Send anything,
at full Wi-Fi speed.
LanSwift moves files and whole folders between your phone, PC, Mac, Linux box — even a friend's browser — straight over your local network. No internet. No cloud. No cables.
Everything you need.
Nothing you don't.
Built for people who just want files on the other device — fast, private and without fuss.
Direct LAN transfers
Devices talk peer-to-peer over TCP. Your router is the only thing in the middle, so you get real Wi-Fi speed.
Automatic discovery
Nearby devices appear instantly — no IP addresses to type, no pairing codes to remember.
Zero-install web portal
Share a link or QR code. Anyone can send or receive from a plain browser — no app required.
Resumable & reliable
Screen locked or Wi-Fi hiccup? Transfers pick up from the exact byte where they stopped.
Chunk-level integrity
Every 256 KB chunk is verified, so what arrives is bit-for-bit what was sent.
Folders & multi-device
Send entire folders to several devices in parallel, with a live per-file progress view.
Three taps. Done.
No sign-up, no configuration. Just be on the same Wi-Fi.
Connect to the same network
Put both devices on one Wi-Fi or hotspot. Nothing else to set up.
Pick files & a device
Choose files or folders, then tap the device that shows up in the nearby list.
Accept & watch it fly
The receiver accepts and you see live speed, progress and verified chunks.
Pipelined for
maximum throughput.
A streaming engine keeps the network saturated and uses keep-alives and wake-ups so long transfers survive aggressive phone power-saving.
- 256 KB pipelined streaming — no per-chunk round trips.
- Keeps the screen awake only while a transfer is active.
- Auto-resume mid-file after interruptions.
One app. Every device.
Move files between any combination of these — and anything with a browser.
Your files never leave
your network.
No account, no tracking of your files, no servers storing your data. Read our Privacy Policy — it's short and plain.
Questions, answered.
Does LanSwift need internet?
No. Transfers happen directly between devices on your local network. Internet is only used by the optional ads in the app.
Is there a file-size limit?
No. Files are streamed in chunks, so very large videos and folders work fine as long as the receiver has storage.
Are my files uploaded anywhere?
Never. Files go device-to-device. We don't operate servers that see your content.
My transfer stopped when the phone slept — now what?
LanSwift keeps the screen on during active transfers and resumes automatically from the last confirmed byte. For best results, allow the battery-optimization exemption when prompted.
Can someone without the app receive files?
Yes — share the web-portal link or QR code and they can use any modern browser on the same network.
Is LanSwift free?
Yes, it's free and supported by unobtrusive ads.
