Adobe InDesign allows users to export files in several formats. The PDF, or Portable Document Format, is used when you want to send a file to someone who does not have InDesign. PDF files can be opened with Adobe Acrobat Reader and many other third party PDF readers. InDesign comes with several preset PDF export options but also allows the user to customize the settings. If the PDF will be printed, either on a desktop printer or a a professional offset press, higher quality settings should be selected. If you will only view the PDF on-screen, select lower quality settings to keep the file size smaller.
