PDF Metadata Tool
Drop in a PDF to reveal the hidden document properties — title, author, the software that created it, and creation/modification timestamps — then download a cleaned copy with that metadata removed. Parsed locally; the file is never uploaded.
Parsed locally in your browser — never uploaded.
What PDF metadata reveals
PDFs commonly embed the author’s name, the application and version that produced them, and precise creation and modification timestamps. For investigators that is a useful provenance signal; for anyone sharing a document it can be an accidental leak. This tool surfaces those fields and lets you strip them before sharing.
Frequently asked questions
What metadata does a PDF contain?
Typically a title, author, subject, keywords, the creating and producing software, and creation/modification dates. Some of these can identify the document’s origin or author.
How do I remove metadata from a PDF?
Load the file and click “Download cleaned PDF”. The tool clears the document-info fields and dates, then saves a new copy you can share.
Is the PDF uploaded to a server?
No. It is read and rewritten entirely in your browser using the open-source pdf-lib library.
Does this remove everything, including hidden text or tracking?
It clears standard document metadata. It does not redact page content, remove embedded objects, or alter XMP streams in every case — for high-stakes redaction use a dedicated tool and verify the result.
