To transfer photos from iPhone to a laptop via Bluetooth, first of all, you need to make sure the Bluetooth option is turned on for your laptop.
On your laptop, go to Start and click Settings. Open Devices and see if there’s a Bluetooth option. Turn it on.
Note: If you see this option, your laptop doesn’t support Bluetooth. Go to Amazon and search for a Bluetooth adapter for your Windows laptop.
Next, turn on Bluetooth on your iPhone and pair your iPhone to the laptop. Start to transfer photos from your iPhone to the laptop then.
