  • Photos and illustrations: The quality, resolution and format of photos and illustrations in a document have a key impact on its size. High resolution photos can significantly increase file size.
  • Links and annotations: Adding interactive elements such as links or annotations can affect file size.
  • Attachments: If additional documents, files or multimedia are attached to the PDF file, this will significantly affect its size.
  • Form data: Forms filled with data can increase file size, especially if they contain large amounts of information.
