About this tool
Every PDF carries hidden metadata - title, author, subject, and keywords - that doesn't show up on the page but is stored in the file itself and can appear in search results, file properties, and document management systems. This tool lets you view and edit that metadata directly, useful for correcting an author name, adding proper keywords for organization, or cleaning up sensitive information before sharing a file.

Which PDF metadata to set before sharing
The title appears in the browser tab when a PDF opens online and is often shown in search results, so set it to the real document name rather than a file name like "Document1". Set the author to your name or company.
Before sending a PDF outside your organisation, check the author and keywords for anything you did not mean to share - an old template author, an internal project code or a colleague’s name.

Frequently asked questions
No - metadata is separate from the page content. Editing the title, author, subject, or keywords doesn't alter anything on the pages themselves.
Common reasons: correcting an inaccurate author/title before publishing, adding keywords to help the file surface in searches, or removing metadata that reveals more than you intended (like the original file path or software used).
Yes - the Metadata Viewer tool shows all of a PDF's current metadata without changing anything, if you just want to inspect it first.
Yes. When a PDF is published online, search engines often use its Title field as the result headline. A descriptive title instead of 'Document1' or 'untitled' makes the result far more clickable.
Author names, internal project codes and old titles left over from a template. Check the creator and producer fields too, which can reveal the software and sometimes the organisation that made the file.
Document management systems, desktop search and some digital libraries index them, so consistent keywords make files easier to find in large archives.
