Free MP4 MP3 Converter extracts audio from MPEG-4 files and converts them to MP3s.

A simple user interface and a streamlined focus work in favor of Free MP4 MP3 Converter. This program knows exactly what it wants to do and does it well. There are a number of reasons to convert MP4 to MP3, such as using the audio from your MP4s on MP3 players and other devices. To be precise, this utility doesn't directly convert MP4s to MP3s. What it does is extract audio files from MPEG Layer-4 files and convert those to MPEG Layer-3 files.

With Free MP4 MP3 Converter, converting an MP4 to MP3 can happen in as little as two clicks. The app has a default configuration that will be fine in most cases, and it creates the new file while leaving the original MP4 intact. If you prefer, you can configure it yourself. There are multiple conversion methods to choose from, and you can set the bit rate or file size. If you select the file size, the program will use a complex algorithm to determine the appropriate bit rate to achieve it.

Free MP4 MP3 Converter also supports configuration profiles. This becomes quite handy when you routinely require a specific set of settings. You may create profiles, save them and load them as needed. The program permits batching, and you can add entire directories to the queue. Queuing supports profiles as well, so add them on a per-file basis or for each batch you add to the queue. Another neat feature is the ability to turn the computer off. That means that you can start your conversion when you go to sleep. The app will shut the computer down when it's finished, and your music will be ready to play in the morning.

The only issue with the application is that it only supports these two formats. It will be the perfect solution for some people. However, you may prefer an all-in-one program if you have many different file formats to convert. It will convert all of them in a single batch.
