Wi-Fi QR Generator

About the Wi-Fi QR Generator

The Wi-Fi QR Generator turns your network name and password into a scannable QR code. Guests open their camera, point at the code, and join your Wi-Fi without ever typing the password — useful for cafés, Airbnbs, offices, or just keeping a sticker on the fridge for visitors.

The QR code is built entirely in your browser using the standard ZXing Wi-Fi payload format. Your SSID and password are never sent to a server — they only exist on this page.

What you can control

• Network name (SSID) and security type (WPA/WPA2/WPA3, WEP, or open)
• Password with a show/hide toggle and a hidden-network flag
• QR size from 160 px up to 640 px for print or screen
• Code color and background, with a transparent option for placing the code on colored signage
• Module shape: classic squares, rounded squares, dots, diamonds, stars, plus signs, or hearts
• Corner pattern: matched to the module shape automatically, or set to squares, rounded, circular, or leaf
• An optional Wi-Fi icon in the center, with an adjustable size
• Optional label printed under the QR (e.g. "Scan to join HomeWiFi")
• Download as PNG, save straight to your phone's photos, print directly, or copy the raw Wi-Fi payload string

Styling without breaking the scan

Decoration is where most custom QR codes go wrong: a color that is too pale, or a center logo that swallows too many modules, produces a code that looks great and scans for nobody. Two things keep that from happening here. The code is generated at the highest error-correction level, so roughly 30% of it can be obscured and still read, which is what makes room for the Wi-Fi icon. And after every change the tool actually decodes its own preview the way a phone camera would, then tells you whether it passed and what to loosen if it did not. It is a real check on the rendered pixels, not a promise.

Common uses

• Guest Wi-Fi cards for short-term rentals and hotels
• Lobby or conference-room signage at offices and coworking spaces
• Café and restaurant table cards for customer Wi-Fi
• Home fridge sticker so visitors never have to ask for the password

Tips

• Use a larger QR size (400 px+) when printing on small cards
• Add a label so people know which network the code is for
• Keep the printed copy somewhere visible — but treat it like a key, not public info
• For a separate guest network, generate a second QR with that SSID and password

If you rotate your Wi-Fi password regularly (a good habit), reprint the QR each time so the sticker on your fridge stays in sync with the router.
