How to Create a WiFi QR Code (Free, in Under a Minute)

June 12, 2026

Reading a WiFi password out loud — twice, with the “capital B, number zero” routine — is a small ritual nobody enjoys. A WiFi QR code replaces it entirely: guests point their camera at a printed code and their phone offers to join the network.

Here’s how to make one in under a minute.

Step 1: Find your exact network details

You need three things:

Network name (SSID) — exactly as it appears in your WiFi settings, including capitalization.
Password — also case-sensitive.
Security type — almost every modern router uses WPA/WPA2/WPA3. Only very old networks use WEP.

If you’re unsure of the security type, choose WPA — it’s correct for nearly everyone.

Step 2: Generate the code

Open our free WiFi QR code generator, enter the three details, and the code appears instantly. Everything happens in your browser — your password is never sent to any server, which is exactly what you want for a credential like this.

Step 3: Download and print

Download the code as PNG (fine for most printing) or SVG (if you’re making a larger poster or handing it to a designer). Print it at least 3 × 3 cm so cameras can focus easily, and keep dark-on-light colors for reliable scanning.

Good spots: a frame on the bookshelf, the fridge door, a guest-room nightstand, a café table tent, or the reception desk.

How scanning works for your guests

iPhone (iOS 11+): open the Camera app, point at the code, tap the “Join network” banner.
Android (10+): same — the built-in camera recognizes WiFi codes. On older Android versions, Google Lens does it.

No app installs, no typing, no mistyped passwords.

One thing to remember

The code encodes the password at the moment you create it. If you later change your WiFi password, just generate a fresh code — it takes seconds and the generator stores nothing, so there’s no account to update.
