Reducing File Sizes by Managing Photos, Screenshots, and Web Images

PowerPoint presentation file sizes can become rather large when they include photos, screenshots, and/or images harvested from the web. They take up unnecessary disk space, are difficult to share/email, and are a drag on a computer's processor. Without getting into too much detail (this is a very broad and deep topic), there is a technique that you can use that will very quickly reduce the picture sizes. Copy the photograph into your presentation and then save it as a .jpg picture with a different name than the original image onto your desktop. Then drag the newly created .jpg onto your slide. You should have reduced that picture/screenshot/web graphic by between 3/4 to 2/3 of the original graphic size (kBs not physical dimensions).

Be advised that .jpgs use compression, so there is a slight reduction in quality. That's why you want to give it a different name than the original image in case the original was a jpg and you didn't realize it.

One important consideration: if you have an image that has a transparent background, it is in .png format. If you need that transparency do not save as a .jpg, as jpgs do not have transparent backgrounds.

The instructions below will explain this very easy technique.

  1. Right click on the image you wish to reduce
  2. Click on Save ad Picture
  3. Give it a new name, click on desk top (on left vertical margin), select .jpg format, and click Save.
  4. Then drag the newly created image onto your slide and finish layout/development of slide.
