Why your PDF says it was made in Word 2013 — and how to change it

A Portable Document Format (PDF) is a common file format to share documents and ensure consistency among devices. When you create a PDF, softwares that are used to create it may embed several information regarding the PDF creation information. In this article, we will explore more regarding these metadata hidden in your PDFs.

Common Metadata in PDFs

PDFs are commonly shipped with an info dictionary that contains the following data:

  • Title: Title of te document
  • Author: Writer of the content of the document
  • Subject: Short summary of the content
  • Keywords: List of searchable words regarding the content
  • Creator: Software used to create the content (ex: Word)
  • Producer: Software used to create the PDF (ex: LibreOffice)
  • Creation Date: A date stating the time of PDF creation
  • Modification Date: A date stating the latest modification of the PDF

Hence, that is why we can conclude that a document has been made using a specific software by looking at its info. It is also important to note that in addition to this info, PDF may also embed another metadata in the XMP format.

What is the Purpose of these Info?

These info dictionary are filled for numerous reasons. Mainly, these include:

  • Indexing: Help systems find relevant documents during search
