In this example, the majority of the size is accounted for by two videos, although there is also over 8 MB of fonts. Once you know what content is not getting compressed, follow the links below for specific help.

More powerful analysis with Slidewise

Our Slidewise add-in takes you a big step further, allowing you to link up the large content with exactly where in the presentation it’s located, allowing you to more quickly fix it.

Open your PowerPoint file and click to open Slidewise. It will display a complete index of the content in your file, with the associated file sizes. In this example below, you can easily see that there are two 3D models accounting for almost 88 MB. If you expand that in the tree you can double-click on the models to jump to them in PowerPoint.

What content is still large?

Content is organized by size, with the largest items listed first. The number of items are indicated in parenthesis, for example, JPEG (20) = twenty JPEG images.

Images

Most images will compress well with NXPowerLite. However, Enhanced Metafiles (EMF) and WDP images do not compress well. Here are instructions for compressing WDP and EMF images.

Fonts

Embedded objects

Try the Strong Compression profile in NXPowerLite which can compress some embedded objects automatically.

Don’t see view details?

If you don’t see the View details feature in your version of NXPowerLite, you probably need to update to NXPowerLite Desktop 11.

One final thing to check…

Sizes are listed in KB in NXPowerLite, anything below 1,000 KB (1 MB) is reasonably small and should be easily transferred by email. Most email caps have risen to 5 - 10 MB even in restricted scenarios, although there are still some areas where the limits are much tighter.

If you come across anything else in a presentation that is making it too big and you can’t fix it—then please contact us—we love hearing about content that is causing size issues in PowerPoint and we might be able to help.
