Mac/Web buils size?

Every time i build my game which has 6 levels, my build size for mac and web is over 200MB THIS IS HUGE. How do i decrease the size as im trying to upload it to my website but it keeps failing as the file size is as said. thanks for the help.

Look in the editor log after a build to see where the largest sizes are coming from, and optimize those assets. Also, static batching can potentially increase size a lot depending on how many objects you have, since it has to create a single huge mesh.
