I have an 8 MB pdf file that definitely doesn't need to be that big. How can I reduce the size of this pdf file in Windows?

I do not know of actual programs for compressing .pdf files as .pdf however your best bet would simply be to try using alternative PDF creation utilities as I have seen file size change dramatically between them.
I have never done a 8MB PDF, however I did do a 2MB one and I noticed that by using Bullzip, Flashpaper and the official Adobe Acrobat created a diffrence of over 60% in some cases... Generally, Adobe came in best, Flashpaper second and Bullzip last. (thre are a load more tools available, but these are the ones I tested.
Some of these utilities also enable you to compress the resources and control the quality. Whilst Bullzip is free, you may want to try a demo of the others and see if they can help you.

We can add some opensource program for dealing with images as gimp or imagemagick.
The first, GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. Something like Photoshop but opensource. Huge program: you can use e.g. to create a pdf from scanned images.
The second, Imagemagick is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PNG, Postscript, SVG, and TIFF.
With the second it's possible to convert in pdf using expressly the option -compress jpeg
specifying the geometry and size:
convert -geometry 2480x3508 -compress jpeg Orig.pdf -page 2480x3508 Final.pdf
Note that you may want to decide with which definition to have the final document: in the above case I choose A4 format 300 dpi. Below a table to remember those dimensions in pixel for each definition of oint Per Inches, PPI.

A4 600 4961 7016

Letter 400 3400 4400
Letter 600 5100 6600
Letter 1200 10200 13200
Convert is a command that comes with Imagemagick.

I use PrimoPDF (free) and choose "Ebook" as the "file size" "document type". (You can choose smaller (lower quality) file sizes or larger (higher quality) file sizes. The Ebook looks pretty good.
This reduces our 16 full color catalog (with a few small photos per page) to 2.4 MB and still looks fairly good.

If I were you, as a simple solution I would try PdfCreator and print that pdf file as it is.
I'm sure it will make the size about half of the initial one.
1Wow - I used Bullzip pdf printer, and it reduced it to 569 kb – Moe – 2009-08-13T00:58:35.000
Good to hear! Out of curiosity, what did you use originally to create the pdf file, or was it something you downloaded from someone else? – William Hilsum – 2009-08-13T02:07:03.777
It was sent to me by a friend who created it with Comiclife – Moe – 2009-08-13T03:27:01.347
