What Video Audio Extractor does, with a checked example

Pick a video file, choose MP3, WAV, or OGG, and this page returns just the sound as a downloadable audio file. The tool pulls the audio track out of the video, re-encodes it in the format you picked, and leaves the pictures behind entirely - a 4K movie and a 360p clip carrying the same audio yield the same result. The thing users usually get wrong is expecting an upgrade: this is a re-encode, not a copy, so the output can never sound better than the audio already inside the source video. Everything runs in the browser; the file never leaves your machine.

Worked example

A concrete input and expected output from the current implementation.

Input

Choose `beach_walk.mp4`, a 5-minute phone video, in the file picker, then set the output format to MP3.

Expected output

A download named `beach_walk.mp3` appears: the same 5 minutes of audio with no video frames, typically a fraction of the video's file size. The exact size depends on the encoding settings.

Extraction decodes the video's audio track and re-encodes it in the chosen format, so the download keeps the track's content and length but contains no pictures. It is a fresh encode, not the original track.

How the result is produced

What extraction does

The tool reads your video and works only with its audio track, ignoring the picture entirely. It decodes that track, encodes it again in the output format you selected, and hands you a new audio-only file for download. Video resolution, frame rate, and video codec have no effect on the result - only the audio track and the format you choose.

The three formats

MP3 is lossy and plays almost anywhere, making it the safe default. WAV stores audio uncompressed - roughly 10 MB per minute for CD-quality stereo, with no added encoding loss, which is why editors prefer it. OGG is a container that in practice holds Vorbis audio: lossy compression comparable to MP3, often a little more efficient at equal quality, but with weaker support in older hardware players.

Good uses

Listening on the move - convert a recorded lecture, meeting, or interview to MP3 and play it on a phone or in a podcast app without carrying the video.
Audio editing - export a clip from a music video or a sound effect as WAV, which is uncompressed and safe to re-edit without extra generation loss.
Keeping just the sound - archive the audio of a long home video or presentation as a small separate file, or reuse that track in another project.

Limits and checks

Quality ceiling: the download can never sound better than the audio track inside the video. If that track was already compressed hard - common in screen recordings, video calls, and small downloads - every output format preserves the loss; none of them restores it.
WAV size: uncompressed audio is huge. Stereo WAV runs about 10 MB per minute, so a long video can produce a WAV dozens of times larger than an MP3 of the same sound - check the format before committing to a 45-minute export.
Not a copy: the result is a fresh encode, not a bit-identical duplicate of the video's track. Most MP4 videos carry AAC audio, so an MP3 or OGG export applies a second lossy stage, and the file will differ from the original track even where the difference is inaudible.

Common questions

Is my original video file changed?

No. The tool only reads the video - the original stays untouched and nothing is uploaded anywhere. The output is a new download you can keep or discard, and you can run the same file through again with a different format whenever you like.

Which format should I pick?

MP3 if you want it to play anywhere at a small size - the usual choice for phones and portable players. WAV if you plan to edit the audio or want no additional lossy compression, accepting files of about 10 MB per minute. OGG if your target is open-source software and you want efficient compression, but expect some hardware players to refuse it.
