Across projects, when I release drawings to trades I repeatedly misjudge what stays restricted versus what the field n…
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.
Redaction permanently removes the text or image data from the PDF file. It's like cutting out a piece of paper. Drawing a black box only covers the text visually; the text is still part of the file and can be easily copied and pasted to reveal it. Redaction is secure; a black box is not.
Sanitizing a PDF is important because redaction only removes visible content. A PDF can have hidden data like author names, creation dates, comments, or even old versions of text. Sanitize removes all this hidden information, making sure no secret data is accidentally left behind after you redact the visible parts.
For many SSNs or account numbers, use Acrobat's pattern-based auto-redaction. This feature can find and mark all instances of specific number patterns automatically. After the auto-redaction, have another person review a random sample of the redacted areas. This helps catch any mistakes and ensures all sensitive data is properly hidden, especially in large documents.
Redaction code sets are labels you can add to redacted areas to explain why something was removed. For example, you might use 'Privacy' or 'Confidential'. Using consistent code sets across your team helps everyone understand why certain information was hidden. It also makes it easier to manage and audit documents that have been redacted.
