PowerPoint 2010 Picture Tools

Reducing the file size in PowerPoint is always a good idea, particularly if your presentation is photo intense, such as in a digital photo album. Using many large photos in your presentation can cause your computer to become sluggish and possibly crash during your time in the spotlight.

Photo compression can quickly reduce the file size of one or all of your photos at the same time. This is a great tool to use if you must email your presentation to colleagues or clients.

  • Click on a picture to activate the Picture Tools, located above the ribbon.
  • Click on the Format button if it is not already selected.

  • The Compress Pictures button is located on the left side of the ribbon.


PowerPoint Compress Pictures Dialog Box

  • 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).
  • 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.

  • Click OK to apply the settings and close the Compress Pictures dialog box.
