When you go to distribute your build in Renpy, there is a web option. You click that and it brings up a few options. I always click playable in browswer and that will build out a web version. upload the zip and then in the page where you upload the game theres an option to make it playable.  If you need, my discord is TeharraRose and I'm always on and up for questions  (I will say I just started making these about a year ago now -- which is crazy for me to think about now -- so I'm still new myself. lol)
