Wi-Fi QR code
A code that joins a network. The password never leaves this page.
It runs entirely in this browser tab: the addresses, names and passwords you type are never uploaded, and the tool makes no network request while it works. Open your browser's network panel and try it — nothing leaves the page.
Settings
- Password
- Stays on this device. It is drawn into the code and never sent anywhere.
- Security
- What the network uses. WEP is broken and is here only because old equipment still asks for it. Choices: WPA/WPA2, WEP, Open.
- Hidden network
- A network that does not announce its name. Several phones will not join one from a code.
- Error correction
- How much of the code can be lost and still read. More correction makes a bigger code. Choices: Low, about 7 %, Medium, about 15 %, High, about 25 %, Highest, about 30 %.
- Written as
- A command for a terminal, a request block, or code for a browser. Choices: As a picture, The blocks, As the text behind it.
How to use it
- Paste your text into the box above, or open a file.
- Adjust the settings beside it until the result is what you wanted.
- Copy the result, or save it as a file. The result updates as you type.
Questions
- Does this look anything up?
- No, and that is the point of the group. Nothing here resolves a name, queries a registry or opens a connection. Three tools would want a table bigger than the whole application — the vendor prefixes, the routing table, the full port register — and each of them takes the table from you and says so rather than answering "unknown" about something that exists.
- Why does the subnet calculator show the bits?
- Because a prefix stops being a mystery the moment you see it written out. It is also where the two lengths everybody gets wrong become obvious: a /31 is a point-to-point link with two usable addresses and no broadcast, and a /32 is one host rather than minus one.
- Can I paste something confidential in?
- Yes, and that is why the group is built this way. An internal addressing plan, a DKIM private key's public half, a Wi-Fi password and an authorisation header are all things you would think twice about typing into a website. None of them is sent anywhere, and the request builder hides credentials by default so that what you paste into a ticket is safe to.
- Is what I type uploaded anywhere?
- No. This page carries the whole tool as WebAssembly and runs it on your own device. You can watch your browser's network panel while you use one.
