AAC is the successor to MP3, used by YouTube, streaming services and most modern devices. It delivers better sound than MP3 at the same file size. MP3 is the most universally compatible audio format. It uses lossy compression to make small files that play on virtually any device, app or website. Both formats are compressed; converting re-encodes the audio to MP3 for better compatibility and a comparable file size.
