Short answer: choose AirDrop when everyone has an iPhone, iPad or Mac; choose LocalSend for a household or team mixing Windows, macOS, Linux, Android and iOS; and use Quick Share with AirDrop only when the Android and Apple devices are among the supported models and software versions.
The three tools do not provide the same kind of connection. AirDrop uses Apple’s Bluetooth Low Energy discovery and peer-to-peer Wi-Fi, LocalSend sends directly across your existing local network, and Quick Share’s AirDrop interoperability is a limited rollout that can involve a 24-hour Google-server download window. Those differences determine privacy, setup effort, compatibility and reliability more than the app names do.
Quick decision: which one should you use?
| Situation | Best first choice | Why it fits | Main caveat |
|---|---|---|---|
| Only iPhone, iPad and Mac devices | AirDrop | Built into Apple operating systems and uses a direct Apple wireless path | Limited to Apple’s ecosystem; visibility settings still matter |
| Windows, Android, Apple and/or Linux devices together | LocalSend | One app is available for all five platforms and can work without internet access or a third-party server | Every device must be on a reachable local network; firewall rules or access-point isolation can block discovery |
| Android phone to iPhone, iPad or Mac | Quick Share with AirDrop, if supported | Provides a native-looking handoff where Google’s compatibility rollout is enabled | Support depends on exact hardware and software; it is not universal |
| Privacy-sensitive transfer while avoiding internet services | LocalSend | No account, login or server is required by its design, and transfers are encrypted over the local network | Your Wi-Fi or wired LAN must be configured correctly |
| Large video or photo transfer | Use the option that both devices support reliably | All three can use fast local wireless links when conditions are good | No comparable first-party benchmark establishes one as universally fastest |
How the three transfer paths differ
LocalSend: an app-to-app local-network transfer
LocalSend is a free, open-source application for securely sharing files and messages with nearby devices over a local network without needing an internet connection. Clients are listed for Windows, macOS, Linux, Android and iOS, giving it the widest stated platform coverage of the three options.
Free tools Windows power users keep installed
One-click scans. No signup required.
After installation, devices discover one another on the same reachable LAN. The file then travels between the devices rather than through a vendor account or cloud-storage service. The project documents TCP and UDP port 53317. A host firewall, a router’s guest-network separation, or access-point (AP) isolation can prevent discovery even when both devices display the same Wi-Fi name.

The official design claims “No account, no login, no servers.” It also describes local Wi-Fi transfers, end-to-end encryption and no bandwidth limits. Those are design claims, not a published comparative speed test, so they should not be read as proof that LocalSend will always be faster than either vendor-native option.
AirDrop: Apple’s direct wireless stack
AirDrop is integrated into Apple operating systems. Apple documents a combination of Bluetooth Low Energy (BLE) for discovery and Apple-created peer-to-peer Wi-Fi for the transfer. Supported iPhone and iPad devices run iOS 7 or later, while supported Mac computers run OS X 10.11 or later.
Because the implementation is tied to Apple platforms, AirDrop is not a general Windows or Linux solution. Its advantage is the absence of a separate app: the Share sheet, Finder and Photos workflows are already part of the operating system. AirDrop defaults to Contacts Only, so a device can appear unavailable when the recipient is not recognized as a contact or when receiving is disabled.

Quick Share and AirDrop interoperability
Google announced on November 20, 2025 that Quick Share interoperability with AirDrop had begun rolling out to the Pixel 10 family, with expansion planned for additional Android devices. Google’s current Pixel help guidance says that sending to an iPhone, iPad or Mac requires a device with Quick Share support for AirDrop.
This is therefore a compatibility feature, not a guarantee that every Android phone can send to every Apple device. Check the exact Android model, operating-system version and Quick Share support before depending on it for an important transfer.

