WiFi QR Code Generator: Share Your WiFi With a Single Scan (Free)

Short answer: To make a WiFi QR code, choose the WiFi type in a QR code generator, enter your network name (SSID), password, and security type, then download and print the code. When a guest points their phone camera at it, the phone offers to join the network automatically — no password typing, no spelling out "is that a zero or an O?". On Qre.gg you can create one free in under a minute.

What a WiFi QR code actually does

A WiFi QR code stores three things: your network name (SSID), your password, and the security type (almost always WPA/WPA2). When scanned, the phone reads those details and shows a one-tap "Join Network" prompt. The guest never sees or types the password — they just tap and connect.

This is why cafés, Airbnbs, offices, and waiting rooms love them: you replace a sticky note full of Xq7$m… with a single sticker on the wall.

How to make a WiFi QR code (step by step)

1. Open the generator and pick the WiFi code type on Qre.gg.
2. Enter your network details:
   • Network name (SSID) — exactly as it appears, including capitals.
   • Password — copy-paste it to avoid typos.
   • Security — pick WPA/WPA2 (the default for almost all home and business routers). Choose "None" only for genuinely open networks.
3. Style it (optional). Set your brand colors and a "Scan to connect to WiFi" caption frame so people know what it does.
4. Download it as SVG for print (scales to any size with zero blur) or PNG for screens.
5. Print and place it where guests sit or wait (see placement below).

💡 Test it before you print a batch: scan your own code with a phone that is not already on the network, and confirm it connects.

Static vs dynamic: which WiFi code should you use?

This is the one decision that matters.

• Use a static code if your password rarely changes (a home guest network, a fixed office SSID). It's free, unlimited, and works even if the internet is down.
• Use a dynamic code if you rotate the password (short-term rentals, events, seasonal staff) — then you edit the password once and every printed sticker keeps working. New to the difference? Read Static vs Dynamic QR Codes.

Where to put your WiFi QR code

Keep it secure: 4 quick rules

A WiFi QR code is only as safe as the network behind it. Follow these:

1. Share a guest network, not your main one. Most routers let you run a separate guest SSID that can't see your private devices.
2. Rotate the password on rentals and events — and use a dynamic code so you don't reprint.
3. Don't post it on the public internet. A sticker on the wall is fine; a photo of the code on a public Instagram post hands your WiFi to the world.
4. Keep a quiet zone and high contrast so the code scans on the first try and people don't give up and ask for the password anyway.

What size should a WiFi QR code be?

Use the simple distance rule: minimum code size = scanning distance ÷ 10.

Always leave a blank quiet zone of about four modules around the code, use a dark code on a light background, and test-scan the final print under the room's real lighting.

Free vs paid

Most homes and single cafés are comfortable on the free plan. Property managers with many rentals, or chains rotating passwords across sites, usually want unlimited dynamic codes and advanced analytics.

Make your WiFi code now

Stop spelling out passwords. A WiFi QR code turns "what's the WiFi?" into a one-second scan — and a dynamic one means you never reprint when the password changes.
