Redaction is a permanent action that completely removes the underlying text or image data from the PDF. It makes the content unrecoverable. Drawing a black rectangle, however, only covers the content visually. The text or image data still exists underneath and can often be copied, pasted, or recovered by others. Always use the Redaction tool for sensitive information.

Redaction only removes visible content. A PDF can still contain hidden data like metadata (author, creation date), comments, attachments, or previous versions. Sanitizing the PDF removes all this hidden information, ensuring that no sensitive data remains in the document, even if it's not visible on the page.

For many items like Social Security Numbers or account numbers, Adobe Acrobat Pro offers a pattern-based auto-redaction feature. You can search for specific patterns (like 'XXX-XX-XXXX' for SSNs) and redact all matches at once. After auto-redaction, it is a good practice to have another person check a few random pages to ensure accuracy.
