Processing stays in your browser. Slides remain native editable PowerPoint package parts; the tool does not rasterize or upload them.
How to use Merge & Split PPTX Files
- 1
Select Merge PPTX Files and add up to ten presentations, or select Split PPTX File and add one standard PPTX.

For splitting, choose Extract selected slides, Split by ranges or Every N slides and complete the controls for that method.
- 4
Check compatibility notices and resolve any slide-dimension mismatch before processing.
- 5
Enter the output filename, run the local merge or split and download the PPTX result; multiple split files are also available together as a ZIP.
Frequently asked questions
About Merge & Split PPTX Files
Presentation cleanup often requires package-level editing rather than visual conversion. Merge mode builds a deliberate sequence from slides selected across as many as ten decks; Split mode can extract a subset, honor explicit non-overlapping ranges or create equally sized groups from one source.
The implementation follows the Open Packaging Conventions relationship graph. When a slide moves, its relevant layout, master, theme, notes, media, chart, embedded workbook and hyperlink dependencies are remapped with collision-safe part names and content-type declarations. This keeps native slide objects available for later editing instead of replacing them with screenshots.
Some desktop-only behaviors cannot be certified in a browser. Mismatched slide dimensions are blocked instead of distorted, and detected ActiveX, OLE, SmartArt or animation content receives a compatibility notice. Package manipulation and preview rendering stay local, without executing macros or resolving external resources.
