## FAQ

### Does viewing a presentation require Microsoft PowerPoint?

No. The presentation is rendered by the library, so it can be displayed by an application or a web service with no Office installed.

### How do I show a presentation in a browser?

Render slides to images or export the deck to HTML, and serve that. Both routes avoid handing the original file to the browser, which also keeps the source deck private.

### Can I control the resolution of a rendered slide?

Yes. Slides are rendered at a scale you choose, so the same deck can produce small thumbnails and full-size previews.

### Which formats can be opened for viewing?

The PowerPoint formats and OpenDocument ODP, so a viewer built on this does not need to care which of them arrives.
