Our free online audio extractor lets you pull the audio track from any video file and save it as MP3, AAC, WAV, OGG, or FLAC — without uploading your video to any server. Whether you want to rip audio from an MP4 lecture, extract background music from a MOV clip, convert a video to MP3 for your podcast workflow, or export lossless FLAC for editing, this browser-based tool handles it with zero cost and no signup required.
Everything runs locally in your browser using WebAssembly-powered FFmpeg, so your video stays completely private on your device. This makes it ideal for extracting audio from sensitive recordings, corporate presentations, interviews, or any footage you can’t risk uploading to a third-party cloud service.
