It can not only help you convert MP4 to MP3, but also convert other videos to WAV, AAC, AC3, WMA, M4A, OGG, etc. at an incredible fast speed. Moreover, it boasts more features to cut/trim audio, download videos and music from online, and solve other multimedia problems. All these features are accessible in a clean and user-friendly interface. The only drawback is that you can’t have it on other platforms except for Windows.

2. 4Media MP4 to MP3 Converter

Another amazing free MP4 to MP3 converter for Windows is 4Media MP4 to MP3 Converter. The software has got a very simple and intuitive interface so new beginners can handle it without much trouble. You can easily convert your wanted video files to various audio files, such as MP3, WAV, AC3, WMA, M4A, OGG, and AAC swiftly. Besides, it also supports multithreading and batch conversion, so the conversion speed is super-fast. Yet, the trial version only allows the utmost 3 minutes of every file to be converted, which holds a big turn-off for many users.

3. Free MP4 MP3 Converter

As the name suggests, Free MP4 MP3 Converter is free software to convert MP4 to MP3. But you can’t perform any other multimedia activities like the above converters because it is a lite program that only takes care of the MP4 to MP3 conversion. And due to this sole function, you can have a straight conversion experience without interruption. But the conversion speed is rather slow. Moreover, Free MP4 MP3 Converter is only compatible with the Windows system.

4. Format Factory

Format Factory is a classic multifunctional media processing tool on Windows that can perform various kinds of conversions among videos, audio, and picture files. And using the program to convert MP4 to MP3 is more than enough, just like many other converters. But what it outshines other rivals is its capability to batch convert up to four files, speeding the conversion process greatly. Other benefits of using Format Factory include super-easy operations, conversions for different needs, and DVD to digital backup. But keep in mind that Format Factory is ad-supported freeware. You might get unwanted software installed on your computer by a misclick on the ads.

5. MediaHuman Audio Converter – Best Free MP4 to MP3 Converter for Mac

If you are looking for the best MP4 to MP3 converter for the Mac system, MediaHuman Audio Converter is the answer. It is a very simple and clean converter designed to convert not only audio but video to all key audio formats, including MP3, AAC, OGG, AIFF, and WAV, at no cost.

Another shining feature of MediaHuman Audio Converter is its ability to search cover art automatically for the converted music and then export the music file to iTunes. Don’t miss this software if you are a Mac user who tries to convert a music video to MP3.

6. VLC

In the eyes of many users, VLC Media Player is just a popular cross-platform media player to play video and audio files. If you see it in the same way, what comes next might surprise you. You guessed it right! VLC Media Player is also a decent MP4 to MP3 converter app that can handle MP4 to MP3 conversion without much hassle. This hidden VLC feature can be accessed through the “Media” > “Convert / Save…” option where you can add your wanted MP4 file and choose MP3 output profile and finish the conversion. But one thing worth noticing is that errors occur often when using VLC to do conversions. Yet, its popularity and compatibility still make it a good option for basic conversion tasks.

Tips: VLC has more amazing features than you think. Check them out: Download Video, Play DVD, Play Blu-Ray, Rip CD, Rip DVD, Stream Network.

7. Any Video Converter Free

Any Video Converter Free is another remarkable MP4 to MP3 converter app for Windows and Mac OS. You can use it to convert any video to MP3 and many other popular formats completely for free. But it will only let you do one conversion at a time. Yet, it’s got great conversion speed, and it takes a few seconds to complete multiple files conversions. There’s one thing worth mentioning, though, which is about its usability. From what many of its users say, Mac users will have a smoother user experience with this software compared with Windows users, for the Mac version is more direct and simple while the Windows version features a more complex interface that new beginners may find it hard to get started. For advanced users, however, both versions are great.

8. Video to MP3 Converter - Best Free MP4 to MP3 Converter App for Android

9. Video MP3 Converter

Video MP3 Converter is an impressive Android application that allows you to edit your video files and subsequently convert them to audio files for free. It supports various file types, including MP4, FLV, WebM, WMV, and 3GP video files, as well as MP3, OGG, AAC, and even more audio files. And during the video to audio conversion, you can edit metadata of the audio, such as title, artist, and album. There are some disadvantages, however. It does not have good support for large files, and the conversion time is long.

10. Convertio

If you want to try some online MP4 to MP3 converters, Convertio is a good place to start. The most popular online converter enables you to complete MP4 to MP3 conversion with no downloads, suitable for mobile users running short of their device space. But that’s just one of the many bonuses Convertio gives you. You will also find Convertio very helpful when you learned that it supports file uploading from Dropbox, Google Drive, and URL besides your local file folder. And that means you can make conversion happen in the cloud without consuming any capacity from your device. It has its limits, though. To keep a fast and easy conversion, Convertio only allows free users to upload files smaller than 100MB.

11. Online-Convert

Online-Convert makes another decent online free MP4 to MP3 converter. It requires only a simple few clicks to convert the needed video to MP3. And similar to Convertio, you can upload the video file from your local drive, Dropbox, Google Drive, or URL. What’s special about Online-Convert is that you can also alter the audio parameters before conversion, such as changing audio bitrate, reducing audio channels, trimming audio, and more, so that you can have a customized music file. One thing merit attention is that Online-Convert only accepts files under 100MB size and limits conversions to 20 times per day. And for free users, the conversion will proceed only at a medium speed.

12. Zamzar

Zamzar is a browser-based app that requires no software downloads and installation. It works for all platforms and brings users great convenience when it comes to multimedia conversions, video to audio conversion included. It’s very easy to use Zamzar as the three-step process on its home page will lead you right to the end of the conversion. But make sure you only upload files smaller than 50MB, or it won’t convert the file. It also has a relatively slow conversion speed. So it is suggested that you leave your email on the site so that Zamzar can inform you when the conversion is done.

13. Free File Converter

Free File Converter is one of the best free online MP4 to MP3 converters to take care of your video to audio conversion at a fast speed, for it supports five concurrent conversions (But you have to make sure all the input files have the same format to activate batch conversion mode; also keep the combined files under 300MB). Like many other online converters, you can convert to MP3 from your local file, cloud, or URL. And the conversion will take place in a very smooth manner. Try Free File Converter, and you won’t be disappointed.

14. ConvertFiles

So if you are planning to convert other video formats to MP3 or other audio formats, this is not the site for you. However, if MP4 to MP3 conversion is all you want, MP3Toolbox is the easy and quick solution.
