How to Sync Ringtones on an iPhone
Adding ring tones to your iPhone works exactly like adding other media -- add the ring tones to your iTunes 12 library, connect your iPhone to your computer and sync. The ring tones must be in the M4R file format for iTunes and your iPhone to recognize them as such.
Launch iTunes and connect your iPhone to your computer. If you haven't already loaded your ring tones into iTunes, click "File," select "Add File to Library," navigate to the location of the ring tones on your hard drive, select them and click "Open" to add your ring tones to iTunes.
Click the "More" button, marked with three dots, and select "Tones" to show the ring tone section of your iTunes library.
Select the ring tones you want to sync to your iPhone.
Click and drag the ring tones, which displays a Devices column. Drag the ring tones over to the entry for your iPhone and release the mouse button to begin the sync process.
Tips & Warnings
- If your ring tones aren't in the M4R format, you can convert them using iTunes (see Resources). You can also create ring tones yourself from any DRM-free music files in your library.
- To automatically sync ring tones whenever your iPhone is connected, click the iPhone icon in the top bar, select "Tones," enable the "Sync Tones" check box and adjust the options to your liking. If you sync some ring tones manually as described in the article, iTunes automatically enables syncing just for the ring tones you synced.
- If you've purchased ring tones from the iTunes store on your iPhone, connect your iPhone to your computer and wait for its icon to appear in iTunes. Click "File," hover over "Devices" and select "Transfer Purchases from iPhone" to copy them to iTunes. This also transfers any other content you've purchased from the iTunes store on your iPhone, such as music or movies -- this works only if you are signed in to iTunes using the same Apple ID you used to make the purchases on your iPhone.
