Extract Audio from Video
Turn a video into MP3: keep the soundtrack alone, ready to listen to or transcribe.
About this tool
A filmed conference you want to listen to again while walking, a recorded lecture headed for a transcription tool, an interview where only the speech matters, the music from a wedding video: in all these cases the picture is dead weight and accounts for ninety per cent of the file. Drop the video, and the tool shows its length, its first frame and whether it can detect an audio track, then pulls the sound out on its own. The default result is an MP3 that plays absolutely everywhere, from a phone to a car stereo, and converting video to MP3 this way typically shrinks the file by a factor of ten to fifty.
One option is worth knowing about: the M4A format copies the audio track across untouched when it is already AAC — which is the case for nearly every MP4 and every phone recording. That makes it completely lossless and almost instant, since all it really does is strip the picture away. If the track uses another codec, the tool falls back to an MP3 re-encode by itself and tells you, instead of failing in silence. Nothing leaves your browser, which matters more than usual for a recorded meeting or for material that is not yet yours to publish.
Frequently asked questions
Which video formats can I drop in?
MP4, MOV, MKV, WebM, AVI, M4V, 3GP and WMV — screen recordings, phone footage, video-call exports and camera files all qualify. The extraction engine reads considerably more containers than the browser's built-in player does, so even when the first-frame preview refuses to appear and the tool cannot tell you whether there is an audio track, there is still a good chance the sound comes out perfectly fine.
Does the sound lose quality during extraction?
In M4A, no: the track is copied bit for bit when it is already AAC. In MP3 there is a re-encode — the original track was already compressed, and it gets compressed a second time. At 192 or 320 kbps the difference stays inaudible for speech and very discreet for music, but it is a real second generation.
Can I extract the audio from a YouTube video?
This tool works on a file you already have on your device. It downloads nothing from any platform and circumvents no protection. If you legitimately hold the video file — your own recording, a video-call export, footage you own the rights to — it will pull the soundtrack out of it for you.
How long does it take?
A few seconds in M4A, since there is nothing to recompute. In MP3, anything from a few seconds to a handful of minutes depending on length: audio processes far faster than video. The very first run adds the engine download (around 30 MB), which is then kept in cache for every later job.
Is it really free, with no sign-up?
Yes — the tool is free, needs no account and has no usage limit. Processing happens locally in your browser, so your data never leaves your device.
