How to covert unity scene file to flash/HTML5/WebGL/Unity3dFile

Hi,
I was facing some trouble while trying to upload a game to some game websites. I even tried looking up some online file convertors, but I couldn’t find any. My game is in a unity scene file, but the websites only accept flash, HTML5, WebGL, or Unity3dFile. Please help me.

Thanks

Scene files, prefabs, materials and most of the stuff you see in the project view are just source files in a format only Unity can read. They cant be used as such on any device and are pretty much useless outside Unity.

When you want to give your game for others to play you have to make a build
