What Hidden Information Is Stored in a PDF?
Document Info Dictionaries store Title, Author, Subject, Keywords, Creator (application name), and Producer (PDF generation library).
Many applications also embed XML Metadata (XMP) catalogs that track document revision history, original file paths on your hard drive, and device serial fingerprints.
When Should You Remove Metadata?
Submitting anonymous peer reviews, job applications, or blind proposals.
Sharing legal filings or investigative research where author identities must remain confidential.
Publishing corporate whitepapers or press releases to prevent leaking internal author identities or draft timelines.
How Local Stripping Works
PDFSimplify reads the PDF dictionary and catalog streams directly in your browser. It clears standard info strings and deletes root XMP metadata streams without changing a single character of visible document text.
Summary
Sanitizing document metadata takes only seconds and prevents unintentional leakage of personal and organizational information.
