This demo uses the DevExpress Presentation API Library to merge slides from multiple presentations to a single PPTX file.

To evaluate file merge operations, load two or more PPTX files (click Upload File to add presentations one at a time). Note: Upload order determines slide order in the merged file. Once you upload all files, click Merge Presentations and Download.

In addition to slides and associated content, our Presentation API Library can also merge layout presets from each uploaded file.
