  2. On the Picture Format tab, in the Adjust group, select Compress Pictures.

Delete image editing data and lower default resolution

When you edit an image, the data of the original is retained by default. Discarding it means that you can't restore the changes you make, but it will reduce your file size. Lowering your default resolution also reduces your file size.

  1. Go to File > Options > Advanced.

  2. Under Image Size and Quality, do the following:

    • Select Discard editing data. This option removes stored data that's used to restore the image to its original state after it's been edited. Note that if you discard editing data, you won't be able to restore the image after you edit it.

    • Make sure that Do not compress images in file is not selected.

    • In the Default resolution list, select a resolution that is 150ppi or lower.

      Set the image size and quality

Reduce the character set of embedded fonts

To make your presentation more sharable with others who don't have the same fonts in their system, it's typical to embed the fonts you use. However, embedded fonts will increase your file size. To minimize the file increase, embed only those characters used in the presentation.

  1. Go to File > Options > Save.

  2. Under Preserve fidelity when sharing this presentation, select Embed fonts in the file, and then select Embed only the characters used in the presentation.

    Embed fonts in the file

    Note: If you've used custom fonts and want others to edit the presentation, select Embed all characters.
