Optimize your PDF files and keep file size small
For best viewer experience, keep the file size of your PDF as small as possible. Remove multimedia items, resize images before including them in the PDF (scaling inside the PDF does not change the actual image file size), and most importantly, keep the document short. PDFs are not designed for small screens and if designed poorly, require horizontal scrolling, which makes reading the PDF tedious on small screens for mobile platform users.
If you are using Adobe Acrobat 9, the following steps may work for you:
Open the document in Adobe Acrobat Pro
File > Save As
In the save window, look for Format and select Adobe PDF Files, Optimized
Select the Settings button – you can further optimize from there or click OK to save your optimized file
Multimedia in PDFs is great on normal computers, however, mobile PDFs on different devices don’t necessarily display multimedia objects. Removing the multimedia or, if it’s linked, simply adding a “poster” image will help (a poster is simply an image that will be displayed instead of the multimedia object).
