Wi‑Fi QR Code Generator

iPhone (iOS 11+): Open the Camera app, point it at the QR code, and tap the yellow notification banner that appears at the top of the screen. Your phone will automatically join the network.

Android (10+): Open the Camera app, point it at the QR code, and tap the Wi‑Fi network pop-up. On some Android devices, you may need to use Google Lens or the built-in QR scanner in Quick Settings.

Older devices: Download a free QR scanner app (such as Google Lens, QR & Barcode Scanner) and scan the code.

This generator supports all major Wi‑Fi security protocols: WPA3 (the latest and most secure), WPA2 (widely used and recommended), WPA/WPA2 mixed mode, WEP (legacy, not recommended due to weak security), and Open networks with no password. We recommend using WPA2 or WPA3 for optimal security. Note that WEP is now considered insecure and should only be used for legacy device compatibility.

The QR code stores your Wi‑Fi password in plain text within the encoded string. Anyone who scans the code or inspects the QR data can read your password. We recommend: (1) Only share the QR code with trusted individuals, (2) Avoid posting it publicly online, (3) Consider creating a guest network with a separate password for visitors, (4) Change your Wi‑Fi password periodically if you've shared the QR code widely. Never embed sensitive network credentials in publicly accessible locations.

Yes! Toggle the "Hidden Network" switch in the form. This adds the H:true parameter to the Wi‑Fi connection string, which tells the scanning device that the SSID is not being broadcast. However, note that hidden networks are not more secure — they only hide the SSID from casual discovery. A determined attacker can still detect them. Also, some older devices may have trouble connecting to hidden networks via QR code.

Special characters like ; : , and \ are automatically escaped in the Wi‑Fi QR code format to ensure the barcode scans correctly. For example, a semicolon in your SSID becomes \; in the encoded string. Our tool handles all escaping automatically, so you don't need to worry about it. If you're manually crafting a Wi‑Fi string, remember to escape these four characters with a backslash.

The QR code itself never expires — it's a static encoding of your network credentials. It will continue to work as long as your Wi‑Fi network's SSID, password, and security type remain unchanged. If you change your Wi‑Fi password or rename your network, you'll need to generate and distribute a new QR code. The printed or digital QR code has no built-in expiration mechanism.

Absolutely! Click the "Print" button to open a print-optimized view, or download the SVG format for the best print quality — SVG is a vector format that scales to any size without losing clarity. For PNG downloads, we recommend the 1200×1200 option for printed materials. When printing, ensure the QR code is at least 2 × 2 cm (0.8 × 0.8 inches) for reliable scanning. Use a matte finish rather than glossy paper to reduce glare.

iOS: Native support since iOS 11 (2017) via the Camera app.
Android: Native support since Android 10 (2019) via the Camera app or Google Lens.
Windows: Not natively supported; use a third-party QR scanner app.
macOS: Not natively supported for Wi‑Fi connection via QR.
Smart TVs & IoT devices: Some smart devices can scan QR codes during setup. Check your device's documentation.
Most modern smartphones (2019 and newer) support Wi‑Fi QR code scanning out of the box.

Yes. According to the Wi‑Fi Alliance specifications: SSID can be up to 32 bytes (usually 32 ASCII characters, though some special characters or emoji may use more bytes). WPA/WPA2/WPA3 passwords must be between 8 and 63 ASCII characters. WEP passwords have stricter limits: typically 5 or 13 ASCII characters (or 10 or 26 hexadecimal digits). Our tool enforces these limits to ensure compatibility with all devices.
