Keynote vs Powerpoint file size

I just created a 15 slide blank presentation (800x600) using the White theme. When I export this to PowerPoint, the resulting file is 68k. I then placed one 800x600 image on each slide, exported THAT to PowerPoint, and the file is 3.8 megs. When you start with a Keynote presentation (not importing from PowerPoint) can you do the same thing and come up with a similarly sized file?

I did as you described. 15 slide 800x600 blanks on white results in 296 kb on keynote, exported to PowerPoint and got 68k, same as you.
I then placed 15 images on each slide, all 800 x 600 except 6 which because of portrait shape or original wide panorama were 800 x 450. (to go to 600 would have caused distortion) This gave me 1.4mb on Keynote and only 1mb on the version exported to Power Point.

I guess that's the solution. 800 x 600 on white blanks. (I tried it as an attachment, on Keynote it was 3mb and PP just under 1mb.
Unless you have any more words of wisdom, may I say thank you for your patience and guidance.
Please confirm, so I can add the brownie points

Not sure what part about having a different resolution was causing the problem, but it appears that you've hit upon the thing that allows you to have a SIGNIFICANTLY smaller file, suitable for emailing! 🙂

Making progress. Have now added music and total slides now 17. Also added text - titles to each picture.
The first 'tune' I added was an AIFF and the memory jumped up to 34mb, but I changed the tune to another at MP3 and with all additions is now 4.5mb, which is acceptable for e-mail attachment.
The exported version to PowerPoint came out at only 1.2mb.

I then sent both as attachments to my wife's Macbook via normal Mail. Her Mac is in the same room, but it went via normal server. They appeared on her screen as 4.2mb (Keynote) and 1.2mb (PP). Both played (full screen) but only the Keynote version included the music.

I have found that when friends send me pps presentations I rarely, if ever, get the audio accompaniment.
I explored the PowerPoint 'Help' and sent again the pps version as a 'package', but that did not work either. When opened, it tried to find the right tune, but it failed. Otherwise the slide show ran through normally.
I assume that this means that any slide show sent to anyone with a PC Windows computer will not deliver any music - or any audio whatever ?

If you know how to get the audio included as part of the PowerPoint transmission, I would be grateful. Not all Mac owners have Keynote, relying on MS Works or even '98.

Otherwise, that's enough for the meantime, and once again thankyou.

Just as an aside, every Mac user CAN have Keynote. They can download the trial here.

http://www.apple.com/iwork/trial/

And after 30 days, they can no longer Edit or Save, but they can still view any Keynote file that is sent to them.

For the audio question, see if you can find a list of types that PowerPoint will accept then try using those. You may need to get an app that will allow you to encode as WMA, for example, if that's all PowerPoint will play. Keynote plays just about any standard format since it's media content is supported via QuickTime.

Didn't know that they could still view after the trial period. Will pass that info around.

Will pursue the PowerPoint audio question.

bye for now..

Just to add that having completed the Keynote presentation with 17 slides and music, I made a copy, removed the music, and exported it to PowerPoint.
I then opened the PP. Pulled the iTunes MP3 music into the PP 'Gallery', then added the music through Insert/Movies and Sounds/Sounds from Gallery.
The save as PowerPoint Package
This gave me a folder which included the MP3 and totalled 5.3mb
I sent it through the server to my wife's Mac where it appeared as 6.9mb
Opened with PowerPoint, it played fine, but opened with Keynote the music was absent.
So I opened the PP folder which has three items (one is the MP3 tune), then opened the keynote version, opened the inspector, dragged the MP3 from the PP folder to the audio window and then the Keynote version plays with music.

By this roundabout route, it would explain why those pps slide shows don't bring the music with them -- maybe. Anyway, I've learned a lot .. thanks yet again to Kyn.
Will check this as answered

I'm having the opposite problem. Namely, when I create a presentation in Keynote and export it to PowerPoint the size of the PowerPoint slide is exponentially greater than the original Keynote presentation.

Also, the bitmaps that have clear backgrounds end up showing a white background in PowerPoint.

Any suggestions?

Thanks in advance.

PowerPoint doesn't display .png images, that's why they're getting converted to images with white backgrounds.

Also, if you're using one of the built-in themes, then it's pulling images from a common area on the HD (unless you tell it to package the images with the presentation). That's why if you send them to another Keynote user, they're tiny files BUT still viewable. Exporting to PowerPoint forces Keynote to include all those images in the export and that could lead to the file since increase you're seeing.
