Files are merged in the order they appear in the list. The theme and layout of the first file will be prioritized.
Merge PowerPoint
Consolidate separate presentations into a single master deck. Perfect for assembling group projects, combining monthly updates, or organizing scattered slide segments. Our merger preserves the formatting, transitions, and media of each source file, ensuring a seamless transition between merged sections. Slides are appended in the order you arrange them, and each slide keeps its own design, images, charts, and animations. Where two decks define different themes, the first file's theme becomes the master while the remaining slides carry their original styling, so nothing is silently restyled. Speaker notes and embedded media travel with their slides, and the result is a standard PPTX you can keep editing. All merging happens privately in your browser, with no file ever uploaded. Nothing is compressed or re-encoded during the process, so image and chart quality stays exactly as authored.

Questions People Ask
Honest answers about how this works.
Will it mess up my slide masters?
The tool attempts to preserve the unique theme and master of each section, though some global theme synchronization may occur.
Do animations and transitions survive the merge?
Yes. Slides are moved between files with their animation timelines and transitions intact, and embedded media keeps playing. The only changes come from theme resolution when decks disagree on styling, which affects appearance rather than behavior, and your animations still run as authored.
Are my files uploaded to be merged?
No. Every presentation is opened, combined, and re-saved inside your browser. Strategy decks, financial reviews, and client material are processed locally, and the merged file is produced as a download without any server involvement, so nothing is stored remotely.
What happens to duplicate slide numbers or layouts?
Slide numbering follows the final combined order, so any fixed numbers from the original decks may need a quick update in PowerPoint. Layouts are matched by name, and where names collide the first deck's layout definition wins for new edits.
