With high-resolution cameras and the advanced cameras on smartphones, capturing high-quality images is easy. However, those photos may be too large for the slides in your PowerPoint presentation. If you have a large number of images to include in PowerPoint, speed up the process of resizing them without repeating the tedious task for each picture by creating a macro to do the job for you.

Instructions in this article apply to PowerPoint 2019, 2016, 2013; and PowerPoint for Office 365.

Add the Images to PowerPoint Slides

Before you begin, insert all the images you want to use in the PowerPoint presentation.

  1. Open a PowerPoint presentation and select the first slide that will hold an image.

  2. Go to Insert. 

  3. Select Pictures > Picture From File.

  4. Choose an image on your computer and select Insert.

  5. Repeat this process to add photos to the other slides in your presentation.

  6. Do not be concerned that the photos are too large or too small for the slides at this point. The macro will take care of resizing images so they are the same size.

Record a Macro to Resize the Images

After all the images have been inserted in your PowerPoint presentation, create a macro to reduce all the images to the same size and position on the slide. Before you create the macro to automate the task, you may want to practice the steps on a single image to make sure you get the exact results you want.

  1. Go to View and select Macros.

  2. In the Macro dialog box, enter a Macro name.

    The name can contain letters and numbers, but must begin with a letter and cannot contain any spaces. Use the underscore to indicate a space in the macro name.

  3. The Macro in list displays the name of the presentation you're working on.

    A macro can be applied to several presentations. Open the other presentations and select All open presentations.

  4. Select Create to open Microsoft Visual Basic for Applications.

  5. Enter the following information but replace the numbers after the equal sign with your own desired image size and placement. Enter numbers in points.

    With ActiveWindow.Selection.ShapeRange
    .Height = 418.3
    .Width = 619.9
    .Left = 45
    .Top = 45
    End With
