Why extract the audio of a video
Only the sound comes back
Upload a video and you get an MP3 holding its audio track. The picture is dropped, so a lecture, an interview or a song you filmed turns into a file any music player can open.
Bitrate, sample rate and channels
The settings panel offers bitrates from 64 to 320 kbps, sample rates up to 48000 Hz, stereo or mono, variable bitrate, volume normalization and a switch to strip cover art.
Nothing to install
The conversion runs on our servers over an encrypted connection. There is no software to download and no account needed to pull an audio track out of a video.
What you can set
Bitrate decides how much of the audio the MP3 keeps. 64 kbps is enough for speech, 192 kbps is what this page starts on, and 320 kbps is the highest the format takes. A higher number sounds better and makes a bigger file.
Variable bitrate is the alternative to a fixed number: the encoder spends more on busy passages and less on quiet ones, which usually sounds better at a similar file size. Sample rate reaches 48000 Hz, the rate video is normally recorded at, and 44100 Hz is CD quality.
Channels can stay stereo or fold down to mono, which is the right choice for a voice recording. Two switches finish the panel: normalize the volume to an even level, and remove embedded cover art.
Bitrate and channels start on 192 kbps and stereo. Every other field starts on Auto, which leaves the decision to the conversion engine.
The page opens with 192 kbps selected and stereo enabled.
Which videos work, and what you get back
MP4 is what most people bring, and it is not the only input that works. MOV from an iPhone, AVI, WEBM, MKV, WMV and FLV all carry an audio track that can be lifted out the same way.
What comes back is always an MP3, the audio format that plays on essentially every phone, car stereo, browser and music player.
You can add several videos at once and each one returns as its own MP3 with the same settings applied, or paste a link instead of uploading a file.
Free to use, and private by default
Extracting an audio track is free and needs no account. Every upload and download runs over an encrypted connection, so your recording cannot be read on the way.
Processing is fully automated: nobody listens to your recordings and they are never used to train AI models. You keep the copyright and the ownership of both the video you upload and the MP3 you get back.
The servers that do the work are in Europe.

Questions about converting MP4 to MP3
How do I convert an MP4 to an MP3?
Upload the video, choose a bitrate if you have one in mind, and start the conversion. The MP3 is ready to download when it finishes, and there is nothing to install first.
Which video formats can I upload?
MP4, MOV, AVI, WEBM, MKV, WMV, FLV and the other common video formats. Whatever goes in, an MP3 comes out.
What bitrate should I choose?
192 kbps is the starting value and a safe answer for music. For speech, a podcast or a lecture, 64 to 128 kbps sounds much the same and gives a far smaller file. 320 kbps is the maximum MP3 allows.
Will the MP3 sound as good as the video?
The MP3 can only hold what the video's audio track already contains. A quiet or noisy recording stays quiet or noisy, and asking for 320 kbps does not add detail that was never recorded.
Can I convert several videos at once?
Yes. Add as many videos as you like and each one is converted separately with the same settings, then returned as its own MP3.
Does it cost anything?
No. Converting a video to MP3 here is free and does not require an account. A paid plan raises the upload limit and how many files you can process at once.
