How it works

From open tab to transferred file or text

Six steps, no technical knowledge required.

Direct or relay? Jump to how the connection works ↓

  1. 01

    Open FileTransferX

    Go to filetransferx.com in any modern browser. No install needed — direct transfers work without an account.

  2. 02

    Choose what to send

    Pick Files or Text, then Send on the device that has them and Receive on the device that should get them.

  3. 03

    Add your files or message

    On the sending device, drag files in or choose them and review the list, or type or paste a short message. Nothing is sent yet.

  4. 04

    Connect Devices

    The sender gets a QR code and a short transfer code. The receiver scans the code or types it in.

  5. 05

    Transfer

    Once connected, files move in chunks with a live progress bar, speed and estimated time remaining. A text message arrives the moment it is sent.

  6. 06

    Receive

    The receiving device reviews incoming files and chooses to accept before anything downloads. A text message simply appears on the screen.

Direct or relay: how your files travel

Once paired, FileTransferX always tries a direct connection first. It tries twice before asking anyone to cover a relay, and a relay is used only when your network blocks a direct path.

Direct

The default

  • Files go straight from one device to the other, with no server carrying the file data.
  • Always free, and no account is needed.
  • What you usually get between two Wi-Fi networks.

Relay

The fallback

  • Used only when no direct path can be found. The encrypted file data passes through a secure relay server in transit.
  • A relay runs on paid bandwidth, so one person covers it: the sender, the receiver, or both 50/50, using a free account and its one-time relay allowance.
  • Text transfers stay free over a relay, with no account.

Which one will I get?

Wi-Fi to Wi-FiUsually direct
Home and office routers usually let two devices find each other, so the file goes straight across.
A phone on mobile dataRelay more often
Many carriers put phones behind a shared network address, which often stops a direct connection from forming. It depends on your carrier and your signal, and the same two devices can connect directly one time and need a relay the next.

Pairing: QR code or short code

Every send session generates two things that represent the same temporary transfer: a QR code and a short, human-friendly code such as X7K9-P2M4. A QR code is fastest when a phone is receiving, since it can just scan the sender's screen. A typed code is more practical between two computers, where scanning isn't an option. Both always work, so you're never stuck without a camera. Codes are short-lived and tied to a single transfer session — they are not accounts or permanent identifiers.

Sending text instead of a file

The same pairing and the same direct connection also power Transfer Text, a companion tool for sending a short message device to device rather than a file. Choose Send Text or Receive Text, pair with a QR code or short code exactly as above, and the message appears on the other device the moment it is sent. It is meant for the things that are quicker to beam across than to retype — a Wi-Fi password, a one-time verification code, a link — and, like a file transfer, nothing is stored and closing the tab clears the session.
