You do not specify what kind of output file size you want, so yes, it will be ‘as it is’.
Having a .wav extension on your input DOES NOT mean your input is uncompressed Wave PCM. (Wave Can be compressed, in your case, you have OGG compression with a .wav extension.)

What do you expect / why are you doing this? The quality of your file will NOT get better, nor will the file size get significant down if you process it.

Concerning your lack of knowledge, the only thing you can accomplish is making things worse.
