About this tool

PDF Slideshow turns any PDF into a presentation right in your browser. Go full screen, move with the arrow keys, Space, a presentation clicker or a swipe, and choose a fade or slide transition between pages. A built-in laser pointer highlights what you're talking about.

“Export 16:9 deck” creates a new PDF in which every page is centred on a widescreen 16:9 slide with a black background — perfect for projectors and TVs when your PDF is A4 or Letter. The pages stay vector, so text remains sharp.

Nothing is installed and nothing is uploaded: open the page, drop the PDF and present, even offline.
