What is an Online Audio Extractor?

Not only can it quickly and conveniently extract clean, standalone audio files from video—converting MP4 to MP3, MOV to MP3, and more—it also exports a variety of audio formats. This includes high-quality WAV, FLAC (lossless), compressed formats like MP3, M4A, WebM, OGG, and even the iPhone ringtone M4R format! If you don’t need conversion, it can also export the original audio track from the video as-is.
