Protected document builder

Pick a file and a password; this page produces a single self-contained HTML file that decrypts and downloads it. Everything runs in your browser - nothing you enter is ever uploaded.

File

The document to encrypt. One file per output.

File to protect

Password

Used only in your browser to derive the encryption key. Never stored, never transmitted. There is no way to recover it, so keep a copy somewhere safe.

Learn more button: always included in every output and cannot be turned off. The visit destination is fixed by this builder and cannot be overridden (see below).

Custom CSS

Optional extra stylesheet, inlined into the output after the built-in theme so it can override it. External requests are stripped so the file stays self-contained and works offline.
