I'd like to know HOW to correctly use ppt minimizer. I used it to try to decrease a ppt file from 75 to less than 50 mb, without losing too much quality. However, in every compression ( low, normal, high or custom ) I either get no reduction of any significance or I get such poor quality it is unusable... and the maximum compression I got was 9,3%. not 96.
my 75 mb file became 68 mb.

so, if anyone knows... HOW do I reduce my 75 mb file into less than 50 mb, without losing too much quality?

thank you ;-)

I'm guessing use text only - no graphics - no sound. Text compresses the best.

Thankx BuBBy. text only eh? but eh... ... ... TEXT ONLY? a powerpoint is usually meant for visual fun is it not? ( in my life anyway... )

Uhm BuBBy....?

All I do is put high res pix to music ( mp3) with a very precise and specific timing. This gives me ppt files that are very large.. I use the high res for quality. I need the quality of the colors and sharpness of the pic in this case...

so... is it impossible to reduce the file by that much then?

( I'm just a novice and learning along the way... ;-))

It's is those sort of powerpoint presentations that people are saying the photos aren't as crisp as the uncompressed photos were..... well duh.

The 96% is a "best case" usual compression rates are probably much more conservative. With graphics (ie. photos) the more compressed you make it - the more pixellated and more artifacts the graphics will likely have. So a sliding scale of higher compression results in lower image quality. You need to decide where the "happy medium" lies.

Just remember with compression (sound sample rates, graphic display quality etc) there is no free lunch.

I don't understand why one would need to lose quality from a presentation.

Why compress it, thumb drives, even a 2gb are less than £5 now days.

So storage should not be a problem.

Lee, compression would be nice for backup purposes. If you want to back up more than a few things at a time, that is!

That is, if you are doing your backups by yourself instead of relying on software. That's what I do to have the most control and most reliable restores possible.

There are lots of reasons for compression - economies of scale for example.

Compression is very handy for example in a training environment where a "term/semester" of lecture notes are stored on multiple - say 14 weeks x 2 presentations. If these can be reduced in size each from 50MB to 25MB (50% reduction) - and there are 100 students in the course for the semester, The reduction permits the notes to be distributed on a single CD-R instead of two CD-R's. A saving of 100 CD-R's.

Same goes for sending a "funny" powerpoint to all of your friends - your ISP might have an upper size limit for maximum file size of attachments that can be send - a bit of compression might let you "limbo" under the ISP filesize bar. Users who are on dial-up might appreciate getting a PPT that is 6MB instead of 12MB - especially if after they wait for it to download, they don't find it particularly amusing. ;)

Sending emails with pps files is quite popular, but providers often limit the maximum size of att.
So PPTMinimiser may be quite useful.

As I see it ,it is no use displaying the full power of high resolution pictures to a computer which has a res of 1024x768.
But squeezing pps or ppt to the highest compressing (96% ) is madness.
It is like creating wav files with the poorest quality available and complain about the quality.

PPTMinimizer with an embedded wav compresser feature ...this could be a suggestion for future development of this great program. :)

@BuBBy
Sorry, but I didn't see your post when creating this one.

After thinking about it all, there is one thing I do not understand.

with a xp powertoy, one can resize pictures from high res to fit a small screen. without too much quality loss, that's just it... not much quality loss. Why then, is it almost impossible to take a ppt presentation made with high res pics, and NOT be able to compress it without that quality loss... I do not understand the difference between for instance xp resize pictures before making the ppt and using ppt minimizer afterwards... ... ???

I need small files for putting it online, but I need crisp and clear quality... somehow it seems it's not possible to do both... grr. ;-))
