Microsoft PowerPoint presents a blank canvas for people to put together presentations for business or personal use. This canvas does not matter how large the final product will be. PowerPoint files filled with high-resolution images, embedded audio files, and other large objects grow in size. Because PowerPoint loads the presentation into memory, these huge presentations can grow so large that older PCs or Macs can’t play them without slowing down.
However, optimizing images and sound before putting them in a PowerPoint presentation will take at least some of the bloat.

Optimize photos for use in your presentations
Optimize your photos , before paste them into PowerPoint. Optimization is reducing the total file size of each photo – preferably to 100 kilobytes or less. Avoid files larger than about 300 kilobytes.
Use an image optimizer if your presentation contains too many large photos.
Compress photos in PowerPoint presentations
Nowadays everyone wants to get as many megapixels as possible on their digital camera to get the best pictures. They don’t understand that high-resolution files are only needed for: printed photos, not for the screen or the web.
Compress photos after pasting to reduce file size, but optimization is the best solution if possible.
Crop images to reduce file size
Cropping images in PowerPoint has two bonuses to your presentation. First, you remove unnecessary details in the image that are not necessary for your point of view, and second, you reduce the overall file size of the presentation.
Create an image from a PowerPoint slide
If you’ve already added many photo slides to your presentation, perhaps with several photos per slide, you can take a photo of each slide, optimize it, and then insert that new photo into your new presentation. PowerPoint includes tools that allow you to create images from PowerPoint slides.
Break your large presentation into smaller presentations
You can also split your presentation into multiple files. You can then create a hyperlink from the last slide in Show 1 on the first slide Show 2 , and then close Show 1. This approach gets a bit more cumbersome if you’re in the middle of a presentation, but it would free up a lot of system resources if you were just opening Show 2.
Having all the slideshows in one file constantly uses your RAM, preserving images from previous slides, even if you have a lot of slides ahead of you. Closing Show 1 frees up those resources.
Why isn’t music playing in my PowerPoint presentation?
Music problems often annoy PowerPoint users. Many presenters are not aware that only music files saved in the format can be embedded in PowerPoint. WAV . MP3 files cannot be built-in , but only connected to at the presentation. WAV file types are usually very large, making the PowerPoint file even larger.
