Our free online audio extractor lets you pull the audio track from any video file and save it as MP3, AAC, or WAV — without uploading your video to any server. Whether you want to rip audio from an MP4 lecture, extract background music from a MOV clip, or convert a video to MP3 for your podcast workflow, this browser-based tool handles it instantly 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.

Frequently Asked Questions
Can I extract audio from a video without uploading it?
Yes — our free audio extractor runs entirely in your browser using WebAssembly technology. You select a file from your device, and all processing happens locally. Nothing is ever uploaded to a server.
What audio format should I choose — MP3, AAC, or WAV?
Choose MP3 if you want maximum compatibility across all devices and players. Choose AAC if you want better audio quality at the same file size (especially for music). Choose WAV if you need lossless audio for professional editing or archival purposes — WAV files are much larger but contain every bit of the original audio data.
How do I convert a video to MP3 for free?
Upload your video to our free audio extractor, select MP3 as the output format, choose your desired bitrate, and click Extract. The MP3 file will download directly to your device. No upload, no account, no fee.
Can I extract audio from a video on my phone?
Yes. The tool works in mobile browsers on both iOS and Android. Open the page in Chrome or Safari, select your video from your phone’s storage, and extract the audio. No app installation required.
