Convert MP4 to MP3

Thanks for the sarcasm mate but it works for me Chris. I'm using OS X Yosemite version 10.10.15 . I think you are making things way to complicated. It's easy, it works and takes a minute.

No it does not.

Changing the file extension does NOT convert the file to MP3.

Doesn’t matter which OS you are using (Windows, Mac, Unix, etc) , It has never done this.

But the users want to actually convert songs to MP3, not simply change the file extension which does nothing (except confuse the OS).

Do you really think you discovered something that no one, including Apple, knows exists?

It's easy to demonstrate that it doesn't. Here is the 'Movie Inspector' pane in the QuickTime X player for an MP4 file where I have used your method to change the extension to MP3. As you will see the actual format remains unchanged - a test you can easily carry out on your own files.

I just had this problem. & I figured it out. What you do... If you got a new computer (like me) and in Itunes it has ACC files on your songs.,. You first do Prefences > import settings> and change it to the "MP3 encoder." THEN, you hit ok > ok > see in your music library, by all of the songs there will be a cloud like emoji with a arrow pointing down on it. You will click that, and it'll start to download. Once it's done, you can right click on the song, and you will see "Create MP3 version." and it should pop up another file, the ACC file will still be there. The MP3 one will be MPEG file. As far as I know you have to do each song individually, once you create them into MP3 versions you plug in your device, you click and drag the song to the device, or just right-click copy > & paste the song in the file of device. I hope this made sense to someone, and I could help!! 🙂

thank you! works perfectly. now the painstaking task of converting album by album.

For the people who look for a way of converting video MP4 files to MP3 files just by using the stock applications in a Mac, here's what works for me: convert the MP4 video file to an Apple audio-only file by using QuickTime Player and convert the Apple audio-only file to an MP3 audio file by using iTunes.

If you are a long time user of a Mac the above should be enough, otherwise here are the detailed steps to do this on Mavericks with QuickTime Player 10.3 (727.4) and iTunes 12.3.2.25 (don't be put off by the number of words required to write them, to do it is rather simple):

1) first convert the video file to an audio-only file by using QuickTime Player:

* open Finder and go to the folder where your file is located and double-click your video MP4 file and QuickTime Player will open it (if your default video player is different than QuickTime Player just open QuickTime Player and open your video MP4 file in it)

* go to File > Export > Audio only... and a window will open allowing you to change the name of the file and to choose the location where your audio-only file will be stored; set the desired file name and location for it and press the Save button -> this will create an "Apple MPEG-4 Audio" file that has the extension "m4a" -> if you use the Finder to visualize it, the file will be displayed just with its name and the Type column will show it as "Apple MPEG-4 Audio" -> select the file, right-click it and choose Show Information from the pop-up menu and you will see its name and the "m4a" extension

2) convert the audio-only file to MP3 using iTunes

* in iTunes, go to iTunes / Settings (or press Command and ,) and the iTunes settings window will open with the General pane fields; if the General pane is not selected, click on it -> click the Import Settings in the section at the bottom of the pane -> the Import settings window is shown and select "MP3 Encoder" in the drop-down for the first field in the window and the desired audio quality in the second field, finally press the OK button -> now you're back to the General pane and press the OK button

* in Finder, double-click your converted "Apple MPEG-4 Audio" file (created at the step 1) above) and iTunes will open it and start playing it; if this does not happen, open iTunes manually and then drag the audio file from the Finder window into iTunes;

* in iTunes, if you do not see your file (even if you hear it playing), go to View / Music (or press Command and 1) and then click on Playlist -> this should now display the Recently Added Items list at the top of the window with your audio file shown as the first item in it -> click on your file and then right-click on your file and click on "Create MP3 version" option in the shown drop down -> you should now see one more file with the same name as your audio file in the first position of the Recently Added Items list: this is the desired MP3 file -> to confirm this, click on it and the right-click on it and click on "Display Information" option in the shown drop down -> then click on the File tab and look down at the last field on the tab that shows the location of the file with its name and extension

You are a genius this worked perfectly!!!! Thank you thank you - muwahhhhhh

Thanks to everyone else who chimed in and helped - very much appreciated.

If you are listening to a music video, but the file shows in the "movie" app on your device, then I suggest you go to itunes, find the file, right click>get info>options>media kind>music video

That way, when syncing with your device, the file will be in your music library as a video, but function the same as other mp3. files.

And the Mac keyboard has no Windows key, only a page-up key.
