Extract Audio from Video
Extract audio from video in any format and save it as MP3, WAV or M4A. Free and unlimited, no sign-up, and the file never leaves your device.
Your file is converted in your browser and never uploaded to our servers.
How to extract audio from video in three steps
The whole job happens in this browser tab, so there is no upload bar to wait for.
- 1
Drop in any video
Drag a file onto the box or tap to pick one: MP4, MOV, MKV, WebM, AVI, FLV, WMV, 3GP, TS and more. On first use your browser fetches the converter, about 9 MB, and caches it.
- 2
Pick the output and quality
Choose MP3, WAV or M4A. For MP3 and M4A, pick 128, 192 or 320 kbps; 192 is the default and fine for most listening.
- 3
Save the audio file
Press the button and download the result. It keeps your file's name with the new extension, so lecture-week3.mkv becomes lecture-week3.wav.
A video to audio converter that runs on your device
Nothing is uploaded
FFmpeg, compiled to WebAssembly, reads the video straight from your disk inside the tab. Many online converters send your file to their servers first; this one never sends it anywhere.
Any container in, one track out
If FFmpeg can read it, it works here: phone MOVs, MKV files from your own streams, old AVI camcorder clips, WebM screen recordings. The first audio track becomes your file.
No upload wait
A long recording never has to crawl up to a server before work starts. How fast it finishes depends on your device, not your connection.
Free with no counter
No sign-up, no watermark, no daily cap and no email. Convert one file, then the next, as often as you like.
MP3, WAV or M4A: which audio format to choose
When you extract audio from video, the output format should follow what you do with the file next.
| MP3 | WAV | M4A | |
|---|---|---|---|
| Best for | Listening, sharing, podcasts | Editing, mixing, transcription | Apple Music, iPhone, iPad |
| Quality setting | 128, 192 or 320 kbps | 16-bit PCM, no bitrate to pick | 128, 192 or 320 kbps |
| File size | Small | Largest by far | Small |
| Compression | Lossy | None: a lossless copy of the decoded audio | Lossy (AAC) |
| Editing later | Each re-save loses a little more | Edit and re-export freely | Each re-save loses a little more |
| Plays on | Almost anything, car stereos included | Computers, audio editors, most players | Apple devices and most modern players |
Why people turn video into audio
Common reasons to extract audio from video, with the format that suits each one.
Podcast from a video call
Recorded the interview on Zoom, Meet or Teams? Pull the voice track as WAV, clean it up in your editor, then export the episode.
Lecture audio for the commute
Turn a recorded class or webinar into a 192 kbps MP3 and listen on the bus instead of watching a screen.
Music from your own clips
Filmed a recital, a gig or a band rehearsal on your phone? Save it as a 320 kbps MP3 for your music library.
Voice-over and sample material
Lift the narration from an old tutorial to reuse over a new screen recording, or grab a sound from your footage as WAV for a beat or an edit.
Input for transcription
An audio file is a fraction of the video's size, so it uploads faster to a transcription service and opens in any audio editor.
Speeches from home videos
Keep the toasts from a digitized wedding tape or an AVI camcorder file as standalone audio that family can play on any phone.
Other ways to extract audio from video: VLC, QuickTime, iPhone
On Windows, Mac or Linux, the free VLC player can do it. Open Media, then Convert / Save, add the video, choose the Audio - MP3 profile, give the file a name ending in .mp3 and press Start. VLC suits batches, but the settings sit deep in menus.
On a Mac, QuickTime Player has File, Export As, Audio Only. It is quick, but it saves M4A only, with no MP3 or WAV option.
On an iPhone, the Shortcuts app can do it with an Encode Media action set to Audio Only. Or open this page in Safari, pick the video from Photos or Files and convert it here.
Video to audio mistakes that cost quality
Mistake: Choosing 320 kbps to make a quiet phone clip sound better.
Do this instead: Bitrate cannot add detail the source never had. Use 192 kbps for speech and keep 320 for music you want to archive.
Mistake: Saving as MP3 when you plan to edit, then exporting MP3 again.
Do this instead: Pick WAV for anything going into an editor. Encode to MP3 once, at the very end.
Mistake: Converting a two-hour recording on an older phone.
Do this instead: Very large files can fail on phones with little memory. Use a desktop browser for long videos.
Mistake: Expecting the second language or commentary track of a multi-track file.
Do this instead: The converter takes the first audio track. For another one, use a desktop tool such as VLC or FFmpeg that lets you pick the track.
What happens to your video
It stays on your device
The file is read locally and never copied to a server. Your browser downloads only the page and the open-source FFmpeg converter, which comes from the jsDelivr CDN.
Free and unlimited
There is no account to create, no watermark and nothing counting your conversions.
Plain limits
One file at a time and the first audio track only. We don't promise a maximum file size: big files depend on your device's memory.
