Currently I am importinh bitmap images for my
presentations, but find that it gets rather large. I
have tried compressing them, but they are still large.
Could you please advise me on PNG images and if this is
the best to use when creating a powerpoint presentation.
THANKS!
 
PNG images are great to use in PPT. JPGs also work well, as do various other
image files. It just kinda depends on what image you are working with.
Regardless, though, you'll be safe with PNG, and it should cut your file
size quite nicely.
 
Petrina,

PNG gets my vote.

Also remember to use the "Insert>pictures>from file" method.

And Turn off something called "Fast Saves" in Tools>Options in powerpoint.

Cheers

1. I don't think it will make a lot of difference whether you
use gif, png or jpg.

2. Are you sure that the images are bit mapped, i.e. raster? If
they are Excel Charts, for example, they can be created as vector
images rather than bit mapped ones and this might be substantially
smaller provided you import them as metafiles (using
Edit | Paste Special) and don't
inadvertently convert them to bitmap by editing them in a raster
package first. If your images are photos then they are certainly
bit mapped so this point will not apply to you.

3. If you save your powerpoint presentation in HTML format
(File | SaveAs) it will create a subdirectory with all your
images one per file. Check their file sizes in case there
are some very large files and focus on reducing those.
Maybe some are objects that can be converted to bit maps.
Simply pasting such an object into a package such as the
free xnview package (xnview.org) will convert it to a bit
map.

4. The inexpensive utility at nxpowerlite.com is quite effective
at reducing powerpoint file sizes. You just give it the name
of a powerpoint file and it produces another one which is
much smaller but otherwise visually the same. You can try it
for free to see how well it works on your file.
