So I have a bit ovwr 100 music tracka according to Windows Media Player and I want tgem on my phone, but none of the tracks are mp3 format. I ripped them from my friend's dad's old CDs and it said it was all legal and everything. I know I can use convertor websites but they do it one song at a time. :/

Is there any way to convert the songs in bulk?

What format are they in? What phone do you have? Most phones support more than just mp3 and many file types are superior. If you can get away with not changing, you'd be better off, as lossy->lossy almost always loses quality
