Counted with the browser's Performance API during the last job. It sees every request the page makes, but not what is inside them, so anything that is not a static download is counted above.

To check yourself: open DevTools → Network, clear the list, run the tool, and inspect each request. None will contain your file. You can also switch to offline after the page loads; tools whose engine is already downloaded keep working.

Count PowerPoint slides without opening the deck

Select a .pptx presentation and get its slide count in seconds, including hidden slides. Talk slots, printing quotes and submission rules often set a slide limit, so you can check the total before sharing or submitting a deck.

Counts every slide in the file

The file is opened as the ZIP package a .pptx really is, and the slide files inside are counted. The total includes hidden slides, because they are still part of the presentation. Nothing is rendered, so even large decks are counted quickly.

Download the result as JSON if you need to record it.

Hidden slides count

If your limit applies only to shown slides, subtract hidden ones. Only .pptx is supported; save .ppt, Keynote or Google Slides decks as .pptx first. For a PDF export of a deck, use PDF Page Counter.
