What is this tool?

PDF Metadata Editor reads the document information embedded in a PDF — title, author, subject and keywords — and lets you edit it, then writes the changes back into a new file using pdf-lib. Everything happens locally in your browser, so the file is never uploaded anywhere.

Common uses

  • Fixing an incorrect or missing title before sharing a document
  • Adding your name as the author of a PDF you created
  • Adding keywords to help a PDF be found in search or a document library
  • Cleaning up metadata left over from the original authoring tool

FAQ

Does this change the visible content of the PDF?

No, only the document metadata is changed — the pages and their content stay exactly the same.

How do I enter multiple keywords?

Separate them with commas, for example: invoice, 2026, finance.

Is my PDF uploaded to a server?

No, everything is read and rewritten entirely in your browser using pdf-lib — your file is never sent anywhere.
