Q: How do i backup voice memos from my iphone to my mac or ipad

Greetings CyndeLeon,

If you want to back up items on your iPhone, you can use either iCloud or iTunes on your computer. See this article for information about backups of iOS devices -

About backups in iCloud and iTunes - Apple Support

Note that voice memos from an iPhone can not be restored to a different type of iOS device such as an iPad.

If you want access to those voice memos when they are on the computer, however, you need to sync the iPhone with your computer. See this article for how to do so -

Sync your iPhone, iPad, and iPod with iTunes using USB - Apple Support

The voice memos will then be available in iTunes on the computer.

Thanks for using Apple Support Communities.

Be well,

Brett L
