Have you ever read a long Wi-Fi password out loud to a guest? One wrong letter and they start over. The WiFi Password QR Generator turns your network details into a scannable QR code and a plain WIFI text string.
It is made for home hosts, cafe owners, and small offices. You type the network name and password, pick the security type, and the code updates as you type. Guests point a phone camera at it and join.

What the Tool Creates
The tool builds one Wi-Fi QR code from four inputs. Everything runs in your browser, so no network details are sent to a server.
- Live QR Code: a black and white image that encodes your network details.
- WIFI URI String: the raw text behind the code, in the format phones understand.
- Network Name Card: shows the SSID you typed, or "None" when the field is empty.
- Encryption Card: shows a friendly label for the security type, such as WPA/WPA2.
- Format Card: a fixed label that reads "WIFI: URI".
- Download QR Code Image saves a PNG, and Copy WiFi URI String copies the text.
How to Use It, Step by Step
- Type the Network Name (SSID). The sample value is MyHomeWiFi.
- Type the WiFi Password. The sample value is SecretPassword123.
- Pick a Security Type: WPA / WPA2 / WPA3, WEP, or None for an open network.
- Check Network SSID is Hidden only if your router does not broadcast its name.
- Watch the QR code and the text string update after each change.
- Press Download QR Code Image to save the PNG, or Copy WiFi URI String to copy the text.
The WiFi QR Format
A Wi-Fi QR code is not magic. It holds a short text string that both Android and iOS cameras know how to read. The tool joins your inputs into that string and draws it as a code.
WIFI:S: NameT: SecurityP: PasswordH: Hidden=QR Code
- S is the network name, and T is the security type.
- P is the password, and H is true or false for a hidden network.
- The tool writes the name first, then type, password, and the hidden flag.
- Special characters in the name or password get a backslash in front of them.
- The escaped characters are backslash, semicolon, comma, double quote, and colon.
Worked Example
Priya shares her home network with a weekend guest. She keeps the sample name MyHomeWiFi and password SecretPassword123. She leaves the type on WPA and the hidden box unchecked.
| Field | Value Entered | In the String |
|---|
| Network Name (S) | MyHomeWiFi | MyHomeWiFi |
| Security (T) | WPA | WPA |
| Password (P) | SecretPassword123 | SecretPassword123 |
| Hidden (H) | Unchecked | false |
The full string becomes WIFI:S:MyHomeWiFi;T:WPA;P:SecretPassword123;H:false;;. The two semicolons at the end close the record. The Encryption card shows the friendly label WPA/WPA2.
Now take Marcus, who runs a cafe called Bean & Co with the password Table;7. The semicolon in the password gets escaped. His string reads WIFI:S:Bean & Co;T:WPA;P:Table\;7;H:false;;, so a scanner reads the password as Table;7.
How to Read the Results
The QR Code is the image guests scan. It carries the exact details you entered, including the password.
The Network Name card echoes your SSID so you can confirm the spelling. If you leave the field blank, it reads "None" and the tool shows a required message instead of a code.
The Encryption card shows a plain label for your choice. It reads WPA/WPA2, WEP, or None, so an open network never shows a raw code word.
Download QR Code Image saves a file named wifi-qr-code.png. Copy WiFi URI String places the text on your clipboard, then the button shows a short confirmation.
Where to Place the Code and Keep It Safe
A printed code works well on a table tent, a fridge, or a framed card near the door. Keep it large enough that a phone camera can focus from a foot away.
Treat the code like the password itself. Anyone who scans it can join your network and read the password in plain text. Share it only with people you trust.
For a guest network, pick a separate name and a fresh password. You can build one with the random password generator, then test its strength in the password strength checker.
To confirm the code before you print it, read it back with the QR code reader. If you want a slightly different layout, the basic Wi-Fi QR tool covers the same job. Browse more utilities in the developer tools hub.
Limitations and Assumptions
- The network name is required. An empty name shows a message and draws no code.
- When you pick None, the password field is disabled and left out of the code.
- The Encryption card shows a friendly label, so an open network reads None.
- Very long names or passwords can exceed the code capacity. The tool clears the image and warns you, and the text string stays copyable.
- The password appears as plain text on screen, so shield it from onlookers.
- If the clipboard is blocked, the copy button falls back and tells you when it fails.
FAQs About the WiFi Password QR Generator
Do I Need an App to Scan the Code?
No. Most modern iPhone and Android cameras read Wi-Fi codes on their own. Older phones may need a free QR reader app from the store.
Does the Field Order Matter?
No. Phone scanners read each label by name, not by position. So the order of the segments does not change the result for the scanner.
Can I Make a Code for a Hidden Network?
Yes. Check the Network SSID is Hidden box. The string then sets H to true, which tells the phone to search for the name.
Why Is My Password Shown in Plain Text?
The field is a normal text box so you can confirm the spelling. Remember that the QR code and the copied string both carry the password as written.
Is My Network Data Sent Anywhere?
No. The code is built in your browser with a local script. The details stay on your device unless you share the image or the string.
What Does the Backslash in My Password Mean?
It is an escape mark for special characters. A scanner removes the backslash and reads the real character, so a saved Table\;7 becomes Table;7.
