If you’ve resized or masked a very large image file, and you want to save the image file as part of your Keynote document (so that you can easily transfer it to another computer), but you want to keep the document size to a minimum, you can choose to save only the smaller (cropped or shrunk) version of the image in your presentation.

Before you reduce the image file size, you must save your document. For details about how to do this, see Saving a Document.

To reduce the file size of your document, do either of the following:

  • To reduce the file size of an individual image that you’ve masked or resized to a smaller size, select the image and choose Format > Image > Reduce Image File Size.

  • To reduce the sizes of all masked and resized (shrunk) images, and shortened videos, choose File > Reduce File Size.

    To learn more about reducing the size of movie files, see Reducing the Size of Media Files.

Note:  After you’ve reduced the size of masked or shrunk image files, you won’t be able to restore them to their original size. If you later want to restore their original size, you must add the original image files to the document again.

Images used in image fills or with action builds cannot be reduced in this way. Some types of image files also may not be reducible.
