Split PowerPoint

1. 1

   Open a deck

   Drop in a .pptx, .pptm, .ppsx, .ppsm, .potx or .potm file. Every slide appears as a thumbnail.

2. 2

   Choose how to split

   Pick slides by clicking them, or switch to every slide, odd and even, every N slides, or by section.

3. 3

   Check the plan

   The rail shows how many files you will get and roughly how large they will be, before anything runs.

4. 4

   Download

   One part downloads as a presentation; several download together as a single ZIP.

Extract only the slides you need into a focused deck, or break one presentation into many at once. Every slide is drawn as a thumbnail you can click, so choosing is a matter of looking rather than remembering slide numbers, and five split modes cover the jobs people actually bring a splitter: pull out a section for a client, send one file per slide to a reviewer, produce a handout of every other slide, or cut a long deck into chapters.

• Thumbnail selection: every slide is rendered and clickable, and the range box stays in step with the grid.
• Five split modes: selection, every slide, odd and even, every N slides, and one file per PowerPoint section.
• A plan before the work: how many files and roughly how large, shown before you press anything.
• One ZIP: several parts arrive as a single download rather than a queue of them.
• Smaller parts: pictures and notes that the kept slides do not use are left behind.
• Nothing leaves the device: no upload, no queue, no retention window.

A presentation is not a list of slides. It is a package: the slides, the layouts they sit on, the masters those layouts sit on, a theme, fonts, pictures, charts, embedded workbooks, speaker notes, comments and a set of cross-references tying it all together. A split has to decide which of that travels, and getting it wrong is invisible in the file browser and obvious the moment PowerPoint opens the result.

The rule here is reachability. Starting from the slides you kept, the tool follows every relationship out — this slide uses that layout, that layout uses this master, this master uses that theme, this slide references those three pictures and that notes page — and carries exactly what it reaches. Anything nothing points at stays behind. That is why a part is smaller than the deck rather than the same size: on a 60-slide presentation whose 14 MB is almost all photographs, extracting three slides carries three photographs, not sixty.

• Kept: the slides you chose, their speaker notes, their layouts and masters, the theme, embedded fonts, charts, tables, embedded workbooks, comments and every picture those slides use.
• Kept, at full fidelity: the bytes of every picture and media file, copied across without being decoded or re-encoded, so nothing loses quality on the way through.
• Dropped: notes pages, pictures, layouts and masters that only belonged to slides you removed.
• Repaired: links to a removed slide, custom shows, and PowerPoint sections that named slides which are no longer there.

One deck, five different questions. The mode picker sits at the top of the settings rail, and the thumbnail grid shows which slides each mode will keep as soon as you choose it.

Keep the slides I choose

The default. Click any thumbnail to add or remove it, or type a range such as 1-5, 7, 10-12 into the range box. The two stay in step: clicking updates the text, typing updates the grid. A range that runs past the end of the deck is clamped rather than rejected, and a slide number that does not exist is called out instead of quietly selecting nothing. Everything you keep goes into one new presentation, in the deck's own order.

Every slide as its own file

The most common reason people search for a PowerPoint splitter. Each slide becomes a complete, self-contained presentation carrying its own notes, layout, master and pictures — named after its slide number, so slide 7 becomes deck_slide7.pptx. All of them arrive as one ZIP.

Odd and even slides

Two files: slides 1, 3, 5, and slides 2, 4, 6. The counting is one-based, the way the slide numbers read on screen. Useful for decks built as pairs — a question slide and its answer, a before and an after, an English slide followed by its translation.

Every N slides

Cut the deck into equal chunks: five slides per file, ten per file, whatever the number is. The last part keeps the remainder rather than being padded or dropped, and the control cannot be set past the length of the deck — a value it cannot honour is a value it does not offer.

One file per section

PowerPoint lets you group slides into named sections, and almost nobody's splitter can read them. This one can: if the deck has sections, each becomes a file named after it, and the grouping is the one the deck's own author already made rather than one you have to reconstruct from slide numbers. Two sections sharing a name do not collide in the ZIP. The mode is offered only when the deck actually has sections, rather than sitting there as a control that accepts a click and does nothing.

