Frequently Asked Questions

Is DirectFileTransfer free to use?

Yes, DirectFileTransfer is completely free to use. There are no premium plans, no hidden fees, and no file size limits. You can transfer files of any size directly between devices at no cost.

How secure is DirectFileTransfer?

DirectFileTransfer uses end-to-end encryption with WebRTC technology. Your files never touch our servers — they go directly from one device to the other. 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. The transfer speed depends on your internet connection.

Do I need to create an account?

No, you don't need to create an account or register. Just create a room, share the PIN or link with your peer, and start transferring files instantly.

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.
