Conversion Size Headache

I have a 32mb powerpoint file with many jpeg images and when I convert it without editing the jpegs, it converts into a nice small html5 file with the images saved as jpegs, but if I add a border or any formatting in powerpoint to the images, even though the ppt is still small, when converted to html5 it jumps up to 124mb because its saving all the images as large png files. Is there any way around this?

Thank you for the post!
The size of the output file depends on the Compression settings you use in iSpring --Publish--Compression settings tab:

Let me please also suggest that you change the lower resolution in Optimize images for resolution option.

I have done that but even setting compression to the lowest possible setting the png files come out much bigger that in the original ppt. This does not happen with jpeg images. Why is a 32mb ppt presentation with image compression settings at lossy not converting the png to jpegs and coming out at 124mb after conversion?

Hello John!
There can be various reasons why the actual file size of the images becomes bigger after conversion.
For the conversion, iSpring uses not the original images, but the images saved in PowerPoint. This way, the size of the images on a slide can make the difference.
You're welcome to send us your original PowerPoint file and our specialists will take a look at the problem.
