We are publishing a public tender tomorrow and I need to decide which redactions remain to balance transparency with c…
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 permanently removes the information, making it unrecoverable. Drawing a black box only covers the text visually. Someone can still select and copy the text underneath the box, revealing the sensitive content. Always use the dedicated 'Redact' tool for true data removal.
Yes, Acrobat Pro has a feature for pattern-based auto-redaction. This means it can automatically find and mark common patterns like Social Security Numbers or account numbers throughout your document. After the automatic redaction, you should still have a person check a random sample to ensure accuracy and completeness.
Sanitizing a PDF is important because redaction only removes visible content. Hidden data, such as metadata, layers, or revision history, might still contain sensitive information. Sanitizing removes this hidden data, ensuring that all confidential information is gone and cannot be recovered by others.
No, you cannot automate redaction using the Adobe PDF Services API. The redaction feature is specifically designed for the desktop version of Acrobat Pro. There is no API operation available for redaction at this time.
