How to do it

  1. Load the PDFEvery field it carries is shown, including the XMP block if present.
  2. Edit or wipeChange title, author, subject or keywords. Or wipe everything at once.
  3. DownloadThe page content does not change.

Why do it in your browser

The author's name, the real creation date or the software used are exactly the kind of data people do not know they are sharing. Checking them here does not mean handing the document to anyone.

Frequently asked questions

What is the XMP block?

A second set of metadata in XML that usually repeats author, title and dates. Wiping removes it too; saving edits removes it so no stale data remains.

Does it delete the page text?

No. Only the hidden file data. The visible content stays the same.

Does it remove comments or annotations?

No; those are not metadata. That is coming as a separate feature.
