Step 2

List view.

Change your iTunes view to list view (optional).


Step 3

Song selection.

Locate the song from which you want to make a ringtone.

Step 4

Time selection.

Listen to the song and note the time window you want for your ringtone in seconds, for example, 00:30-00:40.


Step 5

Select and highlight the song with your mouse.

Step 6

Get to the relevant file information as follows: Click "File > Get Info" (in Windows) or Ctrl+click on the individual file on a Mac and select "Get Info" from the drop-down menu.


Step 7

Options menu.

Click "Options" from the menu bar in the window just opened.

Step 8

Start/Stop Time selection in the Options menu.

Check the boxes for "Start Time" and "Stop Time," insert the times you noted in Step 4 and click "OK."


Step 9

AAC version.

Right-click on the song in the list view. Click "Create AAC Version." This will create a copy of the file within the specified time limits from Step 8.

Step 10

Show in Finder.

Right-click on the copied AAC version you just made. Click "Show in Finder" (for Macs) or "Find Location" (or similar) for Windows. If you do not have this option, you can find the file by looking in your iTunes folder that holds the rest of your music. This will open up a new window with the file location.


Step 11

File extensions.

Find the .m4a file and double-click to rename it. (Alternatively, you can right-click (Windows) or Ctrl+click (Mac) and click "Rename.")

Step 12

File extension popup window.

Change the .m4a to .m4r and click "Enter." You will be asked if you would like to replace the file extension. Click "OK." You have now successfully converted your .m4a to an .m4r, ready for syncing with your iPhone.
