Using a converstion software, most of which can be found for free online. I recommend the "Converstion Lite" software as it is free and very user friendly/versatile, but be careful to read through the fine print as you download the software. The company will ask you to agree to its terms of uses (no problem there), but will ask you to agree (in separate windows) to download other software. I DO NOT recommend this!
