How to Convert MPEG-4 to MP3 using FFmpeg

How to Install FFmpeg

1. Go to https://www.ffmpeg.org/download.html.

Depending on your web browser settings, you might need to choose what to do with the file, select a location on your computer where you want to save the file and then click on the Save button to start to download.

3. After the download is finished you will need to unzip the ffmpeg.tar.bz2 file (e.g., ffmpeg-3.4.1.tar.bz2). You can use 7-zip for this.

Now you will have a .tar file (e.g., ffmpeg-3.4.1.tar).

(C:) is usually the drive where Windows is installed and where you can find the Windows, Program Files and Program Files (x86) folders.

FFmpeg is now installed and ready to use.

How to Convert Video to MP3 with FFmpeg

1. Copy or drag your MP4 video file into the bin folder of FFmpeg (e.g., (C:) > ffmpeg > bin).

cd\
