Zoom in on a photo in a placeholder using the crop function - PPT 2019

For this example I created a new slide layout in the master and added two picture placeholders. If you want to do that go to View - Slide master - click on the Insert layout button - choose the Insert placeholder button and select Picture. Drag two placeholders for pictures next to each other. Close the master by clicking on the Close master view button.

Now make a new slide in your presentation using the new slide layout.

Add the photo you want to zoom in on in the placeholder by clicking on the icon in the middle of the placeholder. Navigate to the folder containing your photo and insert it in both placeholders.

To zoom in, select the placeholder, under Picture tools click Format tab and in the size group click the crop button and choose crop.

Now enlarge the area of the placeholder:

Click and drag in the photo to center it inside the original placeholder.

Click outside the placeholder, the photo is larger and still remains between the original placeholder borders.
