Across past audits, what types of payroll data or metadata tend to leak when files are shared — embedded spreadsheets,…
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.
Redacting with Acrobat's tool permanently removes the content, making it unrecoverable. Drawing a black rectangle only covers the content; the original text or image is still underneath and can be copied or searched for. Always use the specific redaction tool for security.
No, redacting only removes visible text and images. Hidden data like metadata, comments, or revision history are not removed by redaction alone. After redacting, you must use the 'Sanitize' option, which Acrobat usually offers after you apply redaction, to strip out all hidden information and ensure full privacy. Always verify both visible and hidden content.
It is important to use a copy because redaction is permanent. Once you save a redacted document, the original sensitive information is gone forever. Working on a copy means you always keep the unredacted original document safe, in case you need it later.
For many SSNs or account numbers, Acrobat Pro has a feature for 'pattern-based auto-redaction'. This lets you search for specific number patterns and redact all matches at once. After auto-redacting, it's a good idea to have a second person check a few random pages to make sure everything was hidden correctly.
