Wi-Fi QR Code Generator

Last reviewed: 9 November 2026 by QRKit Editorial Team

A Wi-Fi QR code carries a network name, security type and password in the standard WIFI: format. Modern iPhone and Android cameras can offer to join the network after scanning, which saves guests from typing long passwords.

Use it for a guest network rather than your main network, and place the printed code where only visitors can see it. Anyone who can photograph the code can read the password.

What this QR code stores: The QR code stores a WIFI: string with the SSID, security type, password (unless the network is open) and an optional hidden-network flag. The password is readable by anyone who decodes the code.

The exact name shown in the Wi-Fi list. Maximum 32 characters.

8–63 characters for WPA. Leave blank for an open network.

Adds the hidden-network flag. Some devices ignore it and require manual setup.

Style and output

PNG pixel size. SVG scales without losing quality.

Higher levels survive damage but create a denser pattern.

Available in PNG and SVG. Place the code on a light, plain surface.

Contrast is 21.0:1 — good for scanning.

Centre logo (optional)

PNG, JPEG or WebP · max 1.5 MB

A logo covers data modules. Keep it small, use a high-contrast image and always test the finished code.

PNG and SVG files are created in your browser. The selected logo, if any, is included in the file.

Test first: scan the finished code with at least one phone camera before you print, laminate or publish it.

Before you print or share

  • WPA/WPA2 and open networks are the most reliable choices. WEP is obsolete and should be replaced rather than shared.
  • Some devices still require manual setup, especially for hidden networks or enterprise Wi-Fi. Test with both iPhone and Android before relying on the code.

Practical guidance for this generator

Example: Enter Guest-Cafe, choose WPA, type the current guest password, then scan with a phone that has never joined the network.

Common mistakes

  • Mistyping the SSID, which is case-sensitive.
  • Sharing the main office network instead of a guest SSID.
  • Assuming the hidden-network flag works on every phone.

Testing checklist

  • Scan with a device that is not already connected.
  • Confirm the join prompt appears and the password is accepted.
  • Repeat on one iPhone and one Android phone.

When to choose a different tool

Use a guest network and printed instructions instead if you cannot share the password publicly.

How to create this QR code

  1. Enter the exact network name and security type.

  2. Enter the password (or choose an open network), then generate the code.

  3. Scan it with a phone that is not already on the network, confirm the join prompt, and print.

Planning a guest Wi-Fi code

A Wi-Fi code is only as safe as the network it joins. Put guests on a separate network or guest SSID, rotate the password between events, and treat every printed copy as public.

The SSID is case-sensitive and must match exactly. If the network is hidden, some phones will still require manual setup even after scanning.

  • Prefer WPA2 or WPA3; replace WEP rather than sharing it.
  • Place the code where only visitors can see it.
  • Test with a phone that is not already connected.
  • Change the password and reprint when guests leave.

Frequently asked questions

Is the Wi-Fi password visible in the QR code?

Yes. The password is encoded in the pattern and can be recovered by anyone who scans or decodes it. Treat a Wi-Fi QR code as public within the area where it is displayed.

Why does my device not offer to join?

Support varies. iPhone cameras generally recognise WIFI: codes, while some Android scanner apps only show the raw text. Try the built-in camera app and check the security type and SSID spelling.

Can I hide the network name?

You can add the hidden flag, but hiding an SSID is not a security measure and support for the flag is inconsistent. Use a strong password and WPA2/WPA3 instead.
