Is it safe to make a WiFi QR code?

Yes, with some caveats. Your WiFi password is never sent to any server when using our browser-based generator - the QR code is created locally on your device. The QR code itself contains your password in readable form, so only share printed copies with trusted guests, just as you would share a written password.

Why is my WiFi QR code not working?

The most common causes are: wrong SSID (network name is case-sensitive and must match exactly), wrong password (case-sensitive), wrong security type selected (most home and business WiFi uses WPA/WPA2), or a hidden network without the Hidden checkbox ticked. Regenerate the QR code after verifying each field.

What size should I print my WiFi QR code?

For table cards (A6 or smaller), download at 512px PNG. For A5 or A4 prints, download the SVG version which scales without pixelation. A QR code should be at least 2.5cm x 2.5cm when printed to scan reliably from arm's length.

How to Create a WiFi QR Code Free: Step-by-Step Guide for Restaurants and Homes

A WiFi QR code lets anyone connect to your network by pointing their phone camera at a printed sign - no typing, no staff interruptions, no awkward conversations about where the password is. It takes about two minutes to create and costs nothing. Here is how.

What a WiFi QR Code Does

A WiFi QR code encodes your network name (SSID), password, and security type in a format that phones understand natively. When a guest scans it:

iPhone (iOS 11 or later): the Camera app shows a prompt at the top of the screen to join the network. One tap and they are connected.
Android (Android 10 or later): the Camera app detects the WiFi QR code and shows a Connect button.
Older devices: most QR scanner apps also support WiFi QR codes.

No app download is needed for modern phones. No typing. No asking staff for the password. The guest is connected in under 10 seconds from scanning.

Who Needs a WiFi QR Code

Cafes and restaurants - Put one on each table. Customers connect without bothering staff. Works for small kopitiam stalls in Singapore just as well as for large restaurants.
Hotels and Airbnb hosts - Frame it and leave it on the desk. Your guests connect the moment they arrive. Guests consistently mention WiFi in reviews, and making it easy earns you points.
Offices and coworking spaces - Put it in meeting rooms and reception. Visitors connect quickly without waiting for IT or reception staff.
Events and conferences - Print on your event program or put on screen. Hundreds of attendees can connect without creating a bottleneck.
Home - Frame it in your living room. When family or friends visit, they connect without asking you to spell out your 20-character password.

Step by Step: Create Your WiFi QR Code

Open the WiFi QR Code Generator. Go to our free WiFi QR code generator. No account or signup needed.
Enter your network name (SSID) exactly. Copy it from your router settings or from another device that is connected. It is case-sensitive: "HomeNetwork" and "homenetwork" are different.
Enter your WiFi password exactly. This is also case-sensitive. Click the eye icon to see what you are typing. A single wrong character means the QR code will not work.
Select the security type. Most home and business routers use WPA/WPA2. Select WEP only if you have an older router. Open networks with no password select None.
If your network does not broadcast its name, tick "Hidden network". Most networks are not hidden - leave this unchecked if you are unsure.
Download the QR code. Use PNG at 512px for printing. Use SVG for larger prints. Your QR code is ready.

How to Display Your WiFi QR Code

Print on A6 card, laminate, and place on tables. This is the most common setup for cafes and restaurants. Lamination makes it water-resistant.
Frame it. A simple IKEA frame with a printed A5 sheet looks professional and lasts for years. Put it in Airbnb listings, hotel rooms, and home living rooms.
Add to your menu or welcome card. If you print menus anyway, put the QR code on the back or a corner.
Stick it on the fridge for home use. Guests who come to the kitchen will find it immediately.

Download the SVG version if you plan to print larger than A5. SVG is a vector format that scales to any size without becoming blurry. PNG looks sharp up to about 10x10cm at 512px.

Troubleshooting: Why Your QR Code Might Not Work

If scanning the WiFi QR code does not connect the phone, check these in order:

Wrong SSID. The network name must match exactly, including capital letters, spaces, and special characters. Check it against your router's admin page or a connected device.
Wrong password. The password is case-sensitive. Re-enter it carefully. Use the show/hide toggle to verify what you typed.
Wrong security type. If your router uses WPA3 and you selected WPA/WPA2, try both. Most modern routers accept WPA/WPA2 as a backwards-compatible choice.
Hidden network without the checkbox. If your network does not broadcast its SSID, tick the "Hidden network" checkbox and regenerate.
Old Android phone. Android 10 and later support WiFi QR codes natively. Older versions need a QR scanner app that specifically supports WiFi codes.

Is It Safe to Share a WiFi QR Code?

Sharing a WiFi QR code is the same as sharing your WiFi password - the password is encoded in the QR image and anyone who scans it can read it with the right app. This is fine for restaurant guests and Airbnb visitors, the same people you would give the password to anyway.

What is safe: our generator never sends your password to any server. The QR code is created entirely in your browser. No one at IWantFreeQRCode.com has access to your WiFi password.

What to consider: do not post your WiFi QR code publicly online (social media, websites) if you want to restrict access to paying customers or guests only. For high-security needs, use a separate guest network with a different password.

If you change your WiFi password, you need to generate a new QR code. The old one will stop working immediately. Keep the generator bookmarked for quick regeneration.
