Add slide presentations to your website
You can add slide presentations to your website in a number of different ways.
Let others download your original file
Upload your presentation document to the website just like any other document and let people download it. This is the easiest option for you but relies on the person taking the effort to download and open the document on appropriate presentation software.
Upload your presentation to a hosting service
There are a range of services such as SlideShare, iSpring Cloud and various others will host your slides on the web and provide you with an embed code so that people can click through the presentation without leaving your website or downloading anything.
