Convert HTML to `.stage` in SlideStage Lite

Mirrored docs keep the language used by their source repo. Site chrome stays in your selected language.

This tutorial shows how to use the SlideStage Lite browser converter to turn an HTML deck into a .stage file.

Conversion happens locally in the browser. Source files are not uploaded.

1. Open the converter

Open SlideStage Lite and choose the HTML deck converter.

It accepts:

  • A single .html file.
  • A folder with an entry HTML file.
  • A .zip containing an HTML deck.
  • An existing .stage file.

2. Choose the source

For multi-file decks, choose the folder or zip instead of only the entry HTML. This lets the converter include assets such as images, CSS, fonts, and scripts.

3. Pick a mode

Use auto unless you know the tradeoff.

  • split: one output HTML file per slide.
  • wrap: preserve the original deck runtime.
  • single: plain HTML as one slide.
  • passthrough: validate and re-emit an existing .stage.

Use wrap for reveal.js and impress.js when you need their runtime features.

4. Review capabilities

If scripts survive conversion, the manifest may include compat.requires. Lite will ask for consent during playback.

5. Download and verify

Download the generated .stage, then open it in Lite immediately.

Check slide order, assets, notes, and trust prompts.

Troubleshooting

If folder upload is unavailable, zip the folder and upload the zip.

If reveal animations disappear, use wrap mode.

If offline assets are missing, run the mirror pass.
