Tips to copy-paste images between iPhone and Mac

Universal clipboard is known as the ability to copy items on one Apple device and paste them on another. This works across iOS and macOS devices and is a neat feature to have if you keep switching between your Apple devices.
According to Gadgets 360, the feature works only on iOS 10 and macOS Sierra. So, make sure your devices are accordingly updated.
Here’s how to enable universal clipboard on your iPhone, iPad, and Mac:
Sign in to the same iCloud account on all devices.
On iOS, head to Settings > iCloud to check your iCloud account.
On macOS, open System Preferences > iCloud and check it matches with what you noticed in step 2.
Switch on Bluetooth on all your devices.
On iOS, head to Settings > Bluetooth to do this.
On macOS, open System Preferences > Bluetooth to switch on Bluetooth.
Switch on Wi-Fi on all of your devices
On iOS, head to Settings > Wi-Fi.
On macOS, click the Wi-Fi icon on the top bar.
Once you’ve done all of these things, universal copy-paste should start working. Just copy anything on your iOS devices and paste on your Mac. There are no toggles or switches to enable this. It should start working on its own. You can use this to copy text and images between your iPhone and Mac, though text formatting may not always be preserved, depending upon the apps you are using.
Note that for universal clipboard to work all devices need not be on the same Wi-Fi network, but Wi-Fi and Bluetooth need to be switched on, and the devices need to be close to each other, though Apple doesn’t specify what ‘close’ means. We tested this with a MacBook Air connected to a Wi-Fi network and an iPhone on 4G, and universal copy-paste worked just fine.
