When you open Microsoft PowerPoint, slide thumbnails are displayed in the left pane by default. PowerPoint allows you to hide, show, or even resize these thumbnails. Here’s how.
Manage slide thumbnails
Everyone has their own style of work. Some may prefer to save slide thumbnails to create an outline, or to easily move between slides as changes are made. However, some may find them distracting or intrusive and as such would like to hide or reduce their size. Both are relatively easy to complete.
Go ahead and open PowerPoint. By default, you should be in PowerPoint’s «Normal» view mode. If not, go to the «View» tab and click the «Normal» button.
While in normal view, slide thumbnails will appear on the left side of the window.
To reduce the thumbnail size, click and drag the separator bar to the left.
The further to the left you drag the divider, the smaller the images shrink. To completely hide the thumbnails, drag the bar to the left until they disappear.
If you’ve hidden the thumbnails but need to show them again, click the arrow above «Thumbnails» on the left side.
