When I insert a PDF at the end of another PDF, the bookmark destinations in the inserted the PDF do not update correctly.
For example, on its own, the PDF I want to insert has a bookmark pointing to page 10. The main, receiving, PDF has 100 pages. When I insert the PDF, the page-10 bookmark goes to page 10 in the main PDF. It's supposed to go to page 110. So Acrobat is not offsetting the destinations to account for the prior pages in the now-combined doc.
It's a problem with the file, not Acrobat. Is there a way to fix the file other than to manually offset every page number in every bookmark? It's over 2,500 pages and there are dozens and dozens of bookmarks.
I don't think it matters, but I'm using Pro DC, 2021.001.20145
Ah, I figured it out. Well, your question prompted me to figure it out. 🙂
Yes, that would do it... If you're interested, I've created a (paid-for) standalone tool that will convert those links to "regular" links with a "Go to a page" action, which means they will update automatically if the file is edited.
