How it works
Extract Audio from Video pulls the soundtrack out of any video file your browser can play. Drop an MP4, WebM or MKV, and the tool decodes the file, takes the audio track, and re-encodes it as MP3 or WAV - the video frames are simply discarded. It is the fastest way to save a song from a clip, grab audio from a lecture recording, or sample a sound from a video.
There is no video processing involved: the browser's own media decoder does the heavy lifting, which is why format support matches what your browser can play. The extracted audio is the exact decoded soundtrack - quality depends only on the output format and bitrate you choose.
Everything runs client-side: your video is decoded and the audio encoded in your own browser tab, so files never leave your device and nothing is uploaded to any server.
Frequently asked questions
How does audio extraction work?
Your browser already knows how to play video files - this tool asks it to decode the file, takes the audio track it produces, and ignores the video frames entirely. No video is processed, re-encoded or kept; only the soundtrack flows through to the MP3/WAV encoder.
Which video formats are supported?
Whatever your browser can decode: MP4 (H.264/AAC) works everywhere, WebM works in Chrome/Firefox/Edge, and MKV support varies by browser. If the file plays in your browser, its audio can be extracted.
I get a "could not decode" error on my video. What now?
The usual culprits: the file is corrupt or truncated, it uses a codec your browser does not support (try Chrome, which handles the most formats), or it exceeds the 100 MB limit. Converting it to MP4 with a desktop tool and retrying almost always fixes it.
Is my video uploaded anywhere?
No. Decoding and encoding happen entirely in your browser tab. Your video never leaves your device.
