Handoff vs AirDrop: Which Apple Feature to Use

Card No. 06·4867 · Updated · Standard formula, shown below

Handoff and AirDrop are both Apple Continuity features, but they solve different problems: use AirDrop to send files, photos, and links between your own Apple devices or to someone else’s, and use Handoff to pick up work (like an email, document, or web page) on another device right where you left off. This article explains how each works, when to choose one over the other, and answers common questions about both.

What Is Handoff?

Handoff is part of Apple’s Continuity suite that lets you start an activity on one Apple device and continue it on another. For example, you can begin composing an email on your iPhone, then walk over to your Mac and finish it there. Handoff works with Apple’s own apps (Mail, Safari, Pages, Numbers, Keynote, Maps, Messages, Calendar, Reminders, Notes) and many third-party apps that have adopted the feature.

Handoff uses Bluetooth Low Energy (BLE) and Wi-Fi to detect nearby devices signed into the same Apple ID. When you’re near another device, the app icon appears in the Dock (on Mac) or in the App Switcher (on iPhone/iPad). Tap or click it to pick up where you left off. The feature requires:

  • Devices signed in to the same Apple ID with two-factor authentication enabled
  • Bluetooth and Wi-Fi turned on (both devices)
  • Handoff enabled in Settings > General > AirPlay & Handoff on iOS/iPadOS, and System Settings > General > AirDrop & Handoff on macOS
  • Devices within about 30 feet (10 meters) of each other

Handoff does not send a copy of the file; it transfers the state of the activity (the document, the URL, the cursor position) so you can continue seamlessly.

What Is AirDrop?

AirDrop is Apple’s wireless file-transfer protocol that uses Bluetooth to discover nearby devices and Wi-Fi (or peer-to-peer Wi-Fi) to send the data. It works between iPhones, iPads, and Macs, and it does not require an internet connection or email. You can send photos, videos, documents, contacts, map locations, and more.

To use AirDrop:

  1. Turn on Wi-Fi and Bluetooth on both devices.
  2. Open the Share sheet (tap the share icon) and select AirDrop.
  3. Choose the receiving device from the list that appears. The recipient must have AirDrop set to receive from Contacts Only or Everyone.

AirDrop uses encryption (TLS) and requires the devices to be within about 30 feet (10 meters), though the range can be longer in open spaces. It is faster than email for large files and does not compress or degrade the original file.

Key Differences: Handoff vs AirDrop

The core difference is the type of transfer:

  • Handoff transfers the state of an activity, not the file itself. It’s for continuing work.
  • AirDrop transfers the file itself, creating a copy on the receiving device.

Another difference is the recipient. Handoff only works between your own devices (same Apple ID). AirDrop can send to anyone nearby, even if they are not in your contacts (if they set AirDrop to Everyone). AirDrop also works between devices that are not signed into the same Apple ID, making it useful for sharing with friends or colleagues.

Finally, Handoff is instant and automatic—you don’t choose a destination; you just tap the icon. AirDrop requires you to select a recipient and the recipient must accept the transfer (unless you’re sending to your own devices, where you can set “Receiving Off� for unknown people but still receive from your own devices).

When to Use Handoff

Use Handoff when you want to continue an activity on another device. Common scenarios:

  • You start a Safari search on your iPhone and want to read the full article on your Mac’s larger screen.
  • You’re drafting an email on your iPad and need to attach a file from your Mac’s desktop.
  • You’re editing a Pages document on your Mac and need to step out, but you can continue editing on your iPhone while on the go.

Handoff is also useful for phone calls: if your iPhone is in another room, you can answer a call on your Mac or iPad (requires same Apple ID and Wi-Fi). However, that is a separate Continuity feature (iPhone Cellular Calls), not Handoff itself.

Handoff does not work with every app. If the app does not support Handoff, you won’t see the icon. Also, the devices must be relatively close (within Bluetooth range) and have the feature enabled.

