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