Why people use it
Files stream straight to your device. We keep no copy of the video or the link.
No sign up, no email, no tracking pixel. Paste a link and save the file.
Every tool on the site is free to use, with no daily download cap.
We pick the highest stream the source offers, up to 4K where it exists.
One paste, one click. No queues, no waiting rooms, no forced ads between steps.
Runs in any modern browser on phone, tablet and desktop. Nothing to install.
How to pull the audio out
Choose your video file, leave the output on MP3 and press convert. The audio track is copied out and encoded, the picture is discarded.
The file keeps its original name with an mp3 extension, so a folder of lectures or interviews stays organised.
Why 192kbps
It is the point where speech and most music are indistinguishable from the source for normal listening, while the file stays around one and a half megabytes a minute.
If you need a lossless copy for editing, choose WAV in the full converter instead.
Nothing leaves your device
The conversion runs inside the browser tab, so a recording of a private meeting or a client's footage never touches a server.
There is also no queue, which is why a short clip is finished almost as soon as you press the button.
Questions people ask
Is the MP4 to MP3 converter free?
Yes, with no account and no limit on how many files you convert.
Does the audio lose quality?
MP3 at 192kbps is a small step down from the source, and for speech or casual listening it is not audible.
Can I convert other video formats?
Yes. MOV, WEBM, MKV and AVI all work the same way.
How big a file can I convert?
Up to two gigabytes, which covers a long recording comfortably.
Is my video uploaded?
No. The whole conversion happens in your browser.
