Why convert WMA to MP3
WMA — Windows Media Audio — was Microsoft's answer to MP3 and dominated Windows machines years ago. Today it's a liability: most phones, browsers, and players won't touch it. Converting your WMA files to MP3 future-proofs them, making old music and recordings play on any device again. The whole process runs in your browser, so your files stay private.
