Powerpoint File Size

[Tori]

I've been trying other tips on this site for reducing PowerPoint file sizes
without much luck. We've noticed in particular that our files seem to be
getting bigger over time. The content of our presentations and the way we
prepare them hasn't changed, but a recent presentation was 21MB, whereas one
done a few years ago had twice as many slides but was half the size in MBs.
Any thoughts on what might be causing this? Thanks.

I have tried the suggestions on this site, thanks. Ungrouping and regrouping
helps, but when you have hundreds of charts it gets a little tiresome
(especially if you're given half an hour to do it!). Thanks to both Bills for
the suggestion, though.

Sometimes I have to import all the slides into a new presentation to bring
the file size down. Most of the presentations I get have gone through many
different people, all with fast saves enabled, and this seems to be the only
way for me to bring it down.

Another thing to look for is a single image that is potentially causing all
the trouble. I've had simple looking images turn out to be ten meg.

Tori,

Two suggestions ( if you haven't tried them already):

[1] Check the size of the graphic files.
Gifs and jpegs, etc. can be reduced to 96 dpi for the web and projectors. If
you need to print a hardcopy the dpi should be 300 (PowerPoint says 200, but
most in printing industry start at 300 as a preference and work up. Also bmp
files require more space than the jpeg and gif files (use the gif files as
they support transparency.)

Simply right click on any graphic in the PowerPoint slide and select "Format
Picture" from the flyout menu.
Click on the "Compress..." button in the "Format Picture" dialogue box, and
then make sure the "All pictures in document" radio button is filled in in
the next "Compress Picture" dialogue box.
Choose appropriate resolution for Web/ Screen, Print, or No Change. Click
OK

[2] If you have included music, sound files, you can reduce their size by
converting them to mp3 format instead of wav files.
Here is a freeware progam that I use frequently, called Audacity:
