Click Save to save your custom action.
Run the new action by selecting it in Action Wizard and adding all PDFs you want to process.
Review the results and confirm the redactions are applied as expected.
Best practiceAfter batch redaction, always inspect a sample of output files to ensure no sensitive information remains, as recommended by best-practice guides.
Save the redacted PDFs to a secure location.
CautionRedaction is permanent; always work on copies, not originals.
You can automate redactions across many PDFs by building a custom Action in the Action Wizard with your search terms.
This runs in the Acrobat app - there is no separate API for this task.
Redaction in Acrobat Pro works by removing the selected content layer entirely from the PDF. It doesn't just cover it up. When you save the document after applying redaction, that part of the file is deleted. This is why it's permanent and cannot be undone once saved.
Redaction only removes visible text and images. However, PDFs can hold hidden data like metadata (author, date created), layers, or revision history. This hidden data might still contain sensitive information. Sanitizing the PDF removes all this hidden data, making sure no private details are left behind. Always sanitize after redacting to ensure full privacy.
For many Social Security Numbers or other patterns like account numbers, use Acrobat Pro's pattern-based auto-redaction. This feature can find and mark all instances of a specific pattern automatically. After it's done, have another person check a few random samples to ensure everything was redacted correctly.
No, you cannot get back content that you have redacted and saved. Redaction permanently removes the content from the PDF file. This is why it is very important to always work on a copy of your document and keep the original safe.
