What are the best practices to follow when redacting documents for legal or public release?

Always work on a copy of the original document to avoid accidental loss. Use a consistent list of reason-codes for redactions across your team. After redacting, run the Sanitize tool to remove all metadata. Verify the redaction by trying to search for and copy-paste the redacted terms. For large amounts of personal data, use pattern-based auto-redaction and have a peer review a sample.

about this task

Drawing a black rectangle only covers the text, leaving it still present underneath and easily recoverable. Acrobat Redact, however, permanently removes the selected content from the document. This means the information is gone and cannot be copied or searched for after the redaction is applied and saved.

Redaction only removes visible content from your PDF. Hidden data, such as metadata, layers, and revision history, might still contain sensitive information. Sanitizing the PDF after redaction ensures that all this hidden data is also stripped away, providing full protection for your confidential information before sharing the document.

For large amounts of personal data, use pattern-based auto-redaction and have a peer review a sample.

For redacting many instances of patterned information like Social Security Numbers or account numbers, use Acrobat's pattern-based auto-redaction feature. This allows the software to find and mark all occurrences automatically. After the auto-redaction, it is a good practice to have a colleague do a quality check on a random sample to ensure accuracy.
