How do I use Acrobat Pro to redact sensitive information from a PDF?

Open the PDF in Acrobat Pro. Go to All tools and pick 'Redact a PDF'. Drag over the words or images you want to hide. Click 'Apply' and turn on 'Sanitize'. Save the file and check if the information is gone.

What is the difference between drawing a black box and using Redact in Acrobat?

Black Box Redact. Covers text but does not remove it Removes text completely People can still copy and see the words Words are gone and cannot be copied Not safe for private info Safe for hiding private info

If my PDF scan is blurry, can Acrobat Pro still redact the information?

If the scan is just an image, Acrobat cannot find text to redact automatically. You can still draw over the area to redact, but you must be careful to cover all private parts. Always check the result by trying to copy or search for the words.

What should I do to make sure my redaction in Acrobat Pro worked and is safe?

After redacting, try to search for the private words in the PDF. Copy and paste from the redacted area to see if anything is revealed. Run the 'Sanitize' tool to remove hidden data. Ask a teammate to check the file too, if possible. Always keep the original unredacted file safe and controlled.

Sanitizing a PDF after redacting is important because it removes hidden information that is not visible on the page. This includes metadata, old document versions, and other data that may still contain private details. Without sanitizing, someone could find this hidden information even if the visible text is gone, so always use this step to keep your document truly private.
