Questions
Does cleanup remove confidential text on a page?
No. Cleaning document extras is different from redacting visible content. Names, numbers and pictures on the page can remain. Use Redact PDF for information that must not be readable in the result.
Is a cleaned file guaranteed safe?
No tool can make that blanket promise for every PDF. This tool removes the supported categories you select; it is not a malware scanner or a complete security review of the document.
Which saved document details can I remove?
Choose saved Title, Author, Subject, Keywords, Created with, PDF software, Date created and Date modified properties to remove.
Can I remove extra properties added by other software?
Remove extra properties added by the creating application.
