How to Merge PowerPoint Presentations

How to Merge PowerPoint Presentations

It is difficult for two or more people to work on PowerPoint presentations simultaneously, because Office does not have the same collaboration features offered by Google Slides. One way to overcome this problem is to combine PowerPoint presentations into one file.

Combining two PowerPoints can be done by importing slides using the “Reuse Slides” option or by using the copy and paste method. These instructions are designed to work for the latest versions of Office, including Office 2016 and 2019, as well as Office 365 and Online. You might find different instructions for earlier versions of PowerPoint.

Merge PowerPoint Files Using the Reuse Slides Option

The “best” method for combining PowerPoint files, or at least the method officially supported by PowerPoint, is to use the “Reuse Slides” option. This feature shifts content from one presentation file to another, according to the theme of the new presentation file in the process.

To do this, open your PowerPoint presentation file – this is the file that you want to merge. On the “Home” tab on the ribbon bar, select the “New Slide” button and then click the “Reuse Slides” option at the bottom of the drop-down menu that appears.


A menu will appear on the right. Click the “Browse” button to find the PowerPoint presentation file that you want to join to your open file.


Find your second PowerPoint file and then click the “Open” button to enter it.


A list of slides from your second presentation will appear in the “Reuse Slides” menu on the right.

First, you must decide on the formatting for the inserted slide. If you want to keep the format (including themes) of the original presentation, make sure that the “Keep Source Formatting” checkbox is activated at the bottom of the “Reuse Slides” menu. If you don’t check, the slide you enter will have an open presentation style applied to it.


To insert individual slides, right-click the slide and then select the “Insert Slide” option. Otherwise, click “Insert All Slides” to copy all slides to your open PowerPoint presentation.


Your slide (or slide) will then be entered into the open presentation, directly below the slide that is currently selected. With your PowerPoint file merged, you can then save your merged file by clicking File> Save or Save As.

Copy and Paste PowerPoint Slides

While the “Reuse Slides” method allows you to change the format of your slides before you insert them, you can also merge PowerPoint files by copying slides from one open PowerPoint file and inserting them into another.

To do this, open a PowerPoint presentation and select the slide you want to copy from the slide selection menu on the left. From there, right-click on the selected slide and then press “Copy” to copy it to your clipboard.


Switch to your PowerPoint presentation looking to stick your slide inward and then, in the slide selection menu on the left, right click on the position you want to paste to your slide.

To paste the slides and apply the theme of the open presentation file to them, click the paste option “Use Destination Theme”.


To preserve the original theme and formatting, select the “Keep Source Formatting” paste option.


The slide you pasted will then appear in your new presentation at the position you selected. You can then save the merged file by clicking File> Save or Save As.
