Go through your slides and remove any images that don’t add any true value to your presentation.
A second option is to remove artistic effects from images.
Finally, considercompressing your images.
Select an image in your slideshow, and click “Compress Pictures” in the Picture Format tab.
Then, you might either choose to compress the image you selected or all images in your file.
Click File > Info, and choose the “Compress Media” drop-down button.
There, click “HD” or “Standard” as alternatives to the Full HD option.
Compressing the media in your presentation will also remove embedded subtitles and alternate audio tracks.
