Think PPT file is too big, you can try to compress PPT, there are many ways to deal with it. Here's a way.

For example, using the iSlide plug-in,

There is a PPT slimming function inside.

After clicking, you can see that it is divided into two parts: conventional slimming and image compression.

In conventional slimming, you can get rid of some redundant content in the slide, such as useless layout, content outside the slide, invisible content and so on. And the deletion of these contents will basically have no effect on PPT; There are still some things to consider, such as animation and notes.

In image compression, we can compress the image materials used in PPT to reduce the space occupied by images. The degree and method of compression can be set by yourself, but this kind of processing may have a certain impact on the effect of slide show, so it should be considered.
