IPYNB to Reveal.js Converter
Processing entirely on your device — large files may take a moment.
Jupyter Notebook and Reveal.js HTML Slides exist for different jobs: IPYNB is the Jupyter Notebook format: a JSON document mixing markdown cells, code cells, outputs and metadata. It is the default medium of data-science work — every analysis, tutorial and Kaggle kernel lives in one. 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 IPYNB format
The Jupyter Notebook (.ipynb) is the working document of data science: a JSON array mixing markdown cells for narrative, code cells for Python/R/Julia, and their captured outputs — tables, charts, errors. Every Kaggle kernel, tutorial and analysis memo is one.
Notebooks are awkward to read outside Jupyter, and impossible to hand to management as-is. Converting to Markdown/Word/HTML turns the narrative plus results into a shareable report — or turns a written report into a ready-to-fill notebook skeleton.
+Strengths
- ✓Narrative + code + outputs in one artifact
- ✓The lingua franca of data-science workflows
- ✓Executables — results can be reproduced
!Limitations
- −JSON is unreadable without Jupyter
- −Outputs bloat files and leak secrets
- −Merge conflicts are notoriously painful
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.
+Strengths
- ✓One file, runs in any browser
- ✓Speaker notes, fragments and PDF export built in
- ✓Editable as plain HTML afterwards
!Limitations
- −Needs internet for the CDN runtime
- −Design is template-driven, less bespoke than PPTX
- −Complex diagrams need hand-written HTML
Why convert IPYNB to Reveal.js?
Converting makes sense where the strengths of Reveal.js meet what IPYNB cannot give you. One file, runs in any browser Meanwhile JSON is unreadable without Jupyter One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this IPYNB 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.

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 IPYNB 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 IPYNB file be preserved exactly?
This converter renders your IPYNB 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.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
