Anyway, here are the detailed steps. Check them now.

1. Open VLC and click on the Media button to locate the Convert/Save feature. Or you can just use the shortcut CTRL + R to pop up another page.

Part 4. How to Convert MP4 to MP3 Online

There are probably lots of users who love the online tools. They are simple to use, no complicated operating steps. There is no need to download some installation file. Etc. Honestly, online tools help us a lot in our daily lives.

However, they also have some shortcomings, which we felt bound to tell you. Most online tools have limits on the size of the importing file, like a maximum of 200MB. They need a network connection, which is very different from desktop applications, like VideoProc, Windows Media Player, VLC, and iTunes. The third one is about the data security issue. Online tools move your files to the web servers to process. So there is a high risk that your data would be deleted, lost, or leaked.

So basically, we would not suggest our users get some online tools. While since there are some users still looking for it, here is one we have tested for you. It is ZAMZAR.

Supported platform:
Any OS (Windows, Mac, Linux, iOS, Android) that has a web browser.

ZAMZAR MP4 to MP3 online tool

There are just three steps needed, add files > choose the target format to MP3. There are also some other format options > Click Convert Now button to start.

Besides the MP4 files saved on your computer, the online video files are also supported. You can simply put in the link, ZAMZAR will also help you change it to MP3.

The converted file can only be stored for 24 hours in that server. So please remember to download it to your local drive in time.


  • - The output audio quality is sound.
  • - Intuitive: Show you the file name, file size and progress.
  • - You can choose Email when done, which will be convenient for some people.
  • - It saves you local storage since you can save the file in the cloud.
  • - The output mp3 file is much smaller than the input, in my test, Input: 10083kb -> output: 465kb.


  • - Does not allow you to change the output file name.
  • - The conversion speed depends heavily on your network condition.
  • - If you want to convert big file (up to 2GB), you should sign up and spend some money.

Part 5. Can I Convert MP4 to MP3 Using Windows Media Player?

If you are a Windows user, you may know Windows Media Player, a powerful built-in application on Windows. There are lots of hidden features which we may have not known before, including "Rip Music". This feature seems be able to convert an MP4 to MP3, although it is somewhat hidden. But is it still so? Let's see our test first.

In the following , we will unravel this mystery with detailed steps.

1. Open the MP4 file with Windows Media Player.

2. At the library page, find the Organize button, click it, and choose the Options feature. Then we will go to another unique page with many settings.

3. Find the Rip Music. In this feature, you are enabled to rip the video file to audio. Then choose the location where you plan to rip the video.

However, when we chose the location to the desktop, or some other locations on the computer, the music ripping did not work. So we guess Windows Media Player disabled some options in the recent updates. So the MP4 to MP3 conversion using Windows Media Player failed. And we are not alone. See the user comments in this post.

In the Rip settings, you can set the format to MP3 right below the Format features. In Audio quality, you can adjust the MP3 file quality. And after all these settings are done, click the OK button to start.

Windows Media Player Rip Music


  • - As a player app, it is convenient to preview and playback.
  • - Provide many format/device options for your output.
  • - Flexible for you to adjust output quality, Sample Rate, Bit Rate.


  • - This conversion feature is hidden.
  • - You cannot preview the progress or to see the remaining time or length.
  • - It does not provide access to the output location directly, so you may fail to find the output file.
  • - You cannot rename the output file (you can only choose to sort based on the detailed information of the files).
  • - It is not very intuitive sometimes. It is not convenient to switch the interface or return.


Even though we have narrowed down dozens of choices to only 5 ones, which we recommend, there still needs users to choose one among these 5 MP4 to MP3 converters. For some users, this is still hard, right?

So to make it simpler, we would strongly recommend you choose the first one, ie. VideoProc. It is much easier to use than Windows Media Player, VLC, and iTunes, but also much safer than the online tools. Most importantly, with it, you can polish your MP4 video in the way you want. So why not give it a try now?
