Open this converter, upload your.ipynb, and download the generated.html. Open the file in any browser to present. The deck uses Reveal.js so the experience matches the standard nbconvert --to slides output.

Yes. Cells tagged with slide, subslide, fragment, skip, or notes in cell.metadata.slideshow render the same way RISE and nbconvert --to slides render them.

The converter falls back to splitting on top-level Markdown headings. A well-structured notebook becomes a usable deck without you having to tag every cell first.

Either re-tag the cells in JupyterLab’s slide editor and re-run the converter, or open the downloaded.html in a text editor and rearrange the <section> tags directly. The format is plain HTML.

The default version pulls Reveal.js and Highlight.js from a CDN, so it needs the network the first time you load it. Browsers cache these assets, so re-opening offline usually still works. For fully offline talks, save the page with its assets via your browser’s Save Page As option.

Open the.html, append ?print-pdf to the URL, and use your browser’s Print to Save as PDF. This is the standard Reveal.js export route and produces one PDF page per slide.

Yes. Image outputs stored inside the notebook (matplotlib PNG, etc.) appear inline on the slides when Include outputs is on.

Yes. Press S in the presenter view to open Reveal.js’s speaker window. Cells tagged as notes show up there alongside the current and next slide.

It produces the same kind of Reveal.js HTML deck and respects the same metadata. The differences: no Python install, no LaTeX dependency, single-file output, and conversion in the browser.

Secure server conversion — processed briefly, not stored afterward. The downloaded .html is what you keep and share.

Yes. The converter ships with a light and a dark theme. For more theming, edit the inline <style> block at the top of the downloaded.html or replace the theme stylesheet link with another Reveal.js theme.

Static outputs (PNG snapshots, HTML widgets that store their data in the notebook) appear on the slides. Live, kernel-backed widgets do not run because the deck is static; for live demos use RISE in JupyterLab.

Yes. Structure the notebook with clear Markdown headings or slideshow tags, export, and present. Students can receive the .html even if they never install Jupyter.

Cells tagged fragment or subslide follow Reveal.js / nbconvert conventions: fragments appear step-by-step; subslides nest under a parent slide. Tag in JupyterLab’s slide tools, then re-export.
