Merge PowerPoint Presentations — Combine PPTX, PPT & ODP
Combine two or more presentations — .pptx, legacy .ppt, or OpenDocument .odp — into a single .pptx file right in your browser. Arrange your files in the order you want, then merge — every slide keeps its own design, images, notes, and transitions. No uploads, no sign-up, no PowerPoint required.
Why merge with AnyDocFlow
One-click merge
Combine multiple PowerPoint files into a single deck in seconds. The slide order follows the order of your files — nothing to configure.
Reorder before merging
Arrange your files into the exact sequence you want before combining — use the up and down arrows to reorder the list.
Design preserved
Each slide keeps its own layout, master, theme, fonts, and colors, so the merged deck looks exactly like the originals — no restyling.
Media, notes & transitions kept
Images, speaker notes, charts, transitions, and embedded objects travel with their slides into the merged file.
100% private
Merging happens entirely in your browser. Your presentations never leave your device — nothing is uploaded to a server.
Free & no sign-up
No account, no watermark, no limits. Merge as many presentations as you need, whenever you need to.
Merge PowerPoint files made effortless
Combining presentations is one of the most common tasks when you collaborate on slide decks — pulling together chapters written by different teammates, adding an appendix, or assembling a final pitch from several source files. AnyDocFlow merges your presentations directly in your browser: add .pptx, .ppt, or .odp files, arrange them in the order you want, and get a single combined .pptx that opens cleanly in PowerPoint, LibreOffice, or Google Slides. Non-pptx inputs are converted to .pptx first by an in-browser office engine, so mixed teams working in different tools can still hand you one clean deck. Every slide keeps its own design, images, notes, and transitions. Fast, free, and 100% private — your files never leave your device. Need the reverse? Use the PPT splitter to divide a presentation into separate decks.

Good to know
Inputs can be .pptx, legacy .ppt, or OpenDocument .odp — .ppt and .odp files are converted to .pptx first. That conversion needs cross-origin isolation (COOP/COEP), which works on https:// or http://localhost; if you opened this page via a LAN IP or plain http, a hard refresh (Cmd/Ctrl + Shift + R) may be required. The merged file is always saved as .pptx. Files are combined in list order; the first file provides the base package while every other slide keeps its own original design. Speaker notes, images, charts, and transitions are preserved. Files of any size are accepted, and everything runs locally in your browser.
