What this tool does
PDF Metadata Extractor reads a PDF in your browser and turns the useful document-level signals into a CSV you can keep with an audit, print, legal, or content migration workflow. It reports the PDF version, title, author, subject, keywords, creator, producer, creation date, modification date, linearized flag, encryption hint, and the strongest page-count signal found in the page tree. It is built for the real moment before you upload a file to a government portal, send a contract to a print shop, publish a downloadable report, or compare exported PDFs from different systems. The parser is intentionally local and read-only: it inspects bytes already on your machine and does not attempt to rewrite or decrypt the document.

Real-world use cases
Review contract exports
Confirm author, producer, date, encryption flag, and page count before sending a signed PDF outside the company.
Audit publishing files
Keep a CSV of PDF metadata next to a release checklist so editors can spot wrong titles or stale producer strings.
Common pitfalls
Treating metadata as proof of authorship; it is editable and should be used as a clue.
Assuming an encrypted flag means the file cannot be opened; owner restrictions and user-password encryption differ.
Privacy
PDF bytes are parsed locally. The tool does not upload, rewrite, or store the document.