Google documents an Everyone for 10 minutes visibility mode that automatically returns to the previous setting. Transfers between devices using the same Google Account can be auto-accepted. For cross-platform transfers, Google also states that files remain available for download on Google servers for 24 hours. That retention window means this path is not purely local in the same way as LocalSend.
Compatibility by device combination
Apple-only households
AirDrop is the practical default when all participants use supported Apple hardware. It is already present, uses Apple’s peer-to-peer wireless method and avoids asking family members to install and learn a separate application. Check receiving visibility if a person cannot be found: AirDrop’s default is Contacts Only, and the recipient may need to change the setting temporarily when the sender is not an approved contact.
Mixed Windows, macOS, Linux, Android and iOS households
LocalSend is the most consistent single-app choice because clients are listed for all five operating systems. Install the application on each device, connect those devices to the same reachable network, and keep the app available while discovery occurs. This avoids maintaining separate tools for each operating-system pair.
AirDrop cannot fill this role because Apple’s documented implementation is restricted to Apple devices. Quick Share may solve a particular Android-to-Apple pairing, but its AirDrop support depends on approved models and software rather than the operating system names alone.
Android to iPhone, iPad or Mac
First check whether the Android device has Quick Share support for AirDrop. If it does, the native flow may be simpler than installing LocalSend. If it does not, LocalSend remains the broadly supported alternative, provided both devices can join the same LAN.

Privacy, encryption and data retention
What stays local
LocalSend is designed for transfers over your local network without internet access, an account or third-party servers. Its project describes end-to-end encryption for the exchange. The local-network requirement still matters: anyone with access to that network may be able to observe device discovery or attempt to interact with exposed services, so use a network you trust and keep host firewalls enabled except where a rule is needed.
AirDrop’s direct BLE and peer-to-peer Wi-Fi design keeps the transfer within Apple’s wireless exchange rather than routing it through a general cloud-storage account. Receiving visibility is part of the privacy model. Leaving AirDrop broadly discoverable increases convenience but also increases the number of nearby devices that can see an endpoint or send a request.
Quick Share’s documented retention window
Quick Share’s cross-platform flow has a documented 24-hour period during which files remain available for download on Google servers. This is materially different from a transfer that never leaves the local network. It does not automatically mean the feature is unsafe: Google says the interoperability was built with safeguards and independently tested. That statement is a vendor assurance, not a comparative security audit of all three services.
Visibility settings to check
- AirDrop: verify whether receiving is set to Contacts Only, Receiving Off or a broader temporary mode. Contacts Only is the default.
- Quick Share: use Everyone for 10 minutes only for the period needed, because the setting returns automatically to its prior state.
- LocalSend: keep the devices on a trusted LAN and review firewall permissions instead of disabling the firewall globally.
How to send a file with LocalSend
- Install the client on both devices. Use the Windows, macOS, Linux, Android or iOS build appropriate to each device.
- Join the same reachable network. A normal home LAN works. A guest SSID or a network with client/AP isolation may allow internet access while blocking device-to-device traffic.
- Open LocalSend on both devices. Keep each app in the foreground or otherwise available for discovery.
- Allow the required network access. If prompted by the operating system firewall, permit LocalSend on the private or trusted network profile. The project documents TCP and UDP port 53317; a rule that blocks those ports can stop discovery.
- Select the file or folder and choose the receiving device. Confirm the recipient name or device identifier before accepting.
- Accept and verify the destination. Check the received file’s size and, for important archives or videos, open it before deleting the original.
If LocalSend cannot see the other device
- Confirm both devices are on the same SSID or wired LAN, not one on a guest network.
- Turn off AP or client isolation for that network, or move both devices to a network that permits local clients to communicate.
- Check that the operating-system firewall allows LocalSend on the current network profile and that TCP/UDP port 53317 is not blocked.
- Disconnect from a VPN or security product that changes local-network routing, then test again.
- Restart LocalSend on both devices after changing network or firewall settings.
Do not buy a new router merely because discovery failed. A router change is relevant only when the current network intentionally isolates clients and you cannot alter that configuration; AirDrop and some Quick Share transfers do not require LocalSend’s LAN discovery path.
How to send with AirDrop
- Enable wireless radios. On the sending and receiving Apple devices, turn on Wi-Fi and Bluetooth. Personal Hotspot can interfere with the expected peer-to-peer path, so disable it if AirDrop is unavailable.
- Set receiving visibility. Open Control Center, press and hold the connectivity controls, choose AirDrop, then select Contacts Only or the broader option when appropriate. On a Mac, use Finder’s AirDrop view and its receiving setting.
- Choose the content. In Photos, Files or another app, tap or click Share and select AirDrop.
- Select the recipient. The recipient accepts the prompt. When Contacts Only is active, ensure the sender is represented correctly in the recipient’s contacts.
- Confirm completion. The receiving app or destination should show the item; large transfers can take time even though the handoff is direct.
AirDrop is the lowest-friction option inside Apple’s ecosystem, but its convenience can hide a visibility problem. If the recipient does not appear, check receiving mode, Bluetooth and Wi-Fi before assuming the file or account is at fault.

