FAQ
What is PDF metadata?
Metadata is information stored inside the PDF, such as title, author, subject, keywords, producer/creator, and creation or modification dates.
Does removing metadata change the PDF content?
No. The visible pages stay the same. Only document information fields are updated or removed.
Can I make a PDF anonymous?
Yes. Enable the anonymous option to clear common metadata fields and remove identifying information.
Will this remove hidden text or comments?
This tool edits document metadata fields. If you need to permanently remove sensitive content on pages, use Redact.
Why do timestamps still appear in some PDFs?
Some viewers show additional internal fields or embedded XMP metadata. If your PDF has extra metadata layers, results may vary depending on how the file was created.
What should I do after editing metadata?
Common next steps are Protect (password), Flatten (compatibility), or Redact (remove sensitive page content).
