1. Single image compression compresses a single image, which can be easily achieved using the [Compressed Image] function in PPT. We first select the image, and then select [Format]-[Compressed Image]. There are several options for the target output. I Generally choose Web (150 ppi), suitable for web pages and projectors.
2. Multi-image compression We usually use batch compression. Open the PPT file, select [File]-[Save As], and then select [Tools]-[Compress Image].
In the [Compressed Pictures] window that pops up, we check [Delete cropped areas of pictures] and [Email] or [Use Document Resolution], so the pictures in the PPT file have been compressed in batches.
