about this task

Use the 'Redact text and images' tool in Acrobat Pro.
Drag over the text or image you want to hide.
Click 'Apply' and make sure to turn on the 'sanitize' option.
Save your document. This makes the redaction permanent and removes hidden data.

Sanitizing a PDF after redaction is important because redaction only hides visible content. Hidden data, like metadata, comments, or previous versions, might still contain sensitive information. Sanitizing removes all this hidden data, ensuring that no sensitive details are accidentally left in the file after you redact it. This makes your document truly secure.

For many social security numbers or other personal information, use Acrobat Pro's pattern-based auto-redaction. This feature can find and redact all matching patterns automatically. After it's done, have a teammate check a few random examples to make sure it worked correctly.

Method	Effect	Security

Using the Redact tool	Permanently removes content	Text is completely deleted and cannot be recovered or copied.

You should always work on a copy because redaction is a permanent change. Once you save a redacted document, the original sensitive information is gone forever. If you make a mistake or need the unredacted version later, having a copy ensures you still have the original file with all its content.
