# Create page thumbnails

Because page thumbnails increase file size, they are not automatically created. After you create page thumbnails, you can embed them in the PDF. Embedding prevents the page thumbnails from redrawing each time you click the Pages button, often a time-consuming process. Embedded page thumbnails won’t reflect changes that you make to document pages until you unembed the page thumbnails.

### Create page thumbnails

Click the Pages button on the left.

Page thumbnails appear in the navigation pane. This process may require several seconds, particularly in larger documents. The drawing of page thumbnails may pause if you interact with the application during this process.

### Resize page thumbnails

In the Pages panel, choose Reduce Page Thumbnails or Enlarge Page Thumbnails from the Options menu.
