Reduce the size of your presentation files

Thank you very much! Very usefull this information…I always had many problems because of this which ended up files being way to big to send. Cropping them definitely saves some space.Im not the brightest on these type of things.

I just made a PowerPoint 2007 slide show presentation with 82 slides, music (that plays through the slides from beginning to ending) and many slides having animated GIFS. The complete finished presentation is flawless, and it came out very well. It’s really a beautiful presentation (for a retirement party). I saved the presentation on my desktop, and if I click the PowerPoint icon for this, of course it goes into the slide presentation where I can edit any number of slides I so desire or modify it in any way. NOW! No matter what I do to transfer this file… Read more »

Larry, This is going to solve at least part of your problem, the GIFs not working. http://www.ellenfinkelstein.com/pptblog/stop-automatic-compression-of-pictures-in-powerpoint-2007/ The music is probably gone because you didn’t bring the music file to the CD or Flash drive. Unless the music is a WAV file, you can’t embed it, only link to it. If the music file wasn’t in the same folder as the PowerPoint file, you’ll need to start from scratch–move it to the save folder and re-insert it. Otherwise, just make sure that you move the music file with the PowerPoint file. Regarding why the slide presentation doesn’t advance, I’m not… Read more »

Hi! I posted here a procedure about how the images should be reduced:
http://runakay.blogspot.com/2012/04/reducing-size-of-powerpoint.html

That was HUGE help! I reduced my 8 page powerpoint presentation from 12MB to 3.37. Thanks!

you should adapt your photos to the resolution of the projector!
so instead of random dropping large picturefiles to your presentation, first adapt the resolution (eg 1024×768) then save as jpeg (high quality) and you should immediately save a lot of space.

How do you change the resolution of your photos? Do you use Photoshop? What should people use who don’t have Photoshop?

you can resize your photos with all kinds of freeware….

I want to know….how to resize the wave format for the PPS please that is all

Also you can try http://www.imagesizereducer.com online image edit tool.

Hi,
For the image size reducer (www.imagesizereducer.com) if the images are mine ( hi-res scans from my collection of antique family photos ) should I worry about them being saved by that website and used somewhere else ?

Thanks

Out of all the places on the web (including the Microsoft website) this is the only place that helped me compress the images in my presentation. Every other site directed me to the wrong area of the program (under File) THANK YOU for helping me take an 80 MB presentation and making it 34 MB!!!

Glad to help! If you haven’t subscribed to my PowerPoint Tips Newsletter, I invite you to do so. I regularly send out great tips that will help you in all areas of presenting and PowerPoint. Here’s the link: http://www.ellenfinkelstein.com/ppt_submit.html.

Check also the MASTERslide, in my case big size graphics (700k in my company…)are saved there.

Thank you for the most useful article on the topic! I see a puzzling effect, where if I attach my 8 MB presentation to an email, that simple step makes it a 10.5 MB file. When I save that emailed file to disk, it is again 8 MB. What is going on here? Has anyone solved this? Also, the file jumped from being a 5 MB file to an 8 MB file quite quickly, so I am wondering if it attached some referenced file or similar, but I don´t see anything like that and there are no alerts or messages.… Read more »

I’m having a hard time saving my slide show(pictures around 500) How can I save it?

@Rosie – quick answer is: files on your computer are stored in binary (more efficient). Email is transmitted as text (less efficient).

As such, re-encoding the binary data (PPT) as text makes it larger, because the efficient data is being represented in a less efficient way. And that’s pretty much true for any email attachment.

Also, I think it’s important to mention that using PowerPoint’s compress feature will noticeably degrade the quality of the photos in your presentation. As such, professional presentation designers who need to project the finished deck for large audiences–at conferences, for example–don’t use it. And if you’re working with an agency and decide to compress a deck sent to you by them, you’ve increased your cost by hundreds of dollars (depending on the length of the presentation) because they now need to go back in and replace all the photos you’ve degraded. But don’t take my word for it. Insert a… Read more »

Dave, I think that designers notice this more. I just took a screenshot of your comment — all small text — and put it on 2 slides. I compressed the 2nd one to 96dpi (it was the only option available), which would normally be very low. I can’t tell the difference on my 23-inch monitor. But I definitely agree that you should check the results before and after if there’s any detail in the image to make sure it’s OK.

Hi Ellen, not contradicting you but I’d like you to take the same screenshot and size it down to 60%. Then leave one untouched and compress the other. You should immediately see that the compressed version is almost illegible.

Larger text/logos/graphics won’t be as noticeable. It’s when the images get smaller with the greater need for detail, that you’ll see the difference.
