Converting MP4 to MP3: The Ultimate Step-by-Step Guide for Beginners

Hello and welcome! In this comprehensive guide, I will teach you how to easily convert your MP4 video files into the universal MP3 music format.

Being able to encode media between different formats is an essential digital skill. However, with so many methods and technical considerations, the process can quickly become overwhelming.

Not to worry! By the end, you‘ll have all the knowledge needed to quickly and flawlessly convert your MP4 library into high quality, compatible MP3s.

Here is an outline of everything we will cover:

  • What are MP4 and MP3 file formats?
  • Key reasons for converting videos to audio
  • 6 simple step-by-step methods to convert files
  • Pro tips for choosing the best technique

Let‘s get started! This guide assumes you have some basic experience using media applications and audio formats.

Understanding MP4 and MP3 File Formats

Before jumping into conversion methods, it helps to understand what exactly MP4 and MP3 files are under the hood.

A Closer Look at MP4 Files

MP4 refers to MPEG-4 Part 14, a digital multimedia format that can store video, audio, subtitles, images, and other data (1).

Here are a few key facts about MP4s:

  • Uses advanced compression for smaller files
  • Container for multiple audio, video and image formats
  • Ubiquitous support across devices and web
  • Customizable resolution, bitrates and quality

MP4 leverages modern video and audio encoding (such as H.264 video and AAC audio) to balance high quality and compact file sizes. This makes it one of the most versatile and portable video formats available today.

YouTube, Facebook, Vimeo and other streaming platforms default to MP4 videos for this reason.

Inside MP3 Digital Audio Files

MP3 stands for MPEG-1/2 Audio Layer III. It revolutionized music compression, reducing file size by over 90% with minimal quality loss (2).

Some details on the MP3 format:

  • Audio-only format compressed up to 1/10th the size
  • Default digital music format supported everywhere
  • Some auditory details lost during compression
  • Bitrates ranging from 128 to 320 kbps

Owing to the small format retaining most music fidelity, MP3 became the standard for digital music distribution and consumption. Virtually every digital device and app supports playback of MP3 audio out of the box.

Now that you understand these formats, let‘s explore why converting video to audio matters.

Why Convert Your MP4 Media Files to MP3s?

There are 3 main reasons for extracting the audio track from MP4 videos and saving to MP3 format:

1. Universal Device Support

Since MP3 is the default audio format across hardware and software media players, converting your MP4 files enables compatibility with more gadgets. You‘ll be able to play the audio from smartphones and speakers to desktop apps without fuss.

2. Save up to 90% of File Size

MP3 compressed audio consumes substantially less storage space. For 4+ minute songs, MP3s average under 5 MB versus MP4‘s 60+ MB for the same video track (3). This matters when dealing with limited device capacity or bandwidth.

3. Audio Quality Enhancements

Stripping and encoding purely the audio contents into an optimized MP3 compression profile can potentially enhance the listening experience. You have more control fine tuning options during conversion.

Now let‘s explore step-by-step methods to achieve seamless MP4 to MP3 conversion using software you likely already own.

Method #1 – Converting MP4 to MP3 with iTunes

For Apple ecosystem users, iTunes offers built-in encoding to get the job done simply:

What you‘ll need:

-macOS computer

-iTunes app

-MP4 video file

Steps to convert:

  1. Launch iTunes on your Mac
  2. Open your MP4 video file using QuickTime Player
  3. Go to File > Export As and save result as M4A format
  4. In iTunes Preferences > General, set Import Using dropbox to MP3 Encoder
  5. Drag newly saved M4A into iTunes library
  6. Right click file and select Create MP3 Version
  7. Find the converted file under Music library and Finder

The MP3 audio output retains near CD-quality sound while consuming much less space.

Pros of Using iTunes:
