ImageButton how to make the picture smaller?

I have a png file 500х500рх, a imageButton should be smaller but when I save it the picture is cropped. How do I make it so that the picture was the same size as the button, to crop a picture in photoshop is not an option as the large screen devices, the app will look awful
