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 in Acrobat Pro permanently removes the selected text or image from the PDF. It is gone forever. Drawing a black rectangle only covers the content visually. The text is still underneath and can be found by selecting all text, copying it, and pasting it into another document. This means the sensitive information is still there and not truly hidden.
For many items like social security numbers or account numbers, use the pattern-based auto-redaction feature in Acrobat Pro. This tool can find and redact all instances of a specific pattern automatically. After it runs, have another person review a random sample of the redactions to make sure they are correct and complete.
Redacting only removes visible content like text and images. However, PDFs can contain hidden data such as metadata, layers, and revision history. This hidden data might still hold sensitive information. Sanitizing the PDF removes all this hidden data, ensuring that no sensitive details remain in the file. This makes the document truly secure for sharing.
Redaction codes are labels you can add to redacted areas to explain why the content was removed (e.g., 'Privacy', 'Confidential'). They do not reveal the hidden text. Using a consistent list of reason-codes across your team helps everyone understand why certain information was redacted. This is especially useful in legal or compliance situations to maintain clarity and accountability.
