This list includes formats for audio books and podcasts.
iPhone supports video files in the following formats: H.264 (Baseline Profile Level 3.0), MPEG-4 (Simple Profile).
A song encoded in Apple Lossless format has CD sound quality, but takes up only half the space compared to a song in .aiff or .wav format. The same song in .aac or .mp3 format takes up even less space. When you import music from a CD using iTunes, the material is converted to .aac format by default.
Using iTunes for Windows, you can convert unprotected .wma files to .aac or .mp3 format. This function is of interest when there is data encoded in the .wma format in the library.
iPhone does not support .wma, MPEG Layer 1, MPEG Layer 2, and audible.com 1 audio files.
If your iTunes library has songs or videos that are not supported by iPhone, you can convert them to a format that iPhone supports. For more information, see iTunes Help.

Backup

Backups can be created in the following ways:
- After the iPhone is configured to sync with a specific computer, iTunes automatically backs up the iPhone on that computer during synchronization. iTunes does not automatically back up an iPhone device that is not configured to sync with this computer. If you set up your iPhone to automatically sync with iTunes on a specific computer, iTunes will back up your iPhone every time you connect it to your computer. Auto sync is enabled by default. iTunes only creates one backup each time the device is connected, even if the synchronization was performed several times before disconnecting.
- If you decide to update the software on your iPhone, iTunes will automatically back up your iPhone, even if it is not configured to sync with iTunes on this computer.
- If you decide to restore the iPhone software, iTunes will ask you to back up your iPhone before recovery. If you are using a Bluetooth headset or car kit with your iPhone and you are restoring the setting, you must reconfigure it to pair with the iPhone to use the Bluetooth device.

Restore from backup

You can restore settings, downloaded programs, and other information from a backup, or use this feature to transfer these items to another iPhone. For this:
- Connect the iPhone to the computer with which synchronization is usually performed.
- In the iTunes side menu, select iPhone and select the Browse tab.
- Select Restore to reinstall the iPhone software, restore the default settings, and delete the data stored on the iPhone. In iTunes, you can also restore from backups without deleting data stored on iPhone.
Deleted data becomes inaccessible through the iPhone user interface, but it is not completely erased from the iPhone until it is replaced by new data. When prompted, select the option to restore settings, downloaded programs, and other information from the backup, and select the backup you want to use. Several backups are listed separately for each device in chronological order, the most recent backups being the first in the list.

Delete backup

You can delete your iPhone backup from the backup list in iTunes. This may be required, for example, if a backup was created on another user's computer. For this:
- In iTunes, open iTunes settings. For Windows, select: Edit / Settings. For Mac, select iTunes / Preferences.
- Select “Devices” (iPhone connection not required).
- Select the backup you want to delete and click "Delete Backup".
- Confirm the deletion of the selected backup by clicking “Delete backup”.
- Click OK to close the iTunes settings window.

IPhone software update and recovery

You can use iTunes to update or reinstall iPhone software, restore default settings, and delete all iPhone data. If you update the iPhone, your software is updated, but downloaded programs, settings, and songs are not affected. When restoring, the newest version of the iPhone software is restored, the default settings are restored, and data stored on the iPhone is deleted, including downloaded programs, songs, videos, contacts, photos, calendar information and all other data. In iTunes, you can also restore from backups without deleting data stored on iPhone. Deleted data becomes inaccessible through the iPhone user interface, but it is not completely erased from the iPhone until it is replaced by new data.
