One of PowerPoint's greatest qualities is that you can get all sorts of content from disparate sources and add them all within one presentation to create a unified document. Pictures are one of the most important content types you add on your slides. However, each picture you insert may have different resolutions, and thus even though you may have sized your picture to look like a small postage stamp on your slide, it may be increasing your file size by several megabytes because PowerPoint may store the original, larger image.

You can of course manually compress pictures in your presentation. Even better, you can set the document resolution for any presentation. Document resolution is a presentation-specific resolution you can set. This option will compress pictures you insert automatically to the default resolution you set.

Choosing the high fidelity resolution ensures that pictures are not compressed unless they exceed the size of the document canvas, that minimal compression is applied if necessary, and that the original aspect ratio is maintained. In PowerPoint 2016 and newer versions, the default image resolution is already set to high fidelity. In PowerPoint 2010 you can change the orientation of slides to make your presentations look good in wide screen or other screen sizes. To control the Aspect Ratio in PowerPoint presentations you need to change the Page Setup. To configure a special Aspect Ratio for your slides, you will need to go to Design tab.

If you have multiple presentations open, click within the box showing the presentation name (highlighted in red within Figure 3, above). From the drop-down list that appears, choose the presentation that you want to set the default picture resolution for.
Now, click within the box beside the Default resolution option, that you can see highlighted in blue within Figure 3, above. This brings up a drop-down list, as you can see in Figure 4.

By default, High fidelity option is chosen. You can choose any other resolution value. Essentially, the larger your ppi value is, the higher the quality of your images will be. This also means that the compression level used will be lesser. In our Compress Pictures in PowerPoint 2016 tutorial, we explain the compression levels that 330, 220, 150, and 96 ppi signify.
Once done, click the OK button (see Figure 2, shown earlier on this page) to apply the changes.
