Introduction: The Simplest Way to Share Large Files
Sharing files should be simple, but email attachment limits (usually 25MB) and free cloud storage caps make sharing large files difficult. Many users register for multiple services just to send a single folder, which exposes their personal data. Direct peer-to-peer (P2P) file transfer offers a simpler, account-free alternative.
This guide explains how to use our serverless P2P platform to share files of any size quickly, securely, and completely free, without uploading them to third-party servers.
Step 1: Open the Direct Transfer Interface
To begin, open our platform in your web browser. You do not need to register an account, verify your email, or download any software. The entire interface runs locally inside your browser, using modern web standards to prepare and manage your transfer connection.
Step 2: Select Files or Folders of Any Size
Click the file selection area or drag and drop your files directly into the window. Because the system streams data directly from your device storage to the recipient, there are no file size limits. You can select large video files, folder structures, or database backups without zipping them first.
| Transfer Step | Action Required | Technical Event Behind the Scenes |
|---|---|---|
| 1. Add Files | Drag and drop files or directories into the browser. | File handles are opened locally; no data is uploaded. |
| 2. Copy Link | Copy the unique generated sharing link. | AES-256-GCM keys are created in the browser hash. |
| 3. Connect | Send the link to the receiver; they open it in their browser. | WebRTC coordinates a direct peer-to-peer connection. |
| 4. Stream | Keep both browser tabs open until the transfer completes. | Data streams directly between devices, encrypted end-to-end. |
Step 3: Share the Generated Link
Once you select your files, the platform generates a unique sharing link. This link contains the connection parameters and a client-side decryption key. Copy this link and send it to your recipient via your preferred messaging or email platform. The key is in the URL hash, meaning it remains local to your device and is not shared with our signaling server.
Step 4: Keep the Browser Tabs Open
When the recipient opens the link, a direct WebRTC connection is established between your browsers. The transfer begins immediately. Because this is a direct peer-to-peer transfer, you must keep both browser tabs open until the progress bar reaches 100%. Once complete, the recipient has the exact file saved to their device.
Security: E2EE Client-Side Encryption
Your privacy is maintained throughout the transfer. Files are encrypted client-side using AES-256-GCM. The decryption key is generated in your browser and appended to the sharing link as a hash parameter. Because the hash is never sent to the signaling server, the keys remain local to your device, ensuring privacy.
Frequently Asked Questions on Direct Transfers
Do I need to install any software?
No. The entire process runs inside modern web browsers using built-in web standards like WebRTC and the Web Crypto API.
Can I close my browser tab during the transfer?
No. Because the transfer is direct between devices, both the sender and receiver must keep their browser tabs open until the transfer completes.
Is there a limit on the number of files?
No. You can add as many files or folders as you need. The platform handles the batch queue automatically in your browser.
How secure are my files?
All files are encrypted client-side using AES-256-GCM. The decryption key remains in the URL hash and is not shared with the server.
