Sooner or later every iPhone owner hits the same wall: a large video, a folder of RAW photos, or a file a colleague needs, and the question of how to move it. The default answers — messaging apps and cloud drives — share a trait that's easy to overlook: your file takes a detour through someone else's server, gets compressed along the way (in the case of messengers), and sits there until someone deletes it.
For everyday snapshots that's fine. For anything you care about — or anything private — local transfer is both faster and more private. The good news is that the iPhone has genuinely good options, one built in and three that respect your data. Here they are, with their limits stated plainly.
AirDrop: built in, great, Apple-only
AirDrop is the baseline. It moves files directly over Wi-Fi and Bluetooth between Apple devices, with no cloud hop and no size limit in practice. A big 4K video that would choke a messaging app arrives at full quality in minutes.
Its limits are the interesting part:
- It only works between Apple devices. Your Android-using friend or Windows desktop is out of reach.
- Receiving from strangers is deliberately restricted — newer iOS versions limit the everyone setting to a ten-minute window — which is a reasonable security trade-off, but it adds friction.
- Discoverability occasionally just fails, in the classic wireless way. Everyone has had an AirDrop that refused to find a device sitting a foot away.
When it works, it's the best experience in this list. It just doesn't cover the whole world.
LocalSend: the open-source AirDrop for everything else
LocalSend is a free, open-source app that recreates the AirDrop experience across platforms — iOS, Android, Windows, macOS, and Linux. Both devices run the app, connect over the same local network, and transfer directly to each other. Nothing leaves your network, and since the protocol is open, you're not betting on one company's goodwill.
The trade-offs: both ends need the app installed, transfers need the same local Wi-Fi (hotel and office networks with client isolation can break it), and the interface is functional rather than delightful. For a privacy-focused toolkit, it's the workhorse.
Snapdrop: no install, but a small asterisk
Snapdrop takes a different approach: open the website on both devices, tap your counterpart's icon, send. No app, no account, works across platforms. It feels like magic the first time.
The asterisk: unlike AirDrop and LocalSend, Snapdrop needs a server. The website brokers the introduction between the two devices; the file itself then moves peer-to-peer over WebRTC, so the content doesn't pass through the server, but the fact that two devices are talking does. In practice, the file stays local — the coordination doesn't. If your threat model includes "nobody should even know I transferred something," use LocalSend. If you just don't want your files uploaded, Snapdrop is fine, and it saves you from installing anything on a borrowed device.
USB: the option people forget
A Files app trick hiding in plain sight: plug a USB drive into your iPhone — directly on recent models with USB-C, or via a Lightning adapter on older ones — and it shows up in Files. Copy photos, videos, or documents straight to it. No network, no apps, no accounts, full original quality.
This is genuinely the fastest way to move a hundred gigabytes of video, and it's completely offline. The trade-offs are the hardware: you need the right cable or adapter, the drive needs a compatible file system (exFAT is the safe choice), and it's clunkier than a tap-to-share for a single photo. For small everyday sends, use AirDrop or LocalSend. For bulk, USB wins outright.
The privacy scorecard
- AirDrop: fully local, Apple devices only.
- LocalSend: fully local, everything, open source — the default recommendation.
- Snapdrop: local file path, server-assisted pairing, zero install.
- USB: fully offline, best for large transfers, needs dongles.
For most people the honest answer is: AirDrop within the Apple world, LocalSend everywhere else, USB for the big stuff. All three keep your files on your devices, which is the whole point.
