Real fidelity, not screenshots

Votinova's engine rebuilds your slides in HTML: selectable text, shapes, transitions and animations — not static images.

2

Verified against an extensive corpus of real decks

The import engine is tested against an extensive corpus of real PowerPoint files with full round-trip, including text animations and slide transitions.

3

In the browser, on any screen

The result opens in any modern browser — computer, tablet or phone — with no plugins and no PowerPoint installed.

What if your audience could vote on those slides?

With a free account your converted deck becomes interactive: quizzes, polls and word clouds between slides, with the audience joining from their phones via QR.

Frequently asked questions

Is the PowerPoint to HTML5 conversion free?
Yes: upload the .pptx and view it as HTML5 in the browser for free, with no account and no watermark. The preview is temporary; a free account keeps the presentation.
Are transitions and animations preserved?
Yes: Votinova's import engine rebuilds the slides with transitions and animations faithful to the original, verified against an extensive corpus of real presentations.
Can I download the HTML file?
Yes: after converting you can download a self-contained ZIP with index.html, the player and the images — it opens in any browser with a double click, even offline. You can also view and present it online from the browser.
What are the file limits?
Format .pptx with files up to 300 MB and no slide limit. Your file is never published or shared: it is kept privately solely to improve the conversion engine, and the anonymous session expires after ~30 minutes.
