Introduction of other methods

Use? ISlide plug-in has a function of "PPT slimming", which can be divided into two parts: conventional slimming and image compression. In conventional slimming, some redundant contents in slides can be removed, such as useless layout, contents outside slides, invisible contents, etc. And deleting these contents will basically not affect PPT; There are still some things to consider, such as animation and notes.

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