Why convert AAC to MP3?

AAC is the successor to MP3, offering better sound quality at the same bitrate. It's the default format for iTunes, YouTube, and most streaming services — a sweet spot between size and fidelity. MP3 is the most popular audio format in the world. It uses lossy compression to deliver small file sizes with reasonable quality, and works on virtually every device, app and platform ever made. Converting from AAC to MP3 is useful when you need music playback on every device or want to take advantage of universal support on every platform.

Top reasons to switch to MP3
