Redaction only hides visible text and images. PDFs can contain hidden data like author names, creation dates, or even previous versions of text. Sanitizing the PDF removes this hidden information, ensuring that no sensitive details remain in the file. This is crucial for full privacy and security, especially when sharing documents publicly or with external parties.

Yes, Adobe Acrobat Pro has a feature for automatic redaction based on patterns. For bulk personal information like Social Security Numbers or account numbers, you can use pattern-based auto-redaction. This helps find and mark all instances quickly. After the automatic process, it is a good practice to have another person check a random sample to ensure accuracy and completeness.
Redaction codes are labels you can apply to redacted areas, explaining why content was hidden (e.g., 'Proprietary', 'PII'). Using a consistent list of reason codes across your team helps everyone understand why specific information was redacted. This improves clarity and compliance, especially in legal or regulatory contexts, providing a clear audit trail for hidden data.
