This extension does not collect, transmit, or store any presentation data outside your machine. All screenshot capture, image processing, and PDF generation happen locally in your browser. No analytics, no external requests, no tracking.



Does it work with any Reveal.js presentation?
Yes — it detects standard Reveal.js slide/fragment navigation, whether the deck is hosted online or opened locally.

Will it capture slide transitions or animations?
No — the configurable capture delay lets you wait until animations/transitions finish before the screenshot is taken.

Can I use it on multiple tabs at once?
Yes — capturing can be enabled or disabled independently per tab.

Does it modify my presentation?
No — it works entirely from the browser side; nothing needs to be added to your Reveal.js project.
