How to check and remove PDF metadata

A PDF usually carries your name, your software, and when it was made. Often none of that is meant for the recipient.

PDFs carry a metadata block that most people never see. It typically holds the author's name, the producing application, creation and modification timestamps, and often the original filename and title.

This has embarrassed a lot of organisations. A document sent as anonymous carrying an author's name, or a tender response revealing it was created after the deadline, are both routine occurrences.

Step-by-step

  1. Add your PDF.
  2. Read what it contains.
  3. Strip the fields you do not want to share.
  4. Download the cleaned copy.

What is usually in there

What removing metadata does not do

It cleans the document's properties. It does not touch the content, and it is not a way of hiding information written into the page.

If you covered something with a black rectangle, removing metadata does nothing about it — the text is still underneath. That needs proper redaction, which deletes the content rather than drawing over it.

Before sending anything sensitive

Check the metadata, check for tracked changes if it came from a word processor, and check that anything obscured was actually removed rather than covered. Those three account for the overwhelming majority of accidental disclosures.

Frequently asked questions

Is the PDF uploaded?

No. It is read and rewritten in your browser.

Does this remove text I covered with a rectangle?

No. That text is still in the file underneath the rectangle. Use the redaction tool, which removes the content itself.

Will removing metadata change how the document looks?

No. Metadata is separate from page content, so the document renders identically.
