Merge PowerPoint decks into one presentation

Combine slide decks into a single .pptx while themes, layouts, speaker notes and media travel along. Each deck is imported as its own set of slides, so nothing overwrites anything.

Why use Mergevanta to merge slides

Every slide, in order

All slides from all decks are appended in the order you choose, with slide IDs and relationships rebuilt to stay valid.

Speaker notes included

Notes, layouts, masters and embedded media are copied with each deck, so the merged file presents exactly as designed.

Themes kept per deck

Each imported deck brings its own theme and slide layouts, so slides look the way their author intended.

Size mismatch warning

If decks use different aspect ratios, Mergevanta keeps the first deck's canvas and tells you so you can adjust in one click.

FAQ

Merge Slides questions

Both old and new PowerPoint files: .ppt and .pps (PowerPoint 97–2003) plus .pptx, .pptm, .ppsx and .potx. Old .ppt decks are converted automatically, so you can mix them in one merge.

Speaker notes, layouts and embedded media are carried over. Complex animation timelines are preserved where the source supports them.

The merged deck keeps the first file's slide size. Mergevanta warns you when it detects a mismatch so you can resize slides in PowerPoint afterwards.

Embedded media parts are copied across. Very large media can slow the merge: decks over about 4 MB in total are merged in your browser, so they depend on your device's memory.

Yes. There is no sign-up, no watermark on your slides and no limit on how many decks you combine.
