FAQ
What hidden data can a PDF contain?
Usually a title, an author, the software that made it and the dates it was created and modified; sometimes also attachments, scripts, author names on comments, data typed into forms and hidden layers. None of it shows on the pages, but anyone who receives the file can look it up.
How is this different from “Edit PDF metadata”?
“Edit PDF metadata” changes the title, author, subject and keywords. This tool finds the hidden data in a file, which also includes attachments, scripts and hidden layers, and removes what you choose.
