FAQ

about this task
  1. First, mark the content you want to hide and click 'Apply'. This darkens the areas.
  2. Next, save the document. Redaction is permanent once the file is saved.
  3. Finally, use the 'Sanitize' option to remove any hidden data like metadata or revision history that might still contain sensitive information. This ensures complete removal.

Redacting content permanently removes the selected text or image from the PDF, making it unrecoverable. It's like cutting out a piece of paper. Drawing a black rectangle only covers the content visually; the original text or image remains underneath and can often be copied and pasted, revealing the sensitive data. Redaction is secure; a black rectangle is not.

For large documents with many instances of specific patterns like Social Security Numbers or account numbers, use Acrobat Pro's pattern-based auto-redaction feature. This allows the software to find and mark all occurrences automatically. After auto-redaction, it is important to have a second person review a random sample to ensure accuracy.

It is important to sanitize a PDF after redacting because redaction only removes visible content. Hidden data, such as metadata, layers, or revision history, can still contain sensitive information. Sanitizing the PDF strips away all this hidden data, ensuring that no confidential details are left behind even in non-visible parts of the file.

Redaction codes are labels you can apply to redacted areas to explain why certain information was removed, without revealing the information itself. For example, a code could be '[PRIVILEGED]' or '[PII]'. To use them effectively, create a consistent list of reason-codes with your team. This helps maintain clarity and legal compliance across multiple documents and users, making it clear why specific data was hidden.
