Use iTunes to Convert Lossless Music Files to AAC or MP3

Sometimes, it’s necessary to convert uncompressed lossless files to an MP3 or AAC format. Or convert files to a lower bitrate to save space. Here’s how to use iTunes to convert your files.

First, open iTunes and go to iTunes > Preferences from the menu bar. If you’re using iTunes for Windows, click Edit > Preferences.

itunes then preferences

Under the General tab, click Import Settings.

Then select the file type you’d like to convert the file to by clicking the drop-down menu next to Import Using.


Next, select the quality you’d like to convert the file to by clicking the drop-down next to Setting.

select quality setting

If you need to use a quality that isn’t listed by default, click on Custom. This is where you can set your own sample rate, Variable Bit Rate, and more.

Now, find the track in your iTunes library you want to convert. If it’s not in your library, you’ll have to add it.

select track to convert

With that track selected, click Advanced in the menu bar, then Convert to MP3 or AAC. The file type you selected in the previous steps is displayed.

When the process is complete, two tracks with the same name will show in your library. To ensure you get the right one, right-click the track and select Get Info. Or highlight the track and hit Command+I on the Mac or Ctrl+I on a Windows keyboard.

Under the Summary tab, you’ll be able to see which file in iTunes is the original and which one you converted. If you want to convert a batch of files, select all the files you’d like converted and then follow the same process.
