What fields can I modify in a PDF?

You can view and modify standard properties like Title, Author, Subject, Keywords, Creator (the tool that created the PDF), and Producer (the PDF engine used).

What is Safe Scrub mode?

Safe Scrub is an anonymization feature that removes all trace metadata, creation dates, modification dates, software footprints, and unique document IDs in a single click.

Can I compare metadata between two files?

Yes, our metadata workspace includes a side-by-side comparison panel to verify edits before saving or compare two different documents.

How do I download the edited PDF?
