Why is the PPTX file not reduced?
Select View details on any current Microsoft Office or PDF file in NXPowerLite, to see a size audit of the content inside and what might be preventing further reduction.
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.
Look inside PPTX files with BetterZip Quick Look
We’ve taken a look at many archive apps for macOS and have found a free Quick Look extension that enables you to see the breakdown of the content within a PowerPoint file. To prepare your macOS for seeing your PPTX content, follow our easy 3-step guide to installing the BetterZip Quick Look extension.
Once BetterZip Quick Look extension is working take a copy of your PPTX file and rename the file adding ‘.zip’. Now select the file in Finder and press the spacebar to start Quick Look. You will see a folder treeview, where you can browse through the folders to see where the large content is lurking. The folders are named for the content they contain.
Jump into a folder to see what individual files are causing the size problem and follow the instructions above to compress what you find.
What content is still large?
Content is organized by size, with the largest items listed first.
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, so here are some instructions for compressing WDP and EMF images.
Fonts

Embedded objects

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.
