Automatic Bookmarking from Word to PDF

Hi Forum,

I am looking for an easy way to convert a word document which has a table of contents incorporated within and also the correspoding pages relating to that TOC into automatic bookmarking into the PDF, so in effect it will capture the TOC and the corresponding headers from level 1 2, 3, & 4 with automatic bookmarking saving the need to manually bookmark.

Thanks in advance,

James.
