Hi,

First, please install the latest version of Acrobat Reader from the App Store. The latest version (as of January 17) is 18.12.00.

When you open a PDF document containing built-in bookmarks (table of contents), the Bookmarks icon appears in the top bar. (It's the third icon from the left.)

If you have a small iPhone such as 5s or SE, please tap "..." instead. The popover should show "Bookmarks".

The pre-installed PDF document called "Welcome" contains built-in bookmarks as well. Please open it to see if you can find the Bookmarks icon.

Hope this helps.

Yes, my pdf file contains table of contents and I can view it easily with iBooks or on laptop. But I failed to do so with acrobat reader. Can you tell me how I can do that with this app?

Hi,

Please note that not all PDF documents contain bookmarks (table of contents). It is up to the author of a PDF document to decide whether (or not) to add bookmarks.

Would you please try opening the same PDF document in (a) iBooks on iPhone/iPad or (b) the desktop version of Acrobat Reader on a Windows or Mac computer to see if the PDF document actually contains bookmarks (table of contents)?

Alternatively, you can attach your PDF document in your next post, if you don't mind sharing it publicly.

Thank you for your help.
