Audio Extractor

Media

Extract audio from video files. Upload MP4, WebM, or MOV and download as M4A, WebM, OGG, or WAV.

Why extract audio from video?

Extracting audio from video files is a common task for content creators, podcasters, musicians, and developers. You might need to pull a voiceover from a screen recording, extract background music for analysis, convert a video interview into a podcast episode, or isolate dialogue from a film clip. Traditional tools require software installation and often upload your files to remote servers, raising privacy concerns. This tool processes everything locally in your browser — your files never leave your device.

Supported formats and how it works

This tool accepts any video format your browser supports, including MP4, WebM, MOV, and AVI. You can extract audio as M4A/AAC (Apple-friendly, available in modern browsers), WebM and OGG with Opus codec for compact web-friendly files, or WAV for lossless quality. WAV uses direct audio decoding for faster extraction, while M4A, WebM, and OGG use real-time MediaRecorder capture.

Audio formats explained

M4A (AAC) offers excellent quality at small file sizes and is preferred on Apple devices and iTunes. WAV files are uncompressed and provide the highest quality but produce large files. WebM and OGG use the Opus codec, which delivers near-transparent quality at a fraction of the file size. When choosing a format, consider your use case: M4A for Apple ecosystem and broad compatibility, WAV for professional editing, WebM for web streaming, and OGG for open source projects.

Frequently Asked Questions

Is my video uploaded to a server?

No. All processing happens entirely in your browser using the Web Audio API. Your video never leaves your device, making this tool safe for sensitive or proprietary content.

Why is WAV extraction faster?

WAV uses direct audio decoding — the browser decodes the entire audio track at once. This is much faster than real-time playback. M4A, WebM, and OGG use MediaRecorder which captures audio as the video plays, taking roughly the video duration.

Can I extract audio from YouTube videos?

This tool works with local video files only. You need to have the video file on your device. Downloading videos from YouTube may violate their terms of service.
