There are many situations where you may need to convert YouTube videos to MP3. The most common scenario is finding a piece of nice background music and wish to save it on your iPhone. But sadly, iPhone doesn't offer this service. So you may need some converters like those introduced in this guide to help. 

Note: Before starting, keep in mind that any attempts to use the audios extracted from YouTube videos for commercial purposes are against YouTube's terms of use. So don't try to use the extracted audio for non-personal use without the holder's permission. Though we have mentioned this point thousands of times, it's still necessary to claim again here.

 If you prefer this program, just download it on your computer and follow these steps to convert videos to MP3.
