I want to change my profile pic but i dont want everyone to see i changed it. so how do i change it without anyone finding out

by default the profile pic is always set to public.
but still ,you can
first change your profile picture and then Quickly go to your timeline and you can see your post of changing your profile picture .
see in the post there is written remove option then you can delete the post or remove it.

The profile picture is set to public.
Yeah, you can delete the post that says that : XYZ has changed his profile picture
But people will notice that you've changed it.
So there's nothing much you can do about this.

The Only Way is to Change the Privacy Setting of the Profile Picture After you Upload it
