MergePptx Demo
MergePPtx is for concatenating pptx presentations together.
It is part of Plutext's commercial Docx4j Enterprise Edition.
It can use the slide masters and layouts from the first presentation,
to "re-brand" subsequent presentations to have the same look and feel. That is shown in this demo. Alternatively, the actual product can
be set to retain the distinct look and feel of the original slides, but that is not demo'd here.
With MergePptx, it is possible to select specific slides (eg slide 5, and 14-22) from a presentation. But this simple online demo just uses the whole of each presentation.
To try it out, select up to 6 pptx files to merge together:-
