You can copy and paste between the various locations on your iPhone, iPad, and Mac, but this feature can also be performed on Apple devices using the built-in Universal Clipboard.
For example, you can copy a link to a webpage on your iPhone and paste it into Safari on your iPad, copy a picture on your iPad, and paste it into an app on your Mac. Copy and paste text into your Mac app on your iPhone. You can even copy entire files from one Mac to another.
These tricks are due to the continuity feature called handoff, which allows iOS devices and Mac computers to communicate with each other. For this to work, you must enable certain options for all your devices. After that, you can insert the same element as many times as you like, and it works just as smoothly and effectively as on any device.
Keep in mind that the clipboard can only contain one item. If you copy another item on your iPhone, iPad, or Mac, the new item will replace the previous one on the clipboard. Also, the copied content is only available for a short time, so do not wait too long to insert it.
You can use AirDrop or iCloud to sync items between your Mac and your iOS devices. However, the Universal Clipboard can copy and paste content that these other features may not be able to handle.
