This runs in the Acrobat app - there is no separate API for this task.
Redaction permanently removes the text or image. It is gone from the file. Drawing a black rectangle only covers the text. The text is still underneath the rectangle and can be copied or searched. Redaction is safe; a black rectangle is not safe for private data.
Redaction removes only what you see. PDFs can have hidden data like metadata, layers, or old versions. Sanitize removes these hidden parts. This makes sure no sensitive information is left in the file, even if it's not visible on the page.
For many common types of private data, like Social Security Numbers or account numbers, Acrobat Pro has an auto-redaction tool. It can find patterns and mark them for you. After it runs, you should still have someone check a few random examples to be sure it worked correctly.
