Although iTune does offer function of converting MP4 to MP3, it has its own advantages and limitations in such aspect. Here comes details:
Super Convenient:If you already use iTunes for your music, the new MP3 is instantly added to your library and ready for your iPhone or playlists.
No Extra Software:It’s built-in, so you don’t need to download anything new.
Easy to Use:The process is simple: import the video, right-click, and select "Create MP3 Version."
Good Enough Quality:The sound quality is perfectly fine for listening on headphones, in the car, or on a speaker.
Extra Steps:Youmustadd the video to your iTunes library first. You can’t just convert a file from your desktop.
Quality Loss:It slightly reduces audio quality because it compresses the audio a second time (this is true for most converters).
No DRM Support:Itcannotconvert copy-protected videos from iTunes Store, Amazon Prime, etc.
Messes Up Your Library:It can leave the original video file in your library, making it cluttered if you don't delete it.
Use iTunes if:You're a casual user who wants a fast, simple way to get audio from a personal video into your Apple music library.
Don't use iTunes if:You need to convert protected videos or are an audiophile who needs the absolute best sound quality. Use a dedicated converter instead.
You can convert Mp3 to MP4 iTunes, but the process is feasible only for a few small sized files and basic conversion. For lossless quality conversions with added features, using a professional tool like Wondershare UniConverter is a good choice. This Windows and Mac based program supports over 1000 formats for conversion in high quality and at super fast speed. MP4 files for extracting audio can be added from your computer or directly from a device. With batch processing, multiple files can be converted at a time. Feature to transfer the processed file to an array of devices is also available.

Download, install and launch Wondershare UniConverter on your Mac system. Add the videos by clicking on the
button under the Converter section. Files can also be added directly from the device or can be simply dragged and dropped.

At the top-right corner, click on the drop-down icon at the Output Format: option, and from the pop-up window, select MP3 as the target format from the Audio list. Also, choose the file quality.

Click on the Start All button to start converting MP4 to MP3 on Windows/Mac without iTunes. The files are saved on your system at the Output folder. You can also find them under the Finished tab.

Tip:Before you even import the file, rename it to exactly what you want the final MP3 to be called. iTunes will use the video file's name for the resulting MP3.
Why:It's much easier to find "My_Awesome_Song.mp3" than "VID_002154.mp3" in your music library later.
Tip:Don't just stick with the default MP3 settings. Go toPreferences > Import Settings and choose a higher bitrate for better quality.
*Standard Quality:192 kbps(good for most people, a balance of quality and file size)
*High Quality:256 kbpsor320 kbps(excellent quality, closer to the original, but larger files)
Why:The default is often 128 kbps, which is lower quality. Setting this once means every future conversion will be at your preferred quality.
Tip:If you only want a 2-minute clip from a 1-hour video, use a free tool like VLC Media Playeror QuickTime Player to trim and export just that segment as a new, shorter MP4 filefirst. Then import that shorter file into iTunes to convert.
Why:iTunes will convert the entire video file. Converting a shorter file is faster and you won't have to split the audio track afterward.
Tip:The converted MP3 might have missing or incorrect info (like the artist, album, or genre).Right-clickthe new MP3 file in your library, selectGet Info, and fill in the details manually.
Why:Well-organized metadata makes it easy to find your music later and ensures it syncs correctly to your iPhone. You can edit multiple songs at once by selecting them all first.
Tip:To immediately locate the converted MP3 file on your computer, right-click on it in your iTunes library and select:
*On Windows: Show in Windows Explorer
*On Mac: Show in Finder
Why:This is the fastest way to copy the file to another location, upload it, or use it in other applications without searching through folders.
Tip:This methodwill not workon videos purchased from iTunes, Amazon Prime Video, or other streaming services. These files have copyright protection (DRM).
Why:Attempting to convert a DRM-protected file will result in an error or a silent, unplayable file. You can only convert personal videos or DRM-free downloads.
Tip:After the conversion is done and you have your MP3 file, you probably don't need the original MP4 video cluttering up your "Movies" section in iTunes.
Why:To delete it, right-click the original MP4 and selectDelete from Library. You can choose to either remove it from just the library or also move the original file to your computer's trash.
Converting MP4 to MP3 using iTunes is straightforward and efficient. By adjusting import settings to use the MP3 encoder, users can quickly create MP3 versions of their files without affecting the originals. However, if you want the conversion result with absolute best sound quality, please choose a trustable dedicated media converter like UniConverter for the best output quality guaranteed.
