I converted my iPad notes to a PDF, and the 70 page PDF file is huge (1.1 GB). I bought the Adobe program to convert to MS Word, but the file is too large. How can I reduce the size of the PDF file, or break it into smaller pieces, so that I can convert to word and hopefully have a smaller overall file size. This document has color photos and text. I don't know what makes it so big but any hints to reduce size and help convert will be appreciated.
