Org to Reveal.js Converter
Processing entirely on your device — large files may take a moment.
Emacs Org mode and Reveal.js HTML Slides exist for different jobs: Org mode is the Emacs ecosystem's plain-text format for notes, TODO lists, authoring and literate programming — asterisk headings, TODO keywords, #+begin_src blocks. Everything lives in one future-proof text file. Convert Markdown or Word content into a Reveal.js deck when you need a talk that runs from any browser — no PowerPoint, no install.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the Org format
Org mode is the Emacs universe's answer to "what if everything was plain text": one .org file holds your outlines, TODO states with agendas, deadlines, tables and even runnable code blocks. Twenty years of personal knowledge management workflows are built on its asterisk-and-keyword syntax.
Its reach outside Emacs used to be the pain — now a converter bridges it. Markdown collaborators get .md, managers get .docx, readers get .epub, and LaTeX journals get .tex, all with the outline hierarchy intact. Bringing Markdown back into Org is equally one click.

About the Reveal.js format
Reveal.js turns a single HTML file into a full presentation: keyboard-navigable slides, transitions, speaker notes, fragments and even built-in PDF export. The converted file references the Reveal.js runtime from a CDN, so it runs in any browser — nothing to install, nothing to upload.
Headings become slide titles and sections become decks of slides; lists render as fragments you can step through. It is the fastest way from written content to a talk that works on any screen — and the file stays yours, editable in any text editor.

- ✓Speaker notes, fragments and PDF export built in

Frequently asked questions
Is this Org to Reveal.js converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for Org to Reveal.js?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the layout of my Org file be preserved exactly?
This converter renders your Org content into Reveal.js with pages, proportions and images kept as close to the original as the target format allows. Use the preview before downloading to confirm it looks the way you expect.
Can I edit the Reveal.js result afterwards?
That depends on the target: Reveal.js is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
