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

To try file merge operations, load two or more presentations. Click Upload File to add files one at a time. Supported formats are PPTX, PPTM, POTX, and POTM. Note that file upload order determines slide order in the merged file.

To merge all uploaded presentations and download the result, 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.
