What is PDF metadata?
Every PDF file contains hidden fields that store information about the document — title, author, subject, keywords, producer (the software that created it), and creator. This information is visible in PDF viewers under File Properties and is also read by search engines and document management systems.
Why edit metadata?
- Correct the author name before sending a document officially.
- Add keywords to make the PDF discoverable in document search systems.
- Strip personal information by clearing the author and creator fields.
- Fix the title shown in browser tabs when the PDF is opened online.
