AAC (Advanced Audio Coding)
A modern audio format that delivers better sound quality than MP3 at the same file size. The default format for Apple Music, YouTube, and most streaming services.
MP3 (MPEG Audio Layer III)
The universal audio format. Plays on every device and app imaginable. Uses lossy compression to keep files small while maintaining good sound quality.
AAC sounds great but not every device supports it natively. Converting AAC to MP3 gives you the most compatible audio format in existence โ MP3 plays on literally everything, from vintage MP3 players to the newest smartphones.
At the same bitrate, AAC is slightly better. But the difference is minimal and MP3's universal compatibility often makes it the more practical choice.
There's a tiny quality reduction when converting between lossy formats, but it's virtually unnoticeable in normal listening.
