Attachments Panel

PDF files can take attachments, just as e-mails do. Attachments and their options are shown in the Attachments panel in the Panel area.

delete attachments icon

Click the Delete button to remove selected attachments from the PDF. Note that this will not remove such files from your computer, only detach them from your document.
 

To open an attachment

open an attachment icon

Select it, click the Open button, set opening preferences in the dialog box and click OK.

The attachment will open in its associated application.

 

save icon

Click the Save button when you are done with attaching files.

 

options icon

Click the Options tool to access the above commands through a drop-down list; you can also have the attachment panel shown by default whenever the PDF document is opened, enter or edit attachment descriptions to tell PDF recipients what they contain and also reset the list of allowed and disallowed attachment file types.

 

Note

Attachments can also be added to PDF files as annotations at a particular location within the document. If you flatten a PDF you can choose to delete attachments that are annotations leaving only an attachment icon, but files attached directly via the Attachments Panel are not removed by flattening. By contrast, during document inspection (Remove Document Elements in the Security ribbon) you can choose to remove all files in the Attachment panel list, and by removing comments, all files attached as annotations can also be removed.
