How to combine PowerPoint presentations

  1. Choose two or more presentations.
  2. Put them in order with the arrows.
  3. Merge and download the new presentation.

How it works

  • The first presentation is the base: its slide size, settings and slides come first.
  • Slides from the others are added after it with their own slide masters, layouts and themes, so they look the way they did (PowerPoint calls this "keep source formatting").
  • Speaker notes, charts, SmartArt, pictures, videos, links between slides and table styles come along. If the first presentation has sections, each added presentation gets its own section.
  • Not copied: comments on the added presentations, their sections, custom slide shows, embedded fonts and macros.
  • If a presentation has a different slide size, its slides keep their positions; PowerPoint's Design › Slide Size can scale them.

The file is read and changed in your browser. Nothing is uploaded, and this site's security policy blocks the page from sending files anywhere.

Frequently asked questions

Can the added slides use the first presentation's design?

Not here: every slide keeps its own design. In PowerPoint, choose a layout from the first presentation's master for each slide if you want them to match.

Can I use an old .ppt file?

No. The old PowerPoint 97–2003 format (.ppt) is a different kind of file. Open it in PowerPoint, Keynote, Google Slides or LibreOffice Impress, save it as .pptx, then use that file. To just look at a .ppt, use the PowerPoint Viewer.

Is there a size limit?

No server-imposed file size limits. Very large presentations need more memory and time on your device; a computer copes better than a phone.

Is my presentations uploaded?

No. Everything happens in your browser, on your device.
