Is there a preferred way to display powerpoint-like multimedia on a website?

I have a powerpoint file that contains several slides that I would love for visitors to be able to click through. I found a Squarespace page that discussed embedding Powerpoint files, and I tried that. I'm not a fan of the look of the embedding. These slides have gifs on them, and there's quite a few slides (I'm also considering breaking it up into maybe 4 smaller slide sets).  Is there a better way to display multimedia content (images, text, gifs) on a Squarespace website?  I've seen some sites that offer conversions from powerpoint to HTML, but I don't know if that would even be usage on my Squarespace website.
