Why Use the PDF Metadata Viewer
Document Inspection
Quickly check who created a PDF, when it was made, and what software produced it before accepting or distributing it.
Metadata Cleanup
Remove or update sensitive metadata like author names, company info, or creation dates before sharing documents externally.
Privacy Protection
Verify that no hidden personal data is embedded in a PDF before uploading it to public platforms or sending it to clients.
Batch Cataloging
Use the copy-as-JSON feature to export metadata from multiple PDFs for inventory tracking or database entry.
How It Works
PDF files store metadata in a document information dictionary and an XMP metadata stream. This includes standard fields like title, author, and creation date, as well as technical properties such as PDF version, producer software, and encryption status. The tool reads these internal structures and displays them in a human-readable format.
Common Metadata Fields
- Title — The document's title, often displayed in browser tabs or document managers.
- Author — The person or organization that created the document.
- Subject — A brief description of the document's content or purpose.
- Keywords — Searchable terms separated by commas, useful for cataloging and retrieval.
- Creator — The application originally used to create the document (e.g., Microsoft Word, LaTeX).
- Producer — The software that converted the document to PDF format.
Privacy Note
PDF metadata can reveal sensitive information such as author names, company details, software versions, and file paths. Before sharing a PDF publicly, consider stripping or editing metadata to protect your privacy. Use the "Edit Metadata" feature to remove or replace identifying fields before distribution.