When to Use AirDrop

Use AirDrop when you need to transfer a file from one device to another—whether it’s yours or someone else’s. Examples:

  • You took a photo on your iPhone and want it on your Mac without emailing it to yourself.
  • A colleague sends you a PDF via AirDrop during a meeting—no need to exchange email addresses.
  • You have a large video file that is too big for email (AirDrop has no practical size limit, though very large files take time).

AirDrop is also the only way to wirelessly transfer files between an iPhone and a Mac without using iCloud or a cable. It works even if you are not connected to the same Wi-Fi network (it creates a peer-to-peer Wi-Fi connection).

One limitation: AirDrop requires the receiving device to be awake and unlocked (on iOS) or to have AirDrop enabled in the Finder (on macOS). If the recipient’s screen is off or the device is in Sleep, the transfer may fail.

Common Problems and Troubleshooting

Both features can fail if settings are not correct. Here are common issues and fixes:

  • Handoff not showing up: Ensure both devices are signed into the same Apple ID with two-factor authentication, Bluetooth and Wi-Fi are on, and Handoff is enabled in Settings. Also, restart both devices if it still doesn’t appear.
  • AirDrop not finding a device: Check that both devices have Wi-Fi and Bluetooth on, and that AirDrop is set to “Contacts Onlyâ€� or “Everyoneâ€� (not “Receiving Offâ€�). Also, move closer (within 30 feet) and make sure the receiving device is awake.
  • AirDrop says “Unable to Sendâ€�: This can happen if the receiving device is locked or if the file is corrupted. Try again with the screen unlocked, or restart both devices.
  • Handoff works only with Apple apps: Many third-party apps support Handoff, but not all. Check the app’s documentation or look for the Handoff icon in the Dock/App Switcher.

If you are sending to someone who is not in your contacts, they must set AirDrop to “Everyone� temporarily. Apple recommends switching it back to “Contacts Only� after the transfer to avoid unsolicited files.

Handoff vs AirDrop: Which Is Better?

Neither is better overall—they serve different purposes. If you need to continue working on a document, Handoff is the right tool. If you need to share a file, AirDrop is the right tool. In some cases, you might use both: you can AirDrop a file to your Mac, then use Handoff to continue editing it in an app that supports Handoff.

For example, you could AirDrop a PDF from your iPhone to your Mac, then open it in Preview. But if you were reading a web page in Safari, Handoff would let you continue reading on your Mac without sending a file—it just transfers the URL.

There is also a third option: iCloud Drive. If you save a file to iCloud Drive, it syncs across devices automatically, but that requires an internet connection and storage space. AirDrop is faster for one-off transfers, and Handoff is faster for continuing an activity.

Frequently Asked Questions

Can I use Handoff to send a file to someone else?

No. Handoff only works between your own devices signed into the same Apple ID. To send a file to another person, use AirDrop, email, or Messages.

Does AirDrop work without Wi-Fi?

AirDrop uses Bluetooth for discovery and Wi-Fi for the actual transfer. It can create a peer-to-peer Wi-Fi connection, so you don’t need to be on an existing Wi-Fi network, but both devices must have Wi-Fi and Bluetooth turned on.

How do I turn on Handoff on my iPhone?

Go to Settings > General > AirPlay & Handoff and toggle on “Handoff.� On a Mac, go to System Settings > General > AirDrop & Handoff and check “Allow Handoff between this Mac and your iCloud devices.�

Why is AirDrop not working between my iPhone and Mac?

Make sure both devices have Wi-Fi and Bluetooth on, and that AirDrop is set to receive from “Contacts Only� or “Everyone.� Also, check that the Mac has AirDrop enabled in Finder (Go > AirDrop). If it still fails, restart both devices.

Does Handoff use data?

Handoff uses Bluetooth Low Energy and Wi-Fi to transfer the state, not the file content. It does not use your cellular data plan, but it does require both devices to have Wi-Fi and Bluetooth enabled.

Can I AirDrop between an iPhone and an Android phone?

No. AirDrop is proprietary to Apple devices. For cross-platform transfers, use a cloud service, email, or a third-party app like Snapdrop (which works over Wi-Fi but is not an official Apple feature).
