Everything you need to know about audio extractor.

Audio Extractor — free & online

Pull audio tracks from MP4, AVI, MOV, and other video formats. Get just the sound you need without any video editing software. No downloads, no sign-ups, and no accounts. Editing and preview run locally in your browser using the Web Audio API; exporting sends your file over an encrypted connection to our processing server, which deletes it as soon as your download finishes.

How does Audio Extractor work?

Simply upload your audio file — MP3, WAV, OGG, FLAC, or M4A — and use our intuitive editor to make your changes. Upload video, Choose format, Extract, Download audio. Once you're satisfied, export the result in your preferred format instantly.

Who is Audio Extractor for?

Whether you're a podcaster, musician, content creator, or just someone who needs a quick audio edit, Audio Extractor is built for you. It works on any device — desktop, tablet, or mobile — across all modern browsers including Chrome, Firefox, Safari, and Edge.

Taking the audio out of a video

A video file is a container holding separate video and audio streams alongside each other. Extraction discards the video stream and keeps the audio, which means there is no quality loss involved in the extraction itself — you are copying out a stream that was already there, not converting a picture into a sound.

MP4, MOV, MKV, AVI and WebM all work, along with most other common containers. Which audio codec sits inside varies — usually AAC in MP4 and MOV, often Vorbis or Opus in WebM — but that is handled for you; you choose the output format and the extraction takes care of the rest.

This tool does upload your file

Worth being explicit about, because it differs from the audio tools. Reading a video container and demuxing its streams needs a real decoder, so the file is sent over an encrypted HTTPS connection to be processed, then deleted as soon as your download completes. Nothing is stored, nothing is inspected, and no copy is kept — but the upload does happen, and video files are large, so expect the transfer itself to take the bulk of the time.

The 500 MB limit applies to the video, not the audio you get out of it. A long recording in a high bitrate can exceed it easily. Trimming the video in another tool first, or extracting from a lower-resolution copy, is the way around it — the audio stream is usually identical either way.

Choosing the output

For lectures, interviews and anything speech-based, MP3 is the sensible target: small, universally playable, and speech survives compression well. For music extracted from a performance video, or anything heading into further editing, choose WAV or FLAC. The audio inside a video is usually already lossy, so re-encoding it to another lossy format compounds the loss — going to FLAC avoids adding a second generation of it, even though the source was not lossless to begin with.

Common uses are pulling the audio from a lecture recording to listen to while travelling, lifting a soundtrack from a performance video, saving a voice memo that was captured as video by accident, and getting a transcribable audio file out of a meeting recording. Once extracted, the Noise Remover and Audio Compressor are the usual next steps for speech.

Frequently asked questions.

Everything you need to know about Audio Extractor.

What video formats are supported?

MP4, MOV, MKV, AVI and WebM cover very nearly everything. The picker also accepts audio files, and extraction runs through ffmpeg on the server, which understands a good many more containers than that list.

What audio format will I get?

MP3, WAV, OGG, FLAC or AAC. Choose WAV or FLAC to avoid adding any further loss on top of what the video already had, or MP3 or AAC for a smaller file.

Is the video uploaded anywhere?

Yes. Extracting audio needs a video decoder, so the file is sent over an encrypted connection to our processing server, and it is deleted as soon as your download finishes. We keep no copies.

Is there a file size limit?

500 MB per file. Video is bulky, so this is the tool most likely to run into it — if your file is over the limit, trim the video first or extract from a lower-resolution copy, since resolution has no bearing on the audio track.

How do I extract audio from an MP4 video for free?

Drop the MP4 in, choose an output format and export. The video stream is discarded and only the audio is encoded, so nothing about the picture affects the result or the time it takes.

Does extracting audio from a video lose quality?

Only if you re-encode to a lossy format. Audio inside a video is usually already AAC, so exporting to MP3 adds a second lossy generation — export to WAV or FLAC to avoid that.

Can I extract audio from a YouTube link?

No. You need the video file itself; there is no URL field, and downloading from streaming services generally breaches their terms. Extract from video you own or otherwise have the right to use.

What happens if the video has several audio tracks or languages?

One track comes out — the default the decoder considers best. If your file carries separate language or commentary tracks, there is no way to choose between them here.
