## How to redact a PDF with Arthize

Real redaction deletes the underlying content; a black rectangle alone can be removed to reveal the text.

Copying text from under a fake redaction box exposes the hidden data — a common leak.

Redaction should also clear document metadata that can leak names and edit history.
