[jira] [Commented] (PDFBOX-5211) How can I clear unused data?

    [ https://issues.apache.org/jira/browse/PDFBOX-5211?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17361041#comment-17361041 ] 

Tilman Hausherr commented on PDFBOX-5211:
-----------------------------------------

Please attach files that you think have unneeded data, and the "cleaned" version of them. (This is somewhat related to TIKA-2689 where I looked at Adobe Illustrator files)

> How can I delete unused elements (for Photoshop, for InDesign, etc) within a PDF file?
> After applying Adobe DC's optimization options (I posted in the screenshot), I found that a pdf file of 380mb was reduced to around 48mb. This feature is very useful to me. How can I implement it with pdfbox?
> I tried several ways, but couldn't find a way. I need advice.
