WiFi QR code
WiFi QR code: your customers connect without typing the password
A WiFi QR code connects a phone to your network with a single scan, no need to read out the password. Enter the exact network name, the password and the security type. The iPhone camera and most Android phones recognize it without installing apps.

This is sample data. Replace it with your business details.
QR code reader: check where a code leads before you open it
Upload a photo or screenshot, paste it with Ctrl + V or use your camera. You’ll see the destination domain, Wi-Fi network or contact, with alerts if the link is shortened or not secure.
JPG, PNG or WebP. You can also paste a screenshot.
How do you customize a QR code without breaking it?
A branded QR code gets scanned more, but every design change eats into its reading margin. These rules keep the code readable:
- Minimum contrast of 4.5 to 1. Dark modules on a light background. Inverted colors fail in some readers.
- Logo at 25% or less of the width, with error correction H.
- Quiet zone of 4 modules around the code, with no text or borders on top.
- Visible corners. The three position squares are the first thing the camera looks for.
- Test before printing with two different phones and in the actual lighting.
How do you create a WiFi QR code?
4 steps, about two minutes.
Copy the network name
Type it exactly as it appears on your phone, including capitals and spaces.
Enter the password
Choose WPA/WPA2/WPA3 for most routers. If the network is open, choose No password.
Verify and download
The tool confirms the code contains your network. Test it with a phone before printing.
Put it where people can see it
At the bar, the front desk or each table. If you change the password, generate a new code.
What type of QR code does my business need?
It depends on what you want customers to do when they scan. This table sums up each type and where it works best.
| Type | What it opens when scanned | Where to use it |
|---|---|---|
| Link | Your website, Google reviews, Instagram or a PDF | Flyers, packaging, cards |
| A chat with you, with a pre-filled message | Delivery orders, quotes, appointments | |
| Menu | The restaurant’s digital menu | Tables, bars, food trucks |
| Card (vCard) | A contact card ready to save | Business cards, badges, booths |
| Wi-Fi | Access to your network without typing the password | Cafés, hotels, clinics, offices |
| Event | A reminder in the phone’s calendar | Openings, classes, weddings, trade fairs |
| Location | Google Maps with your address | Posters, invitations, ads |
Frequently asked questions
Does the WiFi QR code work on iPhone?
Yes. Since iOS 11, the camera recognizes Wi-Fi codes and shows a prompt to join the network.
Is it safe to share the password in a QR code?
Anyone who scans the code can connect. Use it with a guest network kept separate from the network your payment devices are on.
Do QR codes from QR Code Tools expire?
No. They are static QR codes: the information is stored in the code itself, so they work as long as the destination exists. They don’t depend on a subscription or an intermediate server.
Is it free, and do I need to sign up?
It’s free and requires no account. The code is generated in your browser and you can download it as PNG or SVG for commercial use.
What data do you store about me?
None. What you type, the logo you upload and the images you scan are processed on your own device and never sent to a server. Google ads shown on this site may use their own cookies, subject to your consent.
What size should I print a QR code?
Use the 10-to-1 rule: the code should be at least one tenth of the scanning distance. At 30 cm, 3 cm per side is enough; a poster seen from 2 m needs about 20 cm. If the code holds a lot of data, print it larger.
Can I put my logo in the center of the QR code?
Yes. When you add a logo, the tool raises error correction to level H, which tolerates up to 30% damage, and checks that the code still scans. Keep the logo at 25% of the width or less.
Which format should I download, PNG or SVG?
PNG for social media, WhatsApp and documents. SVG for print shops, banners and vinyl, because it’s vector and stays sharp at any size.
