About this tool
Create a scannable WiFi QR code so guests can join your network instantly. Generated locally, nothing is uploaded.
A WiFi QR code generator encodes your network name, security type and password into the standard WIFI:T:WPA;S:<ssid>;P:<password>;; payload that phone cameras recognise as a join-network request. Enter the SSID, pick WPA/WPA2/WPA3, WEP or open, and you get a scannable code you can download as a 256-pixel PNG or send to a printer as a table card. The code is drawn in the browser, so the password is never transmitted to build it.
Open WiFi QR Code Generator on AltFTool — it loads instantly in your browser.
Paste your code or data sample into the workspace.
Pick the format, conversion, or analysis you need.
Copy the polished result straight back into your project.
Backslashes, semicolons, commas, colons and quotes in the SSID or password are escaped so the payload does not break mid-scan.
A separate print layout renders the code with your own heading, the network name and a scan hint, sized for a table tent.
Choose WPA, WEP or no password, and flag the network as hidden so the join still works when the SSID is not broadcast.
Open the normal camera app and point it at the code — iOS 11 and later and Android 10 and later both recognise the WIFI: payload and offer a Join Network prompt. Older Androids may need a QR scanner app or the WiFi settings screen, which on Android 10+ has its own scan option under Add network.
WPA and WPA2 personal keys must be between 8 and 63 characters, so anything under 8 will not be accepted by the router even though the code will still encode it. The warning only appears for WPA — WEP and open networks have different rules.
No. The payload string and the QR image are built in the page and the downloaded PNG is produced from the on-page canvas, so the password never leaves the device. Do keep in mind that the printed code itself contains the password in plain form — anyone who scans it can read it.
Usually yes. The code uses error-correction level M, which tolerates roughly 15% of the symbol being damaged or obscured, and it is rendered with a quiet-zone margin. As a practical floor, print it at least 2 cm across and keep the white border intact; longer passwords make a denser code that needs more size.
