PowerPoint presentations can become very large when you are inserting images into the slides. One option you have to get around this problem is to manually convert all the graphics to a more compressed file type such as a JPG.

An even easier method is to have PowerPoint take care of this for you. Once you have your presentation open, under Picture Tools, on the Format tab, in the Adjust group, click Compress Pictures.

You can select which pictures you want to compress. You can compress selected pictures or you can compress all pictures in the presentation. You can also change the resolution of the pictures. The resolution for Web/Screen is 96dpi and 200 dpi for the Print option. You can also have the cropped areas of pictured deleted (in case you didn’t know, the cropped area of pictures is usually just hidden, not deleted).
