If you’ve packaged your presentation with loads of pictures, you may notice that your file size has increased dramatically. If you plan to upload this presentation to the web, users who wish to download the presentation may have to spend a bit of time waiting for the download to be completed. You can save this annoying time lag by reducing the file size of the images in your presentation without losing the quality of the images and in turn reduce the size of your final presentation. In this Microsoft PowerPoint 2010 tutorial, you will learn how to reduce the file size of pictures in your presentation and thereby reduce the size of the overall presentation.
Take the simple example of a cropped picture. You might assume that when an image is cropped it reduces in file size. On the contrary, the cropped regions still form part of the image data file and add to the file size.
Open up a presentation and go to the slide that includes a cropped picture. On the Picture Tools Format tab, in the Arrange group, click Crop.You’ll noticed that the cropped areas still form part of the picture. You can eliminate such unwanted data by compressing the picture. Ensure that compression is saved before proceeding with picture modifications such as applying artistic effects, removing the background and other editing options.
In this tutorial, let’s see how we can eliminate the hidden picture information and reduce the file size of pictures in your presentation.
