PowerPoint Presentation Merger

An online tool for merging PowerPoint presentations: the slides of several files are combined into one .pptx in the order you set. Each part is carried over whole — with its own theme, layouts, charts and speaker notes, so nothing is redrawn and nothing shifts.

How to merge presentations

Add the files

Drop two or more .pptx presentations — you can also add them one at a time.

Put them in order

Use "Move up" and "Move down" to set which part comes first.

Get one combined .pptx

Click "Merge and download" — you get a single .pptx file.

Combine several presentations into one .pptx file

Drop two or more presentations

.pptx, .ppsx or .potx files

What you get

Each part keeps its design

Slides move with their own masters and themes: colors, fonts and backgrounds stay as they were in the source file.

No slide rebuilding

The file parts move as they are — charts stay editable with their Excel data, and SmartArt stays a diagram.

Speaker notes

Each slide's notes travel with it, so Presenter View in PowerPoint works as before.

Order with arrows

Reorder files with "Move up" and "Move down," remove the extra one — the result follows the order shown.

Different slide sizes

If parts were made in 16:9 and 4:3, the other slides are fitted into the size of the first one — the page warns you first.

When it helps

Assemble one talk from parts made by different people.
Combine several speakers' decks into one conference show.
Add ready-made slides from an old file to a presentation.
Merge a course's lectures into one file.

Why here

Merging works on the file's parts, not by redrawing: PowerPoint opens the result without asking to repair it, and every slide looks the same as in its source presentation.

FAQ

Will each presentation keep its design?

Yes. Slides move together with their layouts, master and theme, so each part keeps its colors, fonts and backgrounds — even when the parts were made from different templates. In PowerPoint you'll see this under View → Slide Master: there will be several masters.

Will charts stay editable?

Yes. A chart moves together with its embedded Excel workbook: in PowerPoint you can open it and change the data and the chart type. The same goes for SmartArt diagrams and tables.

What if the presentations have different slide sizes?

Slides in 16:9 and 4:3 can't be combined without rebuilding — a file has one size. In that case the slides of the other parts are fitted into the first one's size with margins at the edges, and their design is carried over by reading the file: ordinary shapes, text, tables and charts stay, while rare effects (3D, recolored pictures) may be simplified. The page warns you before merging.

Can I take only some of the slides from a file?

For now a file is added whole. Extra slides are easy to delete in the merged presentation: in PowerPoint, select their thumbnails and press Delete.

How many files can I merge?

The limit is the device's memory: the parts are held in the browser until the file is built. A dozen ordinary presentations work on any computer; for very heavy files with video, merging two or three at a time is safer.
