What is AC3?
AC3 is an audio format. Converting it trades off file size, quality and compatibility to fit where the sound will be played.
What is MP3?
MP3 is the most universally compatible audio format ever made — lossy, small, and playable on absolutely everything. The safe default when you just need audio that works anywhere.
Why convert AC3 to MP3?
Most people convert AC3 to MP3 for compatibility — a website, app or device insists on MP3, and AC3 simply won't open. MP3 is widely supported, which makes it a dependable target. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
