Why convert PowerPoint to Markdown?
A slide deck is a great way to present, but a terrible way to feed information to an AI assistant. The content is scattered across shapes and text boxes, and there's no clean way to copy it all out. Converting a PPTX to Markdown gathers the text from every slide into one readable document you can paste straight into Claude or ChatGPT — to summarise the deck, turn it into speaker notes, draft a follow-up email, or extract action items.
It's also useful for turning a presentation into an outline or written document: once the text is Markdown, it drops cleanly into Notion, a doc, or a repo, ready to be reworked into prose.
How it handles your deck
The converter reads the text from each slide and lays it out slide by slide, with a heading for each ("Slide 1", "Slide 2", and so on), so the flow of the presentation is preserved and you can see where each point came from. Titles, bullet text, and body text on each slide are collected in order.
Honest limits: a deck is visual, and some of that doesn't translate to text. Images, charts, diagrams, animations, and exact layout aren't carried across — only the text. Text that lives inside images (rather than real text boxes) can't be read. Speaker notes are not included. What you get is the spoken/written substance of the deck as clean text, which is exactly what an assistant needs.
Your deck never leaves this tab
Slide decks are usually works in progress — an unreleased pitch, an internal plan, a client draft. Pulling the text out of one shouldn't mean handing the whole thing to an outside service, and here it doesn't: every slide is read and converted on your own device, with nothing transmitted anywhere. You can confirm it the honest way — watch the Network tab as you convert, or go offline first. The proof page shows both.
How to use it
Drop your .pptx file into the box above and convert. The Markdown appears in a text area with a one-click Copy button, ready to paste into your assistant. Below it you'll find an estimated token count, one-click prompt buttons in your language, and a chunk splitter for long decks.
A practical workflow: from deck to summary
Here's the sequence I use when someone sends me a 40-slide deck I need to act on quickly. First, convert the PPTX here and copy the Markdown. Because each slide sits under its own heading, the assistant can reason about the deck's structure, not just a wall of text. Second, paste it into Claude or ChatGPT with a specific instruction rather than a vague one — "list the three decisions this deck is asking for, and the open questions under each" beats "summarise this." Third, if the deck is long enough to strain the context window, use the built-in chunk splitter to break it on slide boundaries and feed it in parts. The whole loop takes a couple of minutes and turns a presentation you'd otherwise have to sit through into something you can query.
One tip that noticeably improves results: before converting, make sure the important text on each slide is real text, not baked into an exported image. Designers often flatten a slide to a picture for visual polish, and that text becomes invisible to any text-based tool. If a converted slide comes back empty, that's almost always why — the fix is to keep the text as editable text boxes in the source deck.
Frequently asked questions
Does it keep the slides separate?
Yes. Each slide's text is placed under its own heading ("Slide 1", "Slide 2", …) so you can follow the deck's structure.
What about images, charts, and animations?
Only text is extracted. Visual elements — images, charts, diagrams, animations — and text baked into images aren't carried across.
Are speaker notes included?
No, only the on-slide text is converted in this version.
Is my presentation uploaded?
No. Everything runs in your browser; the file is never sent to a server. See the verify-it-yourself page.