How Quick Share to AirDrop works when supported
- Verify support first. Confirm that the Android model and software explicitly support Quick Share for AirDrop. The initial rollout began with Pixel 10 devices on November 20, 2025 and is not universal.
- Prepare the Apple recipient. On the iPhone, iPad or Mac, enable AirDrop receiving. The recipient may need the broader Everyone for 10 minutes mode for the Android device to find it.
- Use Quick Share on Android. Select the file, open the share action and choose the nearby Apple recipient when it appears.
- Accept on the Apple device. Follow the AirDrop prompt. If both devices use the same Google Account where applicable, Google documents that transfers can be auto-accepted; this does not remove the need to verify the destination.
- Allow for the documented download window. Cross-platform files can remain available on Google servers for 24 hours, so treat the transfer as a service-assisted exchange rather than a strictly local handoff.
If the Apple device never appears, confirm the exact model and software support before changing router settings. Unsupported hardware cannot be fixed by placing both phones on the same Wi-Fi network.
Which is fastest for large videos?
There is no comparable first-party benchmark covering LocalSend, AirDrop and Quick Share under the same phone models, network, file size and radio conditions. It is therefore not defensible to declare one universally fastest.
Actual time depends on the devices’ Wi-Fi generation, signal strength, interference, distance, storage speed, file size and whether the path is direct or relayed. LocalSend can use the speed of a good local Wi-Fi network, while AirDrop uses Apple’s peer-to-peer Wi-Fi. Quick Share’s cross-platform path may involve its documented server availability window, so its user-visible performance can depend on more than the local radio link.
For a practical comparison, send the same large file from the same source and destination several times, record elapsed time and verify the resulting file. Treat that as a local network observation, not a universal ranking.
Common failure modes and the right fix
“The other device is not listed.”
For LocalSend, investigate LAN reachability, guest-network isolation, firewall permissions and port 53317. For AirDrop, check Wi-Fi, Bluetooth and receiving visibility. For Quick Share, check supported model and software first; proximity alone does not create compatibility.

“The transfer request is rejected or never appears.”
A recipient may have receiving disabled or restricted to contacts. Temporarily use the appropriate visibility mode, complete the transfer, then restore the more restrictive setting. On LocalSend, make sure the recipient has the app open and has allowed the operating system’s network prompt.
“It works at home but not on the office or hotel network.”
Managed networks commonly separate clients or block peer-to-peer traffic. LocalSend requires a LAN that permits device-to-device communication. Ask the network administrator for an approved private network or use a permitted alternative; do not bypass organizational controls by disabling security software.
“I need to send from Android to Apple, but Quick Share is unavailable.”
Use LocalSend if both devices can join the same reachable LAN. It is the broadest stated cross-platform option and does not depend on the limited Quick Share-to-AirDrop rollout.

Bottom line for different readers
For an Apple-only household, AirDrop is the clear convenience winner because nothing extra must be installed and the transfer uses Apple’s integrated wireless stack.
For a mixed household, school lab or small team that includes Windows, Linux, Android and Apple devices, LocalSend is the strongest general recommendation. It covers all five stated platforms and keeps transfers on a reachable local network without requiring an account, internet access or third-party server.
For Android-to-Apple sharing, Quick Share can be elegant when the exact devices support AirDrop interoperability, but the rollout is model- and software-dependent. Verify compatibility before relying on it, and remember that Google documents a 24-hour server availability period for cross-platform files. When support is absent or privacy requires a strictly local path, use LocalSend instead.
