WiFi QR Code

How to use WiFi QR Code

1. 1

   Enter your network name (SSID) and password.

2. 2

   Pick the security type — WPA is the usual one.

3. 3

   Scan the live preview with your phone to check it connects.

4. 4

   Download the QR as PNG or SVG and print it or frame it.

Share your WiFi with a code instead of spelling out the password

A WiFi QR code generator solves a small daily annoyance: a guest asks for the WiFi, and you either read out a 16-character password twice or hand over your phone. A WiFi QR code carries the network name, security type and password in a format that every modern phone recognises. Point the camera at it, tap the prompt, and the phone joins the network — no typing, no misread letters, no password on a sticky note.

This page builds that code from three fields: the SSID (the network name as it appears in the WiFi list), the password, and the security type. Tick the hidden-network box if your router does not broadcast the name. The preview updates as you type, so you can scan it with your own phone before printing anything.

Security type, hidden networks and other details that break codes

Almost every home and office network today uses WPA2 or WPA3, and one option covers all three WPA generations — pick it unless your router is very old. WEP exists for the handful of legacy networks still running it, and Open is for networks with no password, which still benefit from a code because guests do not have to hunt for the right name among the neighbours' networks.

Two things break WiFi codes more than anything else: a typo in the SSID and a hidden network that is not marked as hidden. The SSID must match the router's exactly, including capitals and spaces. If the network is hidden, phones need the flag to know they should probe for it rather than wait for it to appear. Test the code from a device that has never joined the network before, because one that already knows the password will connect regardless.

• WPA / WPA2 / WPA3 → nearly all current networks
• WEP → old routers only
• Open → no password; the code still saves guests picking the right SSID
• Hidden network → tick the box or phones will not find it

Printing it: size, contrast and where to put it

Download the code as PNG for a quick print or as SVG if it is going into a designed sign, a menu or a framed card, because SVG stays sharp at any size. Keep the default black-on-white — coloured or low-contrast codes fail on older phone cameras — and leave the white margin around the code untouched; that quiet zone is part of what scanners look for.

Print it larger than feels necessary. A code four or five centimetres across scans from arm's length; smaller ones need the phone almost touching the paper. Cafés and holiday rentals tend to put one on the counter and one in each room; offices put them in meeting rooms for visitors. Since the password is literally in the code, treat the print like the password itself and keep it where only guests you would tell anyway can see it.

Your password is never sent anywhere

Every step runs inside your browser, using the WebAssembly and Canvas APIs your device already ships with. No file is uploaded, no copy is kept, and nothing sits in a queue on a server waiting to be deleted — which is also why the tool keeps working with the network disconnected.

That sentence carries extra weight on this page, because the input is a WiFi password. Many QR generators build the code on their server, which means the network credentials pass through a third party and may be logged. Here the WIFI: string is assembled and drawn as a QR entirely in your browser; the page would produce the same code with the network cable pulled out.

Because the credentials are encoded directly in the image — there is no shortlink, no redirect and no hosted page — the code keeps working forever. If you change the password, generate a new one; the old code simply stops connecting.
