What Is Extract Audio from Video?

Extract Audio from Video is a free online video to audio converter. It takes an input video — MP4, MOV, MKV, WebM, AVI and other common formats — and writes out a pure audio file in MP3, WAV, M4A or OGG. Use it as an MP4 to MP3 converter, MOV to MP3 converter, MKV to WAV ripper, or simply to get audio from video without re-encoding the whole file. Everything runs locally via FFmpeg WebAssembly, so your videos never leave your device.
