MP4 to MP3 Converter

Convert MP4 to MP3 online in your browser

This free MP4 to MP3 converter takes the sound from an MP4 video and saves it as an MP3 file you can play on any phone, car stereo, laptop or music player. There is no app to install and no account to create. Unlike most online converters, VidHaul does not upload your video to a server: the whole conversion runs inside your browser on your own device. That makes it fast for everyday files and private for anything personal, such as a family video, a recorded meeting or a lesson you filmed on your phone.

People convert MP4 to MP3 for many reasons. You may want to listen to a recorded talk while walking, keep only the music from a clip of your own performance, send a lighter audio file instead of a big video, or load a recording into an audio editor. An MP3 is usually a small fraction of the size of the MP4 it came from, because the picture is dropped and only the sound is kept.

How to convert MP4 to MP3

1. Click Choose file at the top of this page, or drag and drop your MP4 onto the box.
2. Under MP3 bitrate, choose 128, 192 or 320 kbps. If you are not sure, keep the default 192 kbps.
3. Press Start. A progress bar shows how far the conversion has got.
4. Click Download. Your file is saved with a clear name based on the original, and you can see the size before and after.
5. Use Convert another file to do the next one.

That is all it takes to change MP4 to MP3. The same steps work on a desktop computer and on a phone, as long as you use an up-to-date browser.

How to convert MP4 to MP3 on a phone

On Android, open this page in Chrome. On iPhone or iPad, use Safari or Chrome. Tap Choose file, pick the video from your gallery or Files, and press Start. Because the work happens on the phone itself, a long video takes longer than on a laptop, and very large files (roughly over 1.5 GB) may be slow or fail on phones because everything is processed in the device's memory. For a long recording, a computer is the more comfortable choice.

How to convert MP4 to MP3 on Windows or Mac

You do not need to download an MP4 to MP3 converter for Windows or a separate app for Mac. Open the page in Chrome, Edge, Firefox or Safari, drop the video in and press Start. The MP3 lands in your usual Downloads folder, ready to add to a playlist or audio editor.

Choosing the right MP3 quality

MP3 quality is measured as a bitrate in kilobits per second (kbps). A higher number keeps more detail but makes a bigger file. Here is a simple guide:

Converting cannot add quality the source did not have. If the audio inside your MP4 was recorded at a low quality, saving it at 320 kbps only makes the file bigger, not better. In that case 192 kbps is usually enough.

Why use this free MP4 to MP3 converter?

• Private by design. Your video is never uploaded, so it is suitable for confidential files.
• Free and unlimited. No sign-up, no watermark, no daily limit.
• No app needed. It works online in the browser you already have, on phone and PC.
• Simple choices. Just one setting – the MP3 bitrate – so there is nothing to get wrong.

Speed depends on your device. A modern laptop converts a typical MP4 quickly; an older phone takes longer. Very old browsers cannot run the converter at all, and the page will show a message if that happens. In that case, update your browser or try another one.

What if my MP4 has no sound?

Some MP4 files, such as screen recordings made with the microphone switched off, have no audio track at all. If that is the case, the converter shows a clear “no sound” message instead of giving you an empty MP3. Check the video in a player first: if you hear nothing there, there is nothing to convert.

Other formats and related tools

This page is made for MP4 files. If your video is a MOV from an iPhone, an MKV or a WebM, use thevideo to MP3 converter, which accepts many more formats. Already have audio in another format? Try M4A to MP3 or WAV to MP3. Once you have your MP3, you can trim it to the part you need with the MP3 cutter – handy for making a ringtone. And if you want to keep the video but share a smaller version, thevideo compressor can shrink it.

Please only convert videos you own or have the right to use.
