How do I make sure my redaction is permanent in Acrobat Pro?

First, use the 'Redact text and images' tool and apply the redaction. Second, when prompted, choose to 'sanitize' the document. This removes hidden data that might still contain sensitive information. Third, save the file. Once saved, the redaction is permanent. Finally, open the saved file and try to copy-paste or search for the redacted content to verify it's truly gone.

about this task

First, use the 'Redact text and images' tool and apply the redaction.
Second, when prompted, choose to 'sanitize' the document. This removes hidden data that might still contain sensitive information.
Third, save the file. Once saved, the redaction is permanent.

Drawing a black box is like putting a sticker over text; the text is still underneath and can be easily copied and pasted. The Redact tool, however, permanently removes the selected content from the document. It replaces the text or image with a black bar. This means the original information is truly gone and cannot be recovered. Always use the Redact tool for sensitive information.

Sanitizing a PDF after redaction is crucial because redaction only removes visible content. PDFs can contain hidden data like metadata (author, creation date), comments, attachments, or even previous versions in the revision history. This hidden data might still hold the personal details you wanted to remove. Sanitizing ensures all such hidden information is stripped away, making the document truly clean.

No, you cannot automate redaction using an API like the Adobe PDF Services API. The redaction feature is only available in the desktop version of Acrobat Pro. This means you must manually perform redaction on each document using the desktop software.

Redaction codes are labels you can apply to redacted areas to explain why the information was removed, without revealing the information itself. For example, you might use codes like 'PII' (Personally Identifiable Information) or 'Confidential'. You can edit or create your own code sets in Acrobat Pro. Using consistent codes helps teams understand the reason for redaction and maintains compliance, especially in legal or government contexts.
