Redact
Box off the parts that should not leave the office. On export, those pages are re-rendered to an image, so the text underneath is gone from the file, not just hidden under a black bar.

Confirm first that the file really holds something that must not get out. Redaction cannot be undone.

Know the trade-off before you start. The only way to make covered text truly unextractable is to redraw the page as an image. A redacted page can no longer be searched, its text can't be selected, and it softens a little when printed at high zoom. Many online tools only lay a black box on top; the original text stays underneath and can still be copied out. That isn't redaction, it's a sticker, and this tool doesn't do it.
