Compress Photos in PowerPoint 2010

PowerPoint Compress Pictures Dialog Box

1. Compression Options
   • By default PowerPoint 2010 assumes that you want to compress only the selected photo. Uncheck this box if you want to compress all photos in the presentation.
   
   
   • If you have cropped any parts of your picture(s), those parts are hidden from view but not deleted. Uncheck this box if you do not want to delete any portion of the cropped picture(s).
2. Target Output
   • In the Target output section there are four photo compression options.
     • Print (220 ppi): excellent quality on most printers and screens - largest file size
     • Screen (150 ppi): good for webpages and projectors
     • E-mail (96 ppi): minimum document size for sharing
     • Use document resolution: By default, PowerPoint sets the resolution for pictures at 220 dpi. If your inserted photos have a lower resolution, then that resolution would apply.
     In most cases, choosing the option, E-mail (96 dpi), is the best selection. Unless you plan to print out quality photos of your slides, this option will reduce the file size by the greatest margin. There will be little discernible difference in the screen output of a slide at 220, 150 or 96 dpi.
3. Click OK to apply the settings and close the Compress Pictures dialog box.
