Is this endgame scenario winnable for white? [title "White to move"]
[fen "8/8/4kr1Q/1p2pp2/1P1n4/p3K3/P7/8 w - - 0 1"]


I’m looking at this current position, and I think I'm going to lose, as I have limited mobility with both my king and queen. But a friend suggested otherwise, saying that I should put more focus on destabilizing the pawns up front, and therefore I have a high probability of winning otherwise.

Suggestions would be appreciated.
Looks rather lost (for white) to me.  Black basically has a fortress except for the a3 pawn.

If white wanted to win this (with black not doing anything), you'd have to win the a3 pawn, play a4 and promote a pawn. I don't think white has time for this as black's e,f-pawns will run very fast.

So the only realistic chance is a perpetual.
