Turn Markdown into slides
A presentation that is one file: mail it, put it on a USB stick, open it on the podium machine, press F. Nothing to install and no service that can be down.

How it works
- Write the Markdown; --- on its own line starts a new slide; note: lines become speaker notes.
- Pick theme and accent, build, and check the preview.
- Download the HTML — that file is the presentation.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
How do speaker notes work?
Press S during the presentation: a second window opens with your notes, the slide number and a running timer. Put it on your laptop screen while the projector shows the deck. Notes never appear on the main screen.
Can I get a PDF?
Print the presentation file from the browser — each slide becomes one page. That PDF is the handout version; the HTML remains the one with navigation and notes.
Why not just use PowerPoint?
For text-driven talks, Markdown is faster to write and version-controls cleanly. When you need heavy layout, animation or a corporate template, PowerPoint is the right tool — this is for the deck you want finished in twenty minutes.