Choosing slides by number means holding the deck in your head. The competing online splitters all ask you to: two of them show no preview at all, and the third shows a text list. This one draws every slide.

The thumbnails are rendered on your device from the deck's own markup — backgrounds, pictures, shape geometry, tables, connectors and text, with the real inheritance chain, so a title placeholder that takes its position from the layout and its size from the master appears where and how PowerPoint would put it. They are a way to choose, not a substitute for PowerPoint: animations, transitions and chart plotting are not drawn, and a chart or a diagram appears as a labelled box rather than as an approximation that might look convincing and be wrong. The whole grid of a 60-slide deck is drawn in well under a second, which is what makes selecting by eye practical at all.

This is the part that separates a splitter that produces a working file from one that produces a file PowerPoint offers to repair. A deck refers to its slides by identity in at least four places, and each of them has to be brought into line with what survived.

• Slide-to-slide links: a "back to the agenda" button pointing at a slide you removed. The link is emptied and the action removed; the shape, its text and its animation stay.
• Custom shows: a named subset of the deck. It loses the slides that went, and a show left with none is removed rather than kept as an empty entry in the show list.
• Sections: trimmed to the slides that survived, and an emptied section is removed instead of appearing as a real, named, empty section in the section pane.
• Notes pages: each notes page points back at the slide it belongs to, so the pairing survives even when the slides you kept were scattered through the deck.
• Document properties: the slide count and the list of slide titles are rebuilt, so the file does not report sixty slides while holding three.

Six file extensions, one package format. The file dialog accepts exactly those six and nothing else, so you cannot pick a file, wait, and then be told it will not open.

PPTX, PPSX and POTX

The ordinary presentation, the slideshow and the template. All three are the same package with a different label on the main part, so all three split identically. Slideshows and templates come out as ordinary .pptx presentations, because a split of a template is something you present rather than something you start a new deck from.

PPTM, PPSM and POTM

The macro-enabled family. These split the same way and stay macro-enabled: the output is a .pptm, because the project the macros live in is only legal inside a package that declares itself macro-enabled. Renaming one to .pptx to look tidier would produce a file PowerPoint refuses.

PPT, ODP and Keynote

The old binary .ppt format, OpenDocument .odp and Apple's .key are different formats rather than variations on this one, and they are refused by name at the file dialog rather than accepted and failed later. To split one, open it in PowerPoint, Google Slides or Keynote and save it as .pptx first — the conversion is something those applications do properly and a browser tool would only approximate.

A presentation is a ZIP archive, and its pictures are already compressed — a JPEG inside a .pptx is a JPEG that has been deflated at a ratio close to 1.0. Most tools that split one decompress every part, keep some, and compress them all again, which spends the entire cost of the operation arriving back where it started.

This one copies those bytes straight across, still compressed. Nothing is decoded, so nothing can be lost and nothing has to be re-encoded, and the cost of a split tracks the archive's directory rather than its contents. The measured result on a 14 MB, 60-slide deck: three slides extracted in about a millisecond, or every slide turned into its own file — all sixty, plus the ZIP — in well under a tenth of a second. The same three-slide extract from a 71 MB deck takes the same time, because neither one ran a codec.

Runs on your device — the deck is read where it already is, and nothing is uploaded.

Everything that decides whether the output is correct is free. All five split modes, the thumbnail grid, section detection, notes and media handling, and the ZIP are included at no cost, because a split that quietly damages a file is not a feature worth charging for.

• Free: decks up to 50 MB and 500 slides, up to 50 parts per split, every mode, the full thumbnail grid and the ZIP.
• Pro: no size cap beyond what your device can handle, up to 2,000 parts, 20 decks queued, and custom naming for the parts and the ZIP.
• Both: it all runs on your device, not our servers.

• Merge PowerPoint
• Change Slide Size
• Extract Text from PPTX
• Compress PowerPoint
• PowerPoint Tools
• Measure what is left
