How to transfer files between a phone and computer without a cloud upload

Create a temporary two-device session

Open the transfer tool on the first device and create a random session. The page generates a session code, a share link, and a QR code. On the second device, scan the QR code or enter the code to join.

Random sessions do not require an account. A signed-in user can also use a personal session on two devices with the same account. Each session is designed for one connected peer rather than a public group.

• Use the QR code when moving a file between a phone and computer.
• Use the session link when you can send it privately to the other device.
• Do not publish session links or codes because they act as temporary connection credentials.

Keep both browser pages open during the transfer

The browsers establish a WebRTC data connection while the server coordinates the session. When a direct local-network route is available, the interface can identify the connection as LAN Direct.

This is not an offline drop box. If either browser closes, sleeps, changes networks, or loses connectivity, the peer connection can stop and may need to reconnect before sending continues.

Send files in chunks instead of one fragile upload

The transfer tool divides files into small encrypted chunks. The receiving browser tracks chunk numbers, detects missing pieces, and can request retransmission rather than starting the entire file again.

For a large file, keep both screens awake and avoid switching between Wi-Fi and mobile data. The received file is assembled in the second browser after all required chunks arrive.

Use text sharing for links and short notes

The same session can switch between file transfer and text. This is useful for moving a URL, address, command, or short note between your own devices without installing another messaging app.

Ordinary texts remain in the current tab session. Optional disappearing texts stay in page memory and begin a roughly 30-second countdown when the recipient reveals them, but recipients can still copy or capture what they receive.

Understand the privacy boundary

WebRTC and the application encryption protect the transfer in transit, but this should not be described as complete anonymity or guaranteed deletion. The service still coordinates connections, and the recipient controls the downloaded file after it arrives.

Only transfer files you own or are authorized to share. Do not use the tool for illegal material, private data sent to an untrusted recipient, or files that require permanent audited storage.
