How removing metadata works here

  1. Drop the file. The PDF opens in a worker in your tab.
  2. Choose whether to keep the title. The title is what a reader shows in its tab; everything else goes regardless.
  3. Download. The document properties, the XMP packet, page metadata and application data are removed, the file identifier is replaced, and the result card lists what was found.

What it does

  • Removes the Info dictionary entries, including custom ones.
  • Removes the XMP packet and any per-page packets.
  • Removes PieceInfo, where applications keep private data.
  • Writes a new file identifier, since the old one can derive from the original's dates.

What it does not do

  • It does not remove text, images, comments or form field values from the pages; those are content, not metadata.
  • It does not remove a digital signature.
  • It does not find metadata hidden inside embedded images (a photo's EXIF).

Questions

What metadata does a PDF carry?

A short list of document properties (title, author, subject, keywords, the creating and producing software, two dates), often an XMP packet with the same and more, sometimes private application data and a file identifier.

Is the content changed?

No. Pages, text and images are exactly as they were. Only the entries that describe the file are removed.

Why keep the title?

Readers show it in the tab and in recent files; without it they show the file name. Keep it when the title says nothing you would not want seen.

Does my file leave my computer?

No. Everything runs in your browser tab. The only network requests are the site's own files.
