To deflate the size of a PDF.
If you have Acrobat:
1. Open PDF in Acrobat
2. Go to advanced menu
3. Open Optimizer
4. Choose Discard User Data
5. check the second item down
6. save as a new file.
Compare sizes, usually the size of the PDF will reduce as much as 50% if
not 70-80%. Further reductions can be had by:
7. Go back to Optimizer
8. Click on Fonts
9. If there are any unembed any duplicate font types. you only need one
version of each font type used to make a very good looking PDF.
often doing both of these can decrease a file that was 4 mb down to 50K
in size.
10. If not Fonts go to Graphics
11. Set graphics so if they are to used only online to no more than
150dpi. Even if they are to be printed on an inkjet or Laser
printer they should be no more the 300dpi or 600 dpi
Once you gotten size the way you want it, save, then insert into your Word Document.

Crop, re-sample, and compress the pictures BEFORE you insert them

The "compress images" function on the PC is not actually compressing
the images. It can't: if they are normal JPEG or GIF or PNG they
are already as compressed as they can be.
What it is doing is removing pixels to lower the resolution from
whatever the camera gave you (chances are that's about 2,400 dpi)
down to 96 dpi. You can do that yourself before you put the pictures
in.
Before you down-sample their resolution, first use graphics software
(iPhoto will do at a pinch, but it's not easy to drive for this kind
of thing...) to crop the pictures so they show only what you want
the reader to see. Then set the SIZE of the picture to be the size
you want it to print at, and the resolution to 96 dpi.
Instead of relying on Word to remove "some" of the bloat for you,
clean up your own pictures and then you will be fully in control.
Your PDF from the Mac will end up smaller than Word 2007 gets it :-)
You need to know how your recipients will use your document.
If they are going to read it on screen, set the resolution to 96
dpi. A computer screen won't show them any more so there's no point
in sending any more. Express the pictures in JPEG because the
screen will show all the colours there are, but crank the JPEG
"quality" down to 50 per cent (not lower than 40 per cent). On
screen they can't see the difference, but the file will shrink
dramatically.
If your recipients will want to print the document on an Office
printer, set the resolution to 150 dpi, but express the pictures as
GIF or PNG. Use GIF for the smallest file size but the colours will
be off. Use PNG for the best looking result.
For printing on high-end commercial printers, set the resolution to
at least 300 dpi. For a good-looking job, take it up to 1200 dpi.
Send the pictures in JPEG, but lift the quality above 80 per cent or
you will get artifacts.
For commercial offset printing, leave the DPI and quality as high as
you can get them, and don't try to email the result, it's too big
:-)

When generating a PDF from Word, the filesize increases tenfold
(from 3MB to 30MB).
The same Word document on my PC (after using the 'compress images'
function available in Office 2007) generates a 100 KB PDF file.
How can I set the compression level on my MAC to get the same
filesize as on my PC?
