WiFi QR Code Generator

The Easiest Way to Share Your Wi-Fi Password

Telling someone your Wi-Fi password out loud is awkward. Writing it on a sticky note is messy. Typing a 20-character WPA2 key on someone else's phone keyboard, especially one with a mix of symbols and numbers, leads to typos and frustration. A Wi-Fi QR code solves all of that. Print it once, stick it somewhere visible, and every guest — family, customers, colleagues, clients — connects instantly by scanning a single square with their camera. No verbal exchange, no sticky notes, no typing errors.

This tool generates a properly formatted Wi-Fi QR code from your network name (SSID) and password, entirely in your browser. Nothing you enter is sent to any server. Enter the details, download the image, and you are done.

How a Wi-Fi QR Code Actually Works

A Wi-Fi QR code encodes a plain text string in a specific format that both Android and iOS recognize as network credentials. The format looks like this: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;. The operating system reads this string when you scan the code and immediately offers to join the specified network, pre-filling both the SSID and the password. The user taps Join — that is the entire connection process.

Android has supported this natively since version 10 (released 2019). iPhone and iPad support it natively from iOS 11 onward. In other words, any reasonably modern phone will work without installing anything extra. The only exception is very old devices — Android 9 or earlier, or iOS 10 or earlier — but these represent a small and shrinking share of devices in use today.

What to Do After Generating the Code

Once you have downloaded the image, the most common approach is printing it in a frame or laminating a card. For homes, a 9 × 13 cm card placed near the router or on the refrigerator works well. For cafes and restaurants, a small printed card in a table stand is standard. Hotels often include it on a welcome card in the room.

The image you download is a square PNG at a reasonable resolution. It will print sharply at up to roughly A5 size. If you need it larger than that — for a poster, say — regenerate at the largest available output size or use a vector-capable tool to scale it up without softening.

Before printing, test the code with your own phone. Open the camera app, frame the code, and check that the correct network name appears in the connection prompt. It takes ten seconds and eliminates the possibility of guests scanning a code that connects them to the wrong network or fails entirely because of a password typo.

Security Considerations Worth Knowing

A Wi-Fi QR code is a permanent record of your password in image form. That is worth thinking about before you decide where to put it.

For home networks, the risk is generally low. A photo of your printed code could theoretically give someone your password, but they would still need to be physically within range of your router to use it. The convenience gain for regular guests is usually worth the theoretical risk, especially if your home network is already behind standard WPA2 or WPA3 security.

For business environments, the calculus is different. If your guest network is separate from your operational network — which it absolutely should be in any business setting — posting the guest Wi-Fi QR code publicly is fine. You do not want strangers on the same network as your point-of-sale system, printers, or internal servers. A guest VLAN with internet-only access, paired with a visible QR code, is exactly the right setup: convenient for customers, isolated from business-critical systems.

If you change your Wi-Fi password, you will need to generate a new QR code and replace any printed copies. This is one of the few maintenance tasks involved — but since most people rarely change their home Wi-Fi password, it is unlikely to be a frequent concern.

WPA, WPA2, WEP: Which Setting to Choose

This tool asks you to select your network's encryption type. Here is what each option means and which one you almost certainly need.

WPA/WPA2 is the right choice for virtually every network set up in the last fifteen years. WPA2 is the standard that replaced WEP in consumer routers, and WPA3 is its modern successor. If your router was purchased after 2006 or so, it uses WPA2 unless you have explicitly changed it. Select this option.

WEP is an older encryption standard from the 1990s that has been considered cryptographically broken since the early 2000s. If your router is still using WEP, your network is insecure regardless of password strength — updating the encryption type in your router's admin panel should be a priority. Some QR code format parsers handle WEP differently, which is why this tool exposes it as a separate option.

None (open network) is for networks with no password. Some public-facing setups — airports, parks, free public hotspots — operate this way. The QR code for an open network simply encodes the SSID with no credential, and phones will join it automatically on scan.

Good Places to Display a Wi-Fi QR Code

The right placement depends on who you are making it for. A few scenarios that come up regularly:

Cafes and co-working spaces typically mount it next to the counter, at eye level, where it is seen naturally when ordering or checking in. Some put a smaller version on each table so guests can connect from their seats without asking staff.

Short-term rental properties — Airbnb, Vrbo — often include a printed welcome card with the Wi-Fi code, check-out instructions, and local recommendations. Guests appreciate this because it means one less message thread asking for the password.

Home setups vary, but a small laminated card on the router itself or on the inside of a kitchen cabinet door keeps it accessible to family members and occasional guests without being prominently displayed to anyone walking past a window.

Offices with a separate guest network benefit from having the code displayed in reception or meeting rooms so visiting clients or contractors can connect without involving IT.

Your Password Never Leaves Your Browser

Wi-Fi passwords are sensitive credentials. Entering yours into a random web form that sends data to a remote server is a real risk — the kind of thing that ends up in credential dumps. This tool is different by design. The QR code is generated entirely by JavaScript running in your browser. Your network name and password are processed locally and never transmitted anywhere. Once you close the tab, there is no trace. The downloaded image contains the encoded data, so store it and share it accordingly.
