WiFi QR Code Generator

Make a QR code your guests scan to join your WiFi in one tap, no typing the password. Supports WPA/WPA2/WPA3, WEP, and open networks. Free, no sign-up, runs entirely in your browser.

Enter your network name to generate the QR code.

This is a static QR code: your network details are encoded directly into the image. It works forever and needs no account, but it cannot be edited after printing and does not track scans.

Changing your WiFi password later means reprinting this static code. Want to update the details anytime without reprinting, or see how many guests connected? Use a Dynamic QR Code instead, editable destinations and scan tracking.

How WiFi QR codes work

A WiFi QR code encodes three things in a single standard string: your network name (SSID), the password, and the security type (WPA, WEP, or open). The format looks like WIFI:T:WPA;S:MyNetwork;P:mypassword;; and is understood by every modern phone camera.

When a guest points their camera at the code, the phone reads that string and offers a one-tap "Join Network" prompt. No spelling out a long password, no typos, no handing your phone around. It is the same technology behind the URL and text QR codes on our QR code generator, just with a WiFi payload.

Create your WiFi QR code in 3 steps

  1. Enter your network name exactly as it appears in your WiFi settings, including capitalization.
  2. Pick the security type and type the password (skip the password for an open network).
  3. Download the PNG and print it, or drop it into a sign, table tent, or welcome card.

Choosing the security type (WPA / WEP / open)

WPA / WPA2 / WPA3

The right choice for virtually every home and business router made in the last decade. If you are unsure, choose this.

WEP

An older, insecure standard. Only pick it if you are running legacy equipment that genuinely still uses WEP.

No password (open)

For networks with no password at all, common in cafes and waiting rooms. The code still auto-joins guests to the right SSID.

Hidden networks

If your SSID is not broadcast, tick "Hidden network" so phones know to look for it explicitly.

Print it for guests: cafes, Airbnbs, offices

A printed WiFi QR code saves everyone the awkward "what's the password?" exchange. Common placements:

  • Cafes & restaurants — a small table tent or a sticker by the counter.
  • Airbnbs & guest rooms — framed on the welcome card or inside the house manual.
  • Offices & reception — a "Guest WiFi" card so visitors self-serve without bothering the front desk.

Static vs dynamic WiFi QR codes

The code from this tool is static: the SSID and password live inside the image itself. That is perfect when your WiFi details rarely change, and it works with no account and no expiry.

But if you rotate your WiFi password regularly, or you want to know how many people actually scanned the code, a static code falls short, you would have to reprint it every time something changes. A dynamic QR code points to a short link you control, so you can update what it shows anytime without reprinting and see scan analytics. For anything that changes, dynamic is the better choice.

Best practices for reliable scanning

  • Double-check the SSID and password before printing, one wrong character means the code silently fails to connect.
  • Print at a decent size (at least 3 cm / 1.2 in wide) so phones lock on quickly.
  • Keep the white border around the code; the download already includes a quiet zone.
  • Test on both an iPhone and an Android before a large print run.

Frequently Asked Questions

How does a WiFi QR code work?▾
The QR code encodes your network name (SSID), password, and security type in a standard "WIFI:" string. When someone scans it with their phone camera, the phone offers to join that network automatically, so nobody has to type the password.
Which phones can scan a WiFi QR code?▾
Both iPhone (iOS 11 and later) and Android (version 10 and later) support WiFi QR codes natively from the camera app. On older Android phones you may need a QR scanner app, but the code itself follows the same universal format.
Is my WiFi password sent anywhere?▾
No. The QR code is generated entirely in your browser. Your network name and password are never uploaded, stored, or logged. The password is encoded directly into the image on your device.
Which security type should I choose?▾
Pick WPA for almost all modern routers (it covers WPA, WPA2 and WPA3). Choose WEP only for very old equipment, and "No password" for open networks with no password at all.
Can I change the password later without making a new code?▾
Not with a static WiFi QR code. The password is baked into the image, so if you change your WiFi password you must generate and reprint a new code. If you need to update details later or track scans, use a dynamic QR code instead.
