About the Extract Audio from Video
Want just the sound from a video, such as a song, a talk, an interview or a voice message? This tool pulls the audio track out of MP4, MOV, WebM and MKV videos. By default it copies the sound exactly as it is in the video, for example AAC into an M4A file or Opus into an OGG file, which is instant and loses no quality. You can also save it as uncompressed WAV for editing, or as M4A for small files that play everywhere. Everything happens in your browser.

Original, WAV or M4A?
Pick based on what you will do with the sound.
- Original: exact copy, instant, smallest
- WAV: for editing in Audacity, GarageBand or a DAW
- M4A: small, plays on phones, cars and computers
Why copying is lossless
The sound in a video is already compressed. Copying it into an audio file keeps every bit exactly. Converting to another lossy format would compress it a second time and lose a little quality.
How it works without uploading
Your browser has a built-in media engine (WebCodecs) that phones and computers use to play and record video and sound. This tool uses it through Mediabunny, an open-source media library, to read your file, change it and write a new one, all inside the page. Speed depends on your device, but most clips take only seconds.
Typical uses
Saving a recorded lecture or podcast as audio for listening on the go, keeping the music from a party video, getting a voice note out of a screen recording, or preparing sound for transcription.
Respecting rights
Only extract sound you have the right to use, such as your own recordings or content licensed for reuse.
Checking which sound a video has
After you pick a video, the menu shows which format Original will give you and the note below names the codec inside the video. Phone videos usually contain AAC, so Original gives an M4A that plays on iPhones, Android phones, Windows and Macs. Screen recordings from browsers usually contain Opus, which gives an OGG file.
Editing the sound afterwards
WAV is the safest format for editing programs, because it is uncompressed and every editor reads it. After editing, export to M4A or MP3 for sharing. If you only need to cut the beginning or end, the Audio Trimmer can do it without an editor.
Phone and computer
Pick a video from your phone's gallery; the audio file saves to your downloads. For a ringtone clip, try the M4R Ringtone Maker, and to silence the video instead, use Mute Video.

Frequently asked questions
Which format will I get with Original?
It depends on the video: AAC sound gives an M4A file, Opus or Vorbis gives OGG, MP3 gives MP3, and anything else becomes WAV.
Can I get an MP3?
If the video's sound is already MP3, Original gives an MP3. Otherwise browsers can't encode MP3, so choose M4A, which plays on all the same devices and sounds better at the same size.
Why is the WAV file so big?
WAV is uncompressed: about 10 MB per minute of stereo sound. Use it for editing, then export a smaller file.
Does it work with audio-only files?
Yes. You can also use it to change an audio file to WAV or M4A.
Which browsers work best?
Chrome and Edge on computers and Android support the most formats. Safari 16.4+ and recent Firefox work too, but some codecs may not be supported there.
Is my file uploaded?
No. It is processed on your own device with your browser's built-in media engine, so nothing leaves your phone or computer.
Can I extract only part of the sound?
Extract the whole track here, then cut it with the Audio Trimmer.
