Actually, what Beaverlicious posted is what you're looking for.
GameJolt will let you host your games for free (provided the game is also free to play) and they can download it in exe or zip format if you just want to give them the HTML folder in a zip (then they open the index file in Google Chrome).
As an added bonus, you'll even make some money from the adverts as people play or download your game (not much, but a few hundred plays might be a couple dollars).
Are you looking for somewhere to sell it?
