The Apple ecosystem standard

If you are trying to sync a high-resolution music library to an iPhone, iPad, or Apple Music, FLAC isn't going to cooperate out of the box. AAC is the native language of Apple devices. Making the switch ensures your library syncs perfectly without needing third-party media players.

Better sound at lower bitrates

Advanced Audio Coding (AAC) was specifically engineered to be the successor to MP3. It achieves noticeably better sound quality at identical file sizes. This means you can squeeze more tracks onto your phone's storage without sacrificing the punchiness of the bass or the clarity of the vocals.

True privacy for your collection

You shouldn't have to surrender your personal listening habits to a random server just to change a file type. Unlimited Convert shifts the processing burden to your computer's RAM. We never see what you convert, and you never have to wait in a server queue.
