We keep having to redact records for external reviews and every time someone does it differently, risking exposure or …
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.
Redaction permanently removes the selected content from the PDF, making it unrecoverable. Drawing a black rectangle only covers the text, but the text itself remains in the document and can still be copied, searched, or revealed. Always use the dedicated Redaction tool for security.
Redacting sensitive content is crucial for protecting privacy and complying with legal requirements. It prevents unauthorized access to personal information, financial details, or confidential company data when documents are shared publicly or with specific parties. This helps avoid legal issues and maintain trust.
For large documents with many instances of sensitive patterns like SSNs or account numbers, use Acrobat Pro's pattern-based auto-redaction feature. This tool can automatically find and mark all matching patterns for redaction. After using it, have another person review a random sample of the document to ensure all necessary redactions were correctly applied.
No, true redaction that permanently removes content is a feature exclusive to Adobe Acrobat Pro desktop software. There is no redaction operation available through the Adobe PDF Services API, nor is it reliably offered by online PDF tools. Always use Acrobat Pro for secure redaction.
