How to Convert MP3 to MP4 With Windows Media Player and FFmpeg

Introduction to MP3 to MP4 Conversion

Converting files from one format to another is a common task in digital media management. MP3 and MP4 are two of the most widely used file formats today, each serving its unique purpose. MP3 is primarily used for audio files due to its high compression and efficient storage, while MP4 is a container format that supports both audio and video streams. You may have encountered the need to convert MP3 to MP4 for various reasons, such as adapting content for specific devices or applications, or fulfilling requirements for certain platforms. In this article, we will explore both the manual and command-line approaches to this conversion process, focusing on their suitability, ease of use, and options available to users.

Using Windows Media Player for Converting MP3 to MP4

Step-by-Step Guide to Convert MP3 to MP4 Using Windows Media Player

While it might seem counterintuitive to convert an audio file (MP3) to a video format (MP4) using a media player, such as Windows Media Player, it is possible. However, this method will merely add a video frame to the MP3 audio, as all video information will be discarded.

Launch Windows Media Player.

Click on File Open…. In the Open dialog that appears, navigate to the location on your computer where the MP4 file you want to convert into an MP3 file is located. Select the MP4 file and click on Open.

Once the target MP4 file is open in Windows Media Player, click on File Save as….

In the Save as dialog, change the file extension from .mp4 to .mp3 by modifying the filename to remove the .mp4 and add .mp3 at the end. This change will not affect the actual content but will help your system recognize it as an MP3 file.

Navigate to the directory where you want the converted MP3 file to be saved and click on Save. Windows Media Player will then begin the conversion process, which is typically quick due to the simple nature of the operation.

For a more professional and robust solution, consider using dedicated software like Any Audio Converter, which is highly regarded and can save you time and effort.
