If you want to upload them to Wikimedia Commons, usually the best alternative is to save your presentation as a PDF. Please add the category for space you are presenting in, what day you are presenting and, of course, that it is a presentation.

I thank you for your efforts. I have prepared PPTX Presentation slides for Wikimania 2019. I ask about how to upload them to Wikimania wiki.

Thank you for sharing your slides' sources. Please save them in ODP format (e.g. by using LibreOffice) and upload them on... ahem. I guess archive.org would be a good place, we already keep many Wikimania videos there.

On WMF wikis, these formats are currently only allowed on private wikis.

Federico
