Use any good graphics editor (getpaint.net will do) and go to the Image menu and opt to Resize. Be sure any box that says to ';Keep aspect ratio'; is checked. What ever the width size is shown, reduce it to 1/4 of value. Change back by pressing Ctrl + Z and try again if too small or not right.



You could use this free online graphics editor to do the same:
