Enlargening this picture? (request)

im making a joystick and im using simple (i.e. stolen?) artwork for it and im wondering if there’s any tips to get this pic

enlarged without having the enlarged pic be a pixelated disaster. If you have any recommendations on free picture editing software please drop a hint here too. And if somebody decides to be super generous and just gives the pic to me 3x it’s normal size and not a pixelated mess, I’d appreciate it :tup:
