PowerPoint to Markdown
Convert .pptx decks to Markdown locally — one section per slide, notes included.
MarkPrep unzips your .pptx and reads the slide XML in your browser, turning each slide into a Markdown section with its title, bullets and speaker notes. Nothing is uploaded. The token count and chunk view then tell you how the deck will land in your model.
How to convert powerpoint to markdown
- 1Drop your PowerPoint deck onto the box above, or click to browse. Nothing uploads — the file is read in your browser.
- 2MarkPrep converts it to Markdown locally and shows a live token count for your chosen model.
- 3Check the Preview, adjust the chunk size, and review the Verify tab for anything worth a second look.
- 4Copy the Markdown, download the .md/.zip, or export JSONL chunks for your RAG pipeline.
Format notes & gotchas
- Text is extracted in reading order; complex slide layouts are linearised.
- Images and SmartArt are not transcribed — only text runs and notes.
- Speaker notes appear as blockquotes under each slide.

Frequently asked questions
Is my file uploaded anywhere?+
No. Conversion runs entirely in your browser tab using WebAssembly. There is no upload endpoint — open your browser's Network tab and watch: nothing leaves the page. The only labelled exceptions are fetching a public URL and optional bring-your-own-key OCR.
How much does it cost?+
Conversion and the entire AI-Ready Pack — token counts, chunking, JSONL export — are free and unlimited, because they run on your hardware. Pro ($4/mo) adds workflow features like the local MCP server, watch folders and saved profiles.
Are the token counts accurate?+
Exact for OpenAI models (GPT-4o, o-series) via their published tokenizer. For Claude and Gemini we show a labelled approximation, because those tokenizers aren't public.
Want it inside your workflow?
Conversion is free forever. Pro ($4/mo) adds the local MCP server so Claude Code converts files on your machine, plus watch folders, saved profiles and encrypted sync.
