Wi-Fi QR Code Generator

What is a Wi-Fi QR code?

A Wi-Fi QR code is a simple way to share network access without typing a password. The code stores the network name (SSID), password, and security type in a standard format. When someone scans it, their phone can join the network automatically. That makes it perfect for guest access, short stays, and public spaces where you want fast, low-friction onboarding.

Because the data is encoded directly in the image, a Wi-Fi QR code works offline and does not rely on a server. You can print it, save it as an image, or display it on a screen. The code is also easy to replace: when you change your Wi-Fi password or switch to a guest network, generate a new code and update the printout.

Examples of Wi-Fi QR uses

Wi-Fi QR codes remove the friction of typing long passwords. Common examples include:

• Guest networks for homes, rentals, and hospitality.
• Cafe, restaurant, or coworking Wi-Fi signage.
• Event check-in desks and meeting room displays.
• Office visitor access with a separate guest SSID.

How to use a Wi-Fi QR code

1. Replace the sample SSID and password with your real network details, then choose the correct encryption type for your router.
2. The preview updates instantly as you type. Check the canvas to make sure it looks sharp and high contrast.
3. Download as PNG for general use or SVG if you need a scalable format for signs, menus, or large prints.
4. Test the QR with a phone camera before you share it. Save a backup image so you can reprint quickly.

If you are setting up a guest network, use the guest SSID and password rather than your main network. Guests can then join without ever seeing your private Wi-Fi credentials.

Best practices before you share

Treat your Wi-Fi QR like a password card. Anyone who can scan the code can join the network, so share it intentionally. A few small choices can keep your network safer while still being convenient.

• Use WPA2 or WPA3 when available. Select WPA in the generator for both WPA2 and WPA3 networks.
• Create a guest network with its own password and separate it from your personal devices.
• Avoid WEP unless you have legacy hardware that cannot support newer standards.
• Rotate passwords regularly if you share access with many people.

If you need to display a Wi-Fi QR in public, consider limiting it to a guest SSID with internet-only access. That way, even if the QR spreads beyond your space, it does not grant access to your private network devices.

Where to display Wi-Fi QR codes

Wi-Fi QR codes are flexible. You can print them for tables, add them to a front desk sign, or display them on a TV in a meeting room. The goal is to put the code where guests naturally look when they need internet access.

• Homes: entryway, fridge, or a framed card on a shelf.
• Businesses: reception desk, menu stands, or receipts.
• Events: signage near check-in or on welcome screens.
• Hotels: room cards, lobby displays, or guest guides.

Print at least 3 inches wide so it scans quickly. High contrast (dark code on a light background) improves scan reliability.

Troubleshooting common scans

If a phone does not connect, first confirm the SSID and password are correct. Then verify the encryption type matches your router settings. A mismatch is the most common reason a scan fails.

Some older devices do not support Wi-Fi QR scans. In that case, keep the password visible next to the QR or include a short printed note so guests can join manually.
