Frequently Asked Questions

Is DirectFileTransfer free to use?

Nearby and same-Wi-Fi transfers are free forever, unlimited, at full speed. Sending over the internet is free up to a monthly allowance; DFT Pro raises it. No hidden fees, no file size limits.

How secure is DirectFileTransfer?

DirectFileTransfer uses end-to-end encryption with WebRTC technology. Your files go directly from one device to the other and are never stored on or readable by our servers; when a network blocks every direct path, an encrypted relay carries the bytes it cannot decrypt. The connection is secured with DTLS encryption (256-bit AES-GCM). We also support password-protected rooms for an extra layer of security.

What is the maximum file size I can transfer?

There is no maximum file size limit. Since files transfer directly between devices, you can send files of any size. Sending over the internet has a monthly data allowance on the free plan.

Do I need to create an account?

Not to start. Create a room, share the PIN or link with your peer, and transfer instantly. Signing in with Google is optional and only unlocks reaching your own devices and friends over the internet.

How does device-to-device file transfer work?

DirectFileTransfer uses WebRTC technology to establish a direct encrypted connection between your browser and the recipient's browser. Files are sent directly from one device to the other, bypassing any cloud storage or servers.

What's the difference between sharing a Link vs PIN?

Both options create the same direct connection. The Link is a URL you can share via any messaging app, while the PIN is an 8-digit code they type on our homepage. Links offer convenience; PINs work well when dictating over phone calls.

Can I send multiple files at once?

Yes! Select multiple files or drag and drop several at once. They queue and send one after another automatically. The receiver only needs to accept the first file — all subsequent files are auto-accepted.

Do transfers use the internet if both devices are on the same network?

No! When both devices are on the same WiFi or LAN, WebRTC detects this and establishes a direct local connection. Your files never leave your local network — they transfer at LAN speed.

How does DirectFileTransfer compare to other tools?

Most file sharing tools upload your files to a server. DirectFileTransfer sends files directly between devices with end-to-end encryption, multi-file batch transfer, LAN-speed same-network transfers, password protection, and built-in encrypted chat.

What happens if my connection drops during a transfer?

DirectFileTransfer has built-in reconnection support. If your connection drops briefly, the app will attempt to reconnect automatically. For longer disconnections, you can rejoin the room and restart the transfer.

How fast are the transfers?

Speed depends on your connection quality. You can typically expect 1-10 MB/s since direct connections eliminate server bottlenecks. Same-network (LAN) transfers can reach much higher speeds.
