Redaction Pitfalls

Many people “hide” text visually without removing it structurally. That is not safe redaction.

Common mistakes

• Drawing black boxes over text without true redaction.
• Exporting from editable docs without checking final PDF contents.
• Forgetting comments, form fields, and annotation layers.

Safer defaults

• Treat every external share as if it may become public.
• Open the final file and select text in redacted areas to verify removal.
• Use /scrub to remove metadata and interactive structures before sharing.

What this does not protect

• Sensitive content still visible in scans or screenshots.
• Content-derived clues (phrasing, timestamps in body text, unique formatting).
• High-end forensic recovery from source files outside the PDF.
