About: PDF Metadata → JSON

Extract metadata from a PDF (Info dictionary + XMP) in JSON: title, author, dates, producer software, keywords… for auditing, compliance, and automation.

Use Cases

  • Compliance Audit / GDPRDetect sensitive information in the metadata (author, internal software, paths, company).
  • Generation DebuggingIdentify which tool produced the PDF (Producer/Creator) and when it was generated.
  • Indexing & CatalogingRetrieve title, subject, keywords, and other fields to feed a document management system or an internal engine.
  • Version comparisonCompare two PDFs and spot changes in dates, authors, or XMP.

What You Get

A complete JSON of standard metadata (Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate…).

The export of XMP blocks when they exist (often richer and more structured than the Info dictionary).

Limits and points of attention

  • Metadata can be empty, inconsistent, or deliberately falsified: it is not proof of origin.
  • Date formats may vary (timezone, PDF format): interpret them carefully.
  • For encrypted PDFs, access to metadata may be restricted.

Frequently asked questions

What is the difference between Creator and Producer?
Creator is often the application that created the content; Producer is the tool that generated/transformed the PDF.
Why do I not have XMP?
Not all PDFs contain it. Many are limited to classic Info fields.
Does the tool modify the metadata?
No, it reads and exports. To remove metadata, use a cleaning/sanitization tool.

Tip

If you publish a PDF online, always check the metadata before distribution: it is a common place for information leaks (author, company, internal tools).
