Convert your MP4 to MP3 Online

Videos and audio files are a part of our daily lives. From movies and songs to lectures and podcasts, most of the media we consume comes in formats like MP4 or MP3. Sometimes, however, you don’t need the video part of a file—you only want the audio. That is where converting MP4 to MP3 becomes useful.

This guide will explain everything you need to know about MP4 to MP3 conversion, the benefits, how to use Convertio, and why it is one of the best tools available online.
 

What Is MP4?

MP4, also called MPEG-4 Part 14, is one of the most popular video file formats in the world. It can store video, audio, images, and even subtitles in a single file. That is why you see MP4 used everywhere—from online videos to movies and music clips.
 

The main advantages of MP4 include:

  • High-quality video and audio.

  • Compatibility with almost every device and media player.

  • Efficient compression that reduces file size while keeping quality.
     

However, MP4 can take up a lot of storage space, especially if you only want the audio. For example, if you just need the soundtrack of a movie or a podcast recorded as video, keeping the whole MP4 file is unnecessary. That’s when converting to MP3 helps.
 

What Is MP3?

MP3 stands for MPEG-1 Audio Layer 3. It is a digital audio format known for its small file size and good sound quality. MP3 is one of the most widely used audio formats, supported by almost every device, including phones, computers, and music players.
 

The benefits of MP3 include:

  • Small size: Files are compressed without losing much quality.

  • Universal support: Works with nearly all devices and apps.

  • Easy sharing: Because of its small size, it’s faster to upload and share.
     

When you convert MP4 to MP3, you remove the video and keep only the audio part, which saves space and makes it easier to enjoy music or spoken content on the go.
 

Why Convert MP4 to MP3?

There are many reasons why people prefer to convert MP4 to MP3:
 

  1. Save storage space
    Video files are large. A single MP4 music video might take hundreds of MBs, while the MP3 version could be only a few MBs.
     

  2. Listen on the go
    MP3 files can be played on any device, even older ones that don’t support video.
     

  3. Extract music or soundtracks
    You can keep your favorite songs or sound effects from videos without keeping the entire video.
     

  4. Use for learning
    Students often convert lecture recordings from MP4 to MP3 so they can listen while walking, exercising, or commuting.
     

  5. Better sharing
    Smaller files mean faster uploads and downloads when sharing with friends or colleagues.
     

The Traditional Way vs Online Conversion

Traditionally, you would need to download software, install it, and then convert your files. While this works, it has some drawbacks:
 

  • Software may take up space on your computer.

  • Some programs are complicated to use.

  • Free versions often come with restrictions or watermarks.
     

On the other hand, online conversion with Convertio is much simpler. You don’t need to download or install anything. You only upload your MP4 file, choose MP3 as the output, and download your converted file in seconds. It works directly in your browser.
