Optional. Enable any of these values by adding it to the profile and setting it equal to ON.
| discard-comments-forms-multimedia | Removes changes added to the PDF document, such as comments from a reviewer or completed forms fields. | |
| discard-document-information-and-metadata | Removes document descriptions and metadata | |
| discard-file-attachments | Removes files attached to the document | |
| discard-external-crossreferences | Removes references to external data. This would include links to external resources, like a photograph or another PDF document that could be downloaded from a web page or FTP site. This option effectively removes the hyperlinks to these items. | |
| discard-private-data | Removes piece data relevant to the application that created the file. Some applications, like Adobe Illustrator, add their own unique values to a PDF document when generating that document. These values are useful to the original software product if the PDF is opened and edited in that product again. But these values can also be removed. |
