Yes, it removes the lines that are commented out and removes white space.

It first removes \r and \n. Then replace all other control characters,Tabs and spaces also.
It removes all single line and multi-line comments (// and /*/)
Also replaces all kind of spaces with single space.
All runs of line feeds are replaced with single linefeed.
Also replace variable name like it will replace long variable name to very short name(E.g,var declarevariable; to very simple var a;)
Thus it reduces size and helps to increase performance.
