WMA (Windows Media Audio) is Microsoft's music format for Windows Media Player, and a Mac does not play it: the Music app, QuickTime Player, and GarageBand will not open WMA files. MP3 is the widely supported format that plays on any phone, car player, and in the Music app.

To MP3 Converter turns whole folders of WMA files into MP3s in one drag and drop. Music bought or ripped on a Windows PC then plays in the Music app, on your iPhone, and in the car. The tags and album covers are kept, and automatic settings guarantee the best sound quality.


Convert WMA to MP3
