WebDecks vs OpenOffice Impress

OpenOffice Impress (and its livelier cousin LibreOffice Impress) is a free, full desktop presentation app — more featureful than WebDecks, but you have to download and install it. WebDecks is the option for when you'd rather not: open a browser tab, work on your .pptx, and move on.

Which should you use?

If you want a powerful, free, fully-featured desktop presentation app and don't mind installing one, Impress is a great choice.

If you can't or don't want to install software — a work laptop, a Chromebook, a borrowed machine — WebDecks lets you open and edit your .pptx in a tab and export a PDF, no setup required.

Honest note: WebDecks is newer and intentionally simpler. Impress has years of features WebDecks doesn't; we're betting that 'just open it in a tab' is worth more for quick, everyday edits.
