- Product
- Device & OS
- not provided
- Scenario
- Sharing a secure PDF document without revealing sensitive document properties to the recipient.
- Observed behavior
- Password protection prevents editing but still leaves the document's creation date and other metadata visible to anyone who opens the file.
Before modifying or deleting document metadata, create a backup copy of your original PDF in case you need to reference the original creation date or author details later.
Clear Metadata via Document Properties
Remove sensitive information like Author, Subject, and Keywords directly from the PDF properties menu.
While permission passwords restrict editing and printing, they do not encrypt or hide the document's metadata. To prevent recipients from seeing this data, you must manually delete it or use a metadata sanitization tool before distributing the file.
Open your PDF file and navigate to the Document Properties menu, usually found under 'File' > 'Properties' or 'Document Info'.
Go to the 'Description' or 'Custom' tab where the document's metadata is stored.
Manually delete the text in fields such as Author, Title, Subject, and Keywords.
Click 'OK' to apply the changes, then save the document as a new file to ensure the metadata is overwritten.

Frequently Asked Questions
Does adding a password to my PDF hide the creation date?
No. A permissions password restricts actions like editing and printing, but standard document properties (like creation date and author) remain visible to anyone who opens the file.
How can I change the creation date of a PDF?
You cannot directly edit the original creation date field in most standard PDF readers. To generate a new creation date, you can try 'printing' the document to a new PDF file using a virtual PDF printer.
What is PDF metadata?
PDF metadata is hidden information embedded in the file, which can include the author's name, document title, software used to create the file, creation date, and modification date.
Can metadata be recovered after I delete it?
If you properly sanitize or clear the document properties and save the file as a new copy, standard users cannot recover it. However, if the file has previous versions embedded or wasn't sanitized with a dedicated tool, forensic recovery might still be possible.
