How to Redact Sensitive Information from a PDF
Proper redaction is intended to remove sensitive page content, not merely place a visible shape over it. Always work on a copy and inspect the exported result before distribution.

- 2.Mark every sensitive area that must be removed.
- 3.Export the result, reopen it, and verify that the hidden information cannot be selected or recovered visually.
Why a drawn black rectangle may be unsafe
Some editing tools place a shape above the original text while leaving the underlying text selectable. Use a purpose-built redaction workflow and test the output rather than assuming a dark box is permanent.
Clean metadata as a separate step
Visible redaction does not necessarily remove document properties. After redacting, use Remove PDF Metadata when author or creator information must also be cleared.
