Okdo PowerPoint Merger

Being able to join multiple PowerPoint presentations quickly can be very useful when several team members are tasked with separate aspects of a project, and the end results need to be combined. To avoid having to transfer the slides manually, you can try Okdo PowerPoint Merger.
It is an easy-to-use application that allows you to join presentations saved to the older and newer Microsoft PowerPoint formats, provided the latter is installed on your computer.
However, it is not possible to modify the layout of the output file, as you can only choose whether or not the formatting for each source presentation should be preserved.

Supports multiple file formats

If the presentations you need to merge are saved to more than one format, you can load and process them all at the same time. They can be exported to PPT, PPTX, PPTM, PPS, PPSX or PPSM.
As a result, is is not necessary to convert your presentations to the same format manually, as the application can perform this task for you.

Minimalistic and intuitive interface

While such a simple application could not be expected to feature a complex interface, the available functions are well organized and easy-to-access.
Okdo PowerPoint Merger also offers support for drag and drop actions, greatly simplifying the task of importing new content.

Lacks advanced features

The program performs its intended function well, but the inability to customize the output file's layout reduces its usefulness. You cannot, for example, alter slide dimensions, change their orientation or choose which of them should be merged.
The application can preserve each file's original formatting, but this can be an issue when joining presentations with different layouts.
All in all, Okdo PowerPoint Merger is a simple software utility, designed to help you combine multiple PowerPoint presentations. It is easy-to-use but does not allow you to customize the output file's layout.
