Other than purchase another piece of software, is there
any way to reduce the size of a PowerPoint file?

Thanks

If file size is determined by not appropriate scaled bitmaps you can
Edit|Cut and Edit|Paste as (Jpeg) to scale pics to used bitmap size

Hans,

This appears to not reduce the filesize at all.
Or have I misunderstood your answer?

Hi

I'm not sure if this will help since I have been having a few problems with this myself, but its worth a try. I run on MAC OS X at work, which makes it challenging to work with Microsoft products at times. This could be a MAC only solution. Once you are finished with your powerpoint, save the entire presentation as JPEG. This will make a new folder with each slide as a separate file. You will now use a sepate file in JPEG format to build a new powerpoint presentation by inserting a picture of each slide. You don't lose any picture quality this way and your file will shrink dramtically

But, be careful. This method only works if the pictures you have inserted in your original powerpoint before converting to JPEG do not have any manual changes made to them (such as cutting out a corner). If you have changes, the JPEGS produced then have lines in the pictures when you made the manual changes. I hope this helps.

Perhaps my english is not the best :-)

Cut&PasteAs reduces filesize caused by oversized bitmaps.
Take a bitmap from a digicam lets say 2048x1635 px and size in PPT to
12x16cm - Scaling about 44%, dependig on resolution Px/cm.
Saved filesize in ppt about 1 MB.

Cut&PasteAs (JPEG) you will have a compressed (JPEG) bitmap about
600x450 px scaling 100% now. A massive reduce of bitmap size...
Saved filesize in ppt about 60 kB.

Additionally: If you get rid of some OLE-server (you may have by
inserting pics via paste) this way you will cut down filesize to 1/10
over all...

HW,

I see.....

The "Paste Special" as "picture JPG" is a new option in powerpoint 2002
(perhaps 2000) but is not available in ppt 97.

I did some tests.

ALL insert picture from file:

(1) insert 1024x768 jpg. Save it - ppt filesize=85kb
(2) cut and "paste special - as pictureJPG" - ppt filesize=69kb

I guess this reduction could be because powerpoint sets a 'lower'
compression quality for when it "cut's the JPG or pastes the JPG"

If you avoid the normal "paste" in powerpoint when inserting your pictures,
you avoid the OLE bloat.
If you size your images to the correct pixel count before you insert the
pictures into powerpoint your avoid the ppt filesize bloat.

It's a good trick to know though.

Cheers

With files at "normal" size, you won't see a big difference.
But try inserting a really large file, then shrink it down to, say, 1/4
screen.
Then do the copy/paste special as JPG trick and you should see a bigger
diff.

When you copy/paste this way, what you get back is a copy of the image at
the size PPT's currently displaying it at. IOW, yoru 2048 x whatsize image
reduced to 1/4 screen at 800x600 pastes back as a 400x300 jpg. Which will
be a mite smaller bytewise, as you can imagine.

Works even more impressively if you start with a non-JPG image to begin
with, I'd bet.

Yeah...the tests with one PNG image went from something like 400kb to 100kb

[CRITICAL UPDATE - If you are using Office 2003, you should install this
update as soon as possible. From PowerPoint, choose "Help -> Check for
Updates".]

Hello Steve,

Currently, PowerPoint 2002 and PowerPoint 2003 provide an image
optimization feature (choose "Compress Picture" from the Picture toolbar),
but other kinds of optimizations (including lossy conversion of OLE
objects, removal of hidden objects, etc.) are not provided through it's
user interface (and even determining which content might be a candidate for
optimization can be difficult).

If you (or anyone else reading this message) think that PowerPoint should
provide better content management tools for finding, changing, replacing,
deleting, OPTIMIZING, etc. linked, embedded, and native content (without
have to resort to VBA or 3rd party add-ins), don't forget to send your
feedback (in YOUR OWN WORDS, please) to Microsoft at:

As with all product suggestions, it's important that you not just state

be implemented by Microsoft. Microsoft receives thousands of product
suggestions every day and we read each one but, in any given product
development cycle, there are only sufficient resources to address the ones
