When splitting a presentation makes sense
Large decks built for internal review often contain sections that were never meant to be shared externally — an appendix, a financial model, internal talking points. Splitting lets you hand off only the slides that belong in a given context, without opening the full deck in a presentation app and manually copy-pasting slides.
The tool works by opening the PPTX (which is a ZIP of XML files), removing slides outside your chosen range, renumbering the remaining slides to be sequential, and updating the internal relationship tables so the output opens cleanly. Themes, fonts, and media embedded in the original are carried over untouched.
If you need to extract every slide as a standalone file — for use as individual assets or for thumbnail generation — switch to "Individual slides" mode and download the resulting ZIP.
Frequently asked questions
Are my files uploaded when I split a presentation?
No. The split runs entirely in your browser. Your PPTX is read directly from disk, processed with JSZip, and the resulting files are offered as downloads — nothing is sent to a server.
What does "individual slides" mode produce?
Each slide is extracted into its own PPTX file. Because multiple files result, they are packaged together in a ZIP archive for download. The file names follow the pattern slides-1.pptx, slides-2.pptx, and so on.
How do I specify custom ranges?
Enter comma-separated ranges in the text field. Each range can be a single slide number (e.g. 5) or a start-end pair (e.g. 3-7). Each range produces a separate PPTX. Example: "1-5, 8, 10-12" produces three output files.
Are slide masters and themes preserved in the output files?
Yes. Because the split works by removing slides from a copy of the original ZIP rather than reconstructing the file from scratch, the slide masters, layouts, themes, and media from the original deck remain intact in each output file.
What happens to speaker notes when splitting?
Speaker notes attached to kept slides are preserved. Notes belonging to removed slides are cleaned up: their notesSlide XML files are deleted and their content-type overrides are removed so the output file does not trigger a repair prompt when opened.
