WiFi QR Code Generator

Create and print a WiFi QR payload for a 1–32-byte SSID, WPA/WPA2, legacy WEP, or an open network, with explicit plaintext-credential warnings.

Use this result well

Inputs that matter
An exact 1–32 UTF-8-byte SSID, WPA/WPA2, legacy WEP, or open-network label, required secured-network password, and hidden-network flag
Output to expect
A current browser-rendered WiFi QR code plus PNG, print, and explicit plaintext-payload copy actions
How it works
Reserved WIFI delimiters are escaped before encoding WIFI:T:…;S:…;P:…;H:…;; at QR correction level M
  • The QR, copied payload, screenshots, downloads, and printouts disclose recoverable plaintext credentials; distribute them like the password itself.
  • Scanner, operating-system, network-mode, policy, and captive-portal support varies, so test the final artifact on target devices.

Choose your path

Built around the job you need to finish

Create a current WiFi QR artifact from validated fields while making plaintext credential exposure and scanner compatibility explicit.

Home guest-network owner

Share a separate guest SSID without dictating its password.

Enter the exact SSID/password/security/hidden flag, then download or print and scan-test.

Uses a guest network, understands the QR reveals the password, and verifies the final artifact.

Small venue operator

Prepare a repeatable printed connection card.

Stay within the 32-byte SSID limit, render the code, print it, and test representative devices.

Treats the print as public credentials and rotates/removes it when access should end.

Security-conscious user

Avoid accidental storage or misleading protection claims.

Review local-session behavior and explicit copy/download/screenshot exposure before sharing.

Does not encode private administrative credentials or assume browser-local rendering makes shared artifacts secret.

Reference & details

How it works

WIFI Payload

Reserved backslash, semicolon, quote, comma, and colon characters are escaped before assembling WIFI:T:…;S:…;P:…;H:…;;. Compatibility remains scanner-dependent.

Client-Side Generation

The component calls the loaded QR library in the browser and does not intentionally persist the fields. This is a limited implementation statement, not a guarantee about browsers, extensions, screenshots, or copied/downloaded artifacts.

Validation and Export

SSID input is measured as UTF-8 and limited to 32 bytes; secured modes require a password. Render and export failures are displayed, and PNG/print actions remain disabled until a current render succeeds.

Example Scenarios

Create a separate guest-network code, scan-test the print, display it only to intended visitors, and rotate credentials when access should end.

A cafe uses an isolated guest network and validates the actual printed code across representative devices before putting it on tables.

An organizer treats the QR as public credentials, coordinates network capacity and expiry separately, and avoids encoding private administrative access.

FAQ

The tool escapes reserved WIFI payload characters and encodes the exact SSID, security label, password, and hidden-network flag. A compatible scanner may offer to join; connection is not guaranteed.

The panel emits WPA for WPA/WPA2-style credentials, WEP for legacy networks, and nopass for open networks. It does not expose an enterprise-authentication or distinct WPA3 payload mode.

No. Camera, operating-system, security-mode, captive-portal, and device-policy support varies. Scan-test the final image or printout on the devices you expect guests to use.

This panel does not intentionally save credentials in localStorage. The password is still present in the page state, QR pixels, copied WIFI payload, downloads, printouts, screenshots, and any browser or device facilities involved in those actions.

Yes. Download PNG or print from the panel, then scan-test the actual output. Treat the printout like the password itself and remove or replace it when access should end.

About WiFi QR Code Generator

Enter the network name exactly, choose WPA/WPA2, legacy WEP, or open access, and add the password when required. The QR is rendered in this tab, but it contains recoverable plaintext credentials and must be scan-tested before sharing.
