Open one of your PDFs in Adobe Acrobat Pro.
Best practiceMake sure you are using Adobe Acrobat Pro DC or later, as some features are not available in Standard.
Go to the 'Tools' pane and select 'Redact'.
Best practiceYou can also find 'Redact' in the right-hand pane or by searching in the Tools search bar.
Click 'Mark for Redaction' > 'Text & Images', then use your mouse to draw a redaction box over the area you want to redact.
CautionDo not apply the redaction yet; just mark the area.
Right-click the redaction mark and select 'Repeat Mark Across Pages...'.
Best practiceThis feature lets you apply the same redaction area to a range of pages within the current PDF.
In the dialog, specify the page range and click 'OK' to mark the same area on all selected pages.
Best practiceReview the marks to ensure they align correctly on each page.
To redact recurring text, click 'Find Text & Redact', enter your search term, and use 'Find Next' or 'Find All' to mark all instances.
Best practiceYou can use 'Match case' or 'Whole words only' to refine your search.
To apply these redactions across multiple PDFs, go to 'Tools' > 'Action Wizard', create a new Action, add the 'Redact' step, and configure it to use your search or redaction marks.
Best practiceYou can add multiple files to the Action and run the redaction process in batch.
Click 'Apply Redactions' to permanently remove the marked content, then save your files.
CautionRedactions are permanent and cannot be undone after saving.
For consistent redaction across multiple PDFs, carefully match the area coordinates and dimensions in each file before applying redactions.
This runs in the Acrobat app - there is no separate API for this task.
Drawing a simple black box over text in a PDF only covers it visually; the text remains underneath and can be easily copied and revealed. Acrobat's Redact tool, however, permanently removes the selected content, making it unrecoverable. This is crucial for true security, ensuring sensitive information cannot be accessed by anyone.
Sanitizing a PDF after redaction is important because redaction only removes visible text and images. Hidden data, such as metadata (author, date created), comments, attachments, or previous versions, can still contain sensitive information. Sanitizing removes all this hidden data, ensuring that no confidential details are accidentally left in the document, making it truly secure for sharing.
Redaction codes are labels you can apply to redacted areas, explaining why the content was removed (e.g., 'Privacy', 'Confidential', 'PII'). Using a consistent list of reason-codes across your team helps everyone understand why specific information was hidden. This improves clarity, consistency, and compliance, especially when many people are working on the same types of documents.
Yes, for large amounts of personal data like Social Security Numbers (SSNs) or account numbers, Acrobat Pro offers pattern-based auto-redaction. This feature can automatically find and mark all instances of specific patterns within your document. After running the auto-redaction, it's a good practice to have a second person (peer-QC) review a random sample of the redactions to ensure accuracy and prevent any mistakes.
