What is PDF metadata?

PDF metadata is a set of document properties stored in the PDF file itself, separate from the page content. It includes fields like Title, Author, Subject, and Keywords that describe the document. Search engines, document management systems, and accessibility tools use this metadata to index and categorise PDFs.

Fields explained

  • Title — The document's display name (different from the filename)
  • Author — The person or organisation that authored the content
  • Subject — A brief description of the document's subject
  • Keywords — Comma-separated terms for search and indexing
  • Creator — The application used to create the original document
  • Producer — The PDF conversion tool or library

SEO and accessibility benefits

Properly filling in PDF metadata helps search engines index your documents more accurately and improves accessibility for screen readers. Adding a descriptive Title and Author is especially important for PDFs published on the web or distributed through document management platforms.
