how to convert itunes mp4 to mp3

MP4 file is video file. If your MP4 video was purchased from iTunes store, it will have DRM protection, you cannot convert it to audio MP3. If your video has no DRM, there are many online apps can do the file conversion for you, such as zamzar, Acethinker Video Converter, mediaconverter, etc. They are totally free, and you don't have to download or install anything. Take Acethinker as sample, here are the steps.

1. Launch your web browser and go to Acethinker Online Converter, you can google search for it.
2. Click ‘select files to start’, and then drag and drop your MP4 video into the app.
3. Click the Format drop down list, select MP3 as output format.
4. Click the Convert button, the App will ask you where to save the converted file.
5. Click Start the run the conversion, it will take a few minutes to finish the task. When the conversion done, you will find the converted file in the folder you set in step 4. Done.

MP4 is video. You cannot convert video to an audio only format. What are you trying to achieve?

You can convert mp4 files to audio. Simply enter Quick Time player and go File>Export>Slect Audio Only. It should become mp3 files.

Hope this helps.

Likely he meant m4r to make a ringtone

See the references at the bottom of here for how to do that.

So I'm being exact. You cannot "convert" a video file (with audio), to audio only.

You can extract the audio, or record the audio into an audio programme etc. as a way of obtaining the audio only. But convert... no.

I answered the question. I also asked the OP to give further information, so that we could possibly provide a suitable solution. After all, as lllaass has suggested, perhaps the OP wants to make a ringtone.

Okay, but isn't it kind of the same thing because he ends up with the file anyway?

No.

I've got iTunes 11.0.3 and couldn't find an option in Quick Time to export the audio from some mp4 files I'd like to listen to without the video. Any suggestions?

Thanks!

You can Google for more: extract audio from video

Crazy! This lead to the trick. I just had to hold "option" while selecting "create new file" under the file tab. A little different from what's out there but it worked! THANKS

Why are you replying to a 4 year old posting?

The OP got their answer.
