What is PDF metadata?

Besides its pages, every PDF can carry descriptive information: a title, an author, a subject, keywords, the application that created it, the program that produced the PDF and the dates it was created and last modified. This metadata is what readers show in the window title and the document properties, what search engines display for PDFs published on the web, and what document management systems use to index files.

Why edit or remove it?

  • Professional presentation: a report whose title reads “Microsoft Word – draft_v7_final2.docx” does not look finished. Set a proper title before you send it.
  • Search and archiving: accurate titles, subjects and keywords help you and others find documents later, both on your computer and on the web.
  • Privacy: metadata can reveal the author's full name, the company, the software used and when the file was edited. Before publishing a document or sending it outside your organisation, you may prefer to remove all of it.

Edited in your browser

The information is read and rewritten by the open-source pdf-lib library on your own device. The document is not uploaded, which matters precisely when you are cleaning metadata for privacy reasons.

How to use it

  1. Drop your PDF onto the drop zone or click Choose file. The current values appear in the form, together with the creation and modification dates.
  2. Edit any field. Leave a field empty to delete it. Separate keywords with commas.
  3. Click Save metadata to apply your changes, or Remove all metadata to strip every field at once.
  4. Download the new file. The page content is copied unchanged.

Technical notes

PDF metadata lives in two places: the classic document information dictionary and, in many files, an XMP metadata stream. Some readers prefer one, some the other, so leaving an outdated XMP stream behind could make your changes seem to disappear. This tool therefore writes the information dictionary and removes the XMP stream. When you save changes, the modification date is set to the current time.

Frequently asked questions

Does removing metadata make a document anonymous?

It removes the descriptive fields, but names can also appear in the visible text, in comments or in images. Review the content as well before publishing sensitive documents.

Can I edit protected PDFs?

Encrypted files must be unlocked first with Unlock PDF, using their password.
