Pigpen cipher
Each letter drawn as the walls of the box it sits in, as a picture you can print or trace.
It runs entirely in this browser tab: the text you paste is 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. There is no sign-up and no limit beyond what your own browser can hold.

Questions
- Is my text uploaded anywhere?
- No. This page carries the whole tool as WebAssembly and runs it on your own device. Nothing you paste is sent anywhere.
- Is this secure?
- No. Every cipher on this site is a puzzle cipher, and the tool says so on each result. They are for escape rooms, cryptograms, coursework and historical curiosity.
- Can I get this result again later?
- The settings travel in the page's address, after the #, so a link reproduces them exactly — key included — and the fragment of an address is never sent to a server. Your last settings are also remembered on this device, which is worth knowing before you type a key you care about.
- Is there a version that is not a web page?
- Yes. The same ciphers are built as a desktop application from the same code, with a save dialog instead of a download and no network code at all.
