How do I make sure my redactions are truly permanent in Acrobat Pro?

Use the 'Redact' tool, not just a black rectangle. After applying redactions, run the 'Sanitize' feature to remove all hidden information. Save the document, then try to search for or copy-paste the redacted text to verify it's gone.

Redacting content with the 'Redact' tool in Acrobat Pro permanently removes the selected text or image data from the PDF. It's truly gone. Drawing a black box, however, only covers the content visually; the original text or image data remains underneath and can often be copied and pasted, making it still visible to others. Always use the dedicated redaction tool for security.

Redaction only removes visible content. A PDF can also contain hidden data like metadata, comments, or revision history. Sanitzing the PDF removes all this hidden information, ensuring that no sensitive details are accidentally left behind after you've redacted the visible parts. This provides a complete cleanup.

For large documents with many instances of sensitive information like SSNs or account numbers, use Acrobat Pro's pattern-based auto-redaction feature. This allows the tool to find and mark all occurrences of a specific pattern. After auto-redaction, it's a good practice to have a colleague review a random sample of the document to ensure all sensitive data was correctly removed and nothing was missed.
