When someone shares something with you using AirDrop, you see an alert with a preview. You can tap Accept or Decline.

If you tap Accept, the AirDrop will come through within the same app it was sent from. For example, photos appear in the Photos app and websites open in Safari. App links open in the App Store so you can download or purchase the app.

If you AirDrop something to yourself, like a photo from your iPhone to your Mac, you won't see an option to Accept or Decline — it'll automatically get sent to your device. Just make sure that both devices are signed in with the same Apple ID.
