows up in the list of nearby networks.

Step 2: Customize optional

Colors, shapes, logo and frame

1024 px is plenty for most printing. Changes the PNG and JPEG only — the SVG works at any size.

Advancedshapes, borders, frames and error correction

How much scuffing, smudging or fading the QR code can take and still work. Higher is tougher, but packs the dots in tighter.

4 squares wide

Phones need clear space around a QR code to spot it. Four is the safe minimum — printers sometimes call this the quiet zone.

Logo
Or pick a ready-made one
Symbols
Brands

Your image is processed on this device and never uploaded. Adding a logo also turns error correction up to maximum, so the QR code can survive having its middle covered.

Step 3: Your QR code

Your QR code appears here as you type.

SVG stays sharp at any size — use it for anything printed.

How to scan it

Both major phone platforms handle Wi-Fi QR codes with the built-in camera — no app required.

iPhone and iPad

Open the Camera app and point it at the code. A notification banner drops down offering to join the network; tap it, then tap Join. If nothing appears, check that Camera is allowed to scan QR codes in Settings → Camera.

Android

Open the Camera app and point it at the QR code, then tap the prompt that appears. On some phones this lives in the camera’s Google Lens mode instead. Android can also share a network you are already on: Settings → Network & internet → the network → Share, which generates a code for you.

A worked example

Suppose the café network is called Cafe Guest with the password flat-white-2026, secured with WPA2. Entering those puts this text inside the code:

WIFI:T:WPA;S:Cafe Guest;P:flat-white-2026;;

Special characters such as ;, ,, : and \ need to be escaped in the Wi-Fi QR format, and this generator handles that automatically — along with network names that could otherwise be misread by some scanners, such as one made only of the letters A–F and digits (Cafe, Beef).

Where to put it

  • Prefer a guest network. If your router supports one, a separate guest network lets visitors connect without sharing access to your primary network.
  • Size it for the distance. A card on a table can be small; a QR code on a wall people scan from across the room cannot. The size guide has a calculator.
  • Reprint when the password changes. The QR code encodes the password directly, so rotating it means generating a new code. That is the trade for it working without any service behind it.

Common questions

Does the QR code contain my actual Wi-Fi password?

Yes. A Wi-Fi QR code holds the network name and password as readable text — anyone who scans it, or who photographs it and decodes it later, gets the password. That is fine for a guest network on a café wall and a poor idea for your home network on a public-facing sign. The password is encoded on your device and never sent to us, but the code itself is not a secret.

Why won't my Wi-Fi QR code connect?

First check that the network name matches exactly, including capitalization and spaces — copy it from your router's admin page or your phone's network list rather than typing it from memory. Other causes include a mistyped password, a security type your device doesn't recognize, or a 5 GHz-only network being scanned by a device that can only see 2.4 GHz.

Should I pick WPA, WPA2 or WPA3?

Choose WPA — it covers WPA2 and WPA3 networks. The QR format has no separate WPA3 value in common use, and phones negotiate the actual security level with the router themselves. Only pick WEP if your hardware offers nothing else.

What is a hidden network?

A hidden network is one that never shows up in the list of nearby Wi-Fi. If yours is hidden, check the box — otherwise the phone will not know to go looking for it. Leave it unchecked for a normal network, or the connection may not work at all.
