OpenSlides Markdown to PowerPoint
Markdown to PowerPointMarkdown to PowerPoint, free, in your browser.
Last updated 13 November 2026
Yes, you can convert Markdown to PowerPoint for free without installing anything. OpenSlides (openslides.dev) is open-source presentation software that runs in your browser: paste your Markdown or load a .md file, and every ## heading becomes a slide. The studio picks a layout for each one — a list of figures becomes a bar chart, a list of months a timeline — and File → Export PowerPoint downloads a .pptx whose headings and points are text boxes you can edit. No account, no watermark, and your Markdown is not uploaded.
Markdown to PowerPoint in five steps
- Open the studio and choose New deck, then Start from your notes, no structure.
- Paste your Markdown, or click Load a .md or .txt file. Start with a
#line for the deck’s title, and give each slide a##heading; you do not need---between slides. - Fill in What is it for? and click Plan it. You get one card per slide, each showing its type. Length starts at 8 slides and rises with your headings, up to 20; extra sections are listed with Add them back.
- Choose a look — Solstice, Editorial, Swiss or Aurora — and click Build the deck.
- Choose File → Export PowerPoint. The browser downloads a .pptx named after the deck. File → Export PDF gives one page per slide instead.
How your Markdown becomes slides
| In your Markdown | On the slide |
|---|---|
# Title | The deck’s title and its first slide |
## Heading | A new slide |
| Bullets | A list of points |
| A numbered list | A set of steps |
Bullets written as Label: number | A bar chart |
Bullets that start with a month, such as October: | A timeline |
A line starting with > | A quote; a second line such as > — The club handbook names the source |
A last section called Next steps | The closing slide |
The same Markdown gives the same plan every time, so the .md file can stay the source of the deck: edit it and build again when the content changes. Without an AI key, the outline comes from your headings and bullets; the rules are in your first deck needs no AI key.
What is inside the PowerPoint file
- Widescreen (16:9) slides.
- Headings and points are text boxes, not pictures, so they can be changed in PowerPoint.
- Charts, timelines and quotes are placed as pictures.
- Each slide keeps its speaker notes: the Markdown section it came from.
- Transitions between slides are kept. Effects on text and charts do not play, so each element shows its final state.
- Edits you make in the studio go into the file too.
What stays on your device
Planning, building and exporting happen in the browser tab. Your Markdown and the deck stay in the browser’s own storage and are not uploaded. The privacy policy lists the few requests that do leave the browser, such as AI you choose to connect.
FAQ
- Can I convert Markdown to PowerPoint for free?
Yes. Without AI, OpenSlides is free and needs no account. Build the deck from your Markdown and choose File → Export PowerPoint.
- Can I open a .md file instead of pasting?
Yes. Click Load a .md or .txt file when you start from your notes; the file’s text appears in the notes box, ready to plan.
- Is the PowerPoint editable?
The headings and points are text boxes you can edit. Charts, timelines and quotes come in as pictures.
- How many slides can one Markdown file make?
The Length setting goes up to 20. If your Markdown has more sections, the plan lists the extra ones, and Add them back puts them into the plan.
- Do animations carry over to PowerPoint?
No. Transitions between slides are kept, but effects on text and charts do not play. To show the motion, present from the studio or export a video.

No. It stays in your browser’s storage. Only AI you choose to connect receives the parts of the deck it needs.
