Combining team decks
Pull the strongest slides from each contributor’s file into one board-ready presentation, without reformatting every paste.
PPT Merger is a free online tool that combines multiple PPTX files into one presentation — pick the exact slides you need from each deck, merge them without losing formatting, and download the result. Everything runs locally in your browser.
PPTX only · Multiple files supported · Nothing is uploaded
How it works
Add two or more PowerPoint presentations you want to combine. The files stay on your device.
Use visual thumbnails to select pages, apply ranges and reorder source decks.
Generate one validated PPTX and open it in Microsoft PowerPoint for final review.

What goes in
Most PowerPoint mergers append one complete presentation after another. This one lets you inspect each source deck first, so unwanted title pages, appendices and duplicate slides never enter the final file.
1-5, 8, 11-14There is no two-file limit. Add as many decks as you need, drag them into the order you want, and combine multiple PowerPoints into one presentation in a single pass. Taking a handful from each instead? See how to merge slides from several decks.
No install, no account
PPT Merger is an online PowerPoint merger that runs in the browser you already have. There is nothing to download and no add-in to approve, so you can merge PPTX online from a work laptop, a borrowed machine or a locked-down desktop. Because the merge itself happens on your device, “online” describes how you reach the tool — not where your presentations go. If you need a single PDF at the end rather than an editable deck, see merging PowerPoint to PDF.
This PPTX merger is free to use. There is no account to create, no watermark on the output and no cap on how many decks you combine at once. Combine PPT files as often as you need, with the full slide-level control described above — not a trial that stops at two files. For how that differs from a general-purpose converter, see PPT Merger vs iLovePDF.
Browser-only processing
Your PPTX files are never uploaded. There is no upload API and no presentation storage — parsing, thumbnail generation and merging all run inside a Web Worker in your browser, so the file contents never leave your device.

No. Files are read and processed locally in your browser. There is no server endpoint for presentation contents.
Yes. After adding files, you can select all slides, click individual thumbnails, use Shift-click for ranges or enter a page expression such as 1-5, 8.
Yes. Two files is the most common case: add both .pptx decks, keep all slides or select the ones you want from each, then merge them into one presentation. The same workflow handles three, four or more files.
Add two or more .pptx files, review the slides as thumbnails, then pick the ones you want from each deck: all slides, individual slides or a range such as 1-5, 8. Reorder the decks if needed and click Merge to build one editable presentation without losing its original formatting.
The merge engine carries source themes, slide masters, layouts and media into the output. PowerPoint files can contain unusual extensions, so always perform a final visual review.
PowerPoint can reuse or copy slides, but you first open a destination deck and import slides from another file. Copied slides can inherit the destination styling unless Keep Source Formatting is selected. PPT Merger lets you review several source decks, choose slides, reorder the sources and create one output in a single browser workflow.
PPT Merger is purpose-built for PowerPoint files. It processes files locally in your browser and returns a native, editable .pptx while carrying over themes, masters, layouts and media. When comparing tools, check whether they accept PPTX directly, where processing happens and whether the output remains editable.
There is no app or APK to install: the tool runs in your web browser. The interface adapts to smaller screens, but it has not been fully tested across phones and large presentations may need more memory than a mobile device has. A laptop or desktop is recommended for the smoothest experience.
Yes. The tool runs entirely in your web browser, so you can join PowerPoint files on a machine that has no copy of Microsoft Office installed. You will still want PowerPoint, Keynote or LibreOffice to review the merged deck afterwards.
No. Mail merge fills one presentation with data from a source such as an Excel sheet. This tool does a different job: it combines several separate .pptx files into one presentation, letting you pick which slides from each deck to keep.
Standard .pptx files are supported. Legacy .ppt files and macro-enabled .pptm files are intentionally rejected.
Yes. The tool is free to use and does not require an account.
