How do MP3 and WMAcompare? Here's everything you need to know to choose the right format — and how to convert between them.
MPEG Audio Layer III
MP3 is the most popular audio format in the world. It revolutionized digital music by compressing audio files to a fraction of their original size while maintaining good quality. Nearly every device and application supports MP3.

WMA is Microsoft's proprietary audio format. While it offered competitive quality in the early 2000s, it has largely been superseded by AAC and other formats. It's still encountered in legacy Windows media libraries.
