Looking at requests for personnel files over the last year, what are the recurring types of sensitive information that…
Open Adobe Acrobat Pro.
Go to the Tools view and locate Action Wizard.
Click New Action to create a custom batch process.
Under Choose tools to add, select Redact from the list.
Add the redact action to search for and remove text from your workflow.
Configure the search settings to enter your predefined terms or patterns (such as specific words or regular expressions).
Set the redaction properties as needed (such as redaction mark appearance or overlay text).
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.
Redacting content with the 'Redact' tool permanently removes the information, making it unrecoverable. Drawing a black box is like painting over text; the text is still there underneath and can be copied or searched. True redaction ensures the data is gone forever, which is important for security.
For large documents with many instances of specific patterns like SSNs or account numbers, use Acrobat's pattern-based auto-redaction feature. This allows you to search for and redact all occurrences of a specific pattern at once. After auto-redaction, it is important to have a second person (peer) review a random sample of the document to ensure all sensitive data was correctly removed.
Using a consistent reason-code list helps your team maintain clarity and accountability. It ensures everyone understands why certain information was redacted. This is especially important in legal or compliance settings, where you might need to explain redaction decisions later. It also makes future reviews or audits easier.
No, once you save a document after applying redaction, the changes are permanent. The redacted content is completely removed and cannot be recovered. This is why it is very important to always work on a copy of your original document.
