All free tools 100% Browser-Based • No Files Stored

WebRTC P2P File Share

Send and receive files directly between devices with peer-to-peer WebRTC encryption. No file size limits, no server storage, and instant auto-join links.

DIRECT PEER-TO-PEER TRANSFER

Transfer files securely

WebRTC P2P

Create a private, temporary room. You will receive a 6-character room code and an auto-join URL to send to your recipient.

100% browser-based transfer. Files are transferred directly between devices using an encrypted WebRTC DataChannel. VPSLake never sees, handles, or stores your files on any server.

HOW TO USE IT

Direct P2P transfer in four steps

Transfer documents, images, videos, and archives directly between browsers without uploading to third-party cloud storage.

  1. 1

    Create a private room

    Select Create Secure Room to generate a unique 6-character room code and an auto-join URL in your browser.

  2. 2

    Share the link or code

    Send the generated link or room code to the recipient via your preferred messaging app or email.

  3. 3

    Peer auto-joins

    When the recipient opens the link, their browser automatically connects to your room via an encrypted WebRTC handshake.

  4. 4

    Drag, drop, and transfer

    Drop files into the transfer zone. Files stream directly between devices with real-time speed and progress tracking.

How WebRTC P2P sharing works

WebRTC (Web Real-Time Communication) is a modern browser standard that allows two web browsers to establish a direct, encrypted socket connection without an intermediary server relaying data.

When you create a room, a temporary signaling handshake exchanges connection metadata (SDP offer and ICE network candidates). Once the connection is established, all files are sliced into binary chunks and sent directly through the RTCDataChannel with DTLS/SCTP encryption.

Zero cloud storage advantages

Traditional file sharing services require uploading files to a cloud server first, waiting for processing, and then having the recipient download from that server. WebRTC eliminates the middleman entirely:

  • Zero cloud storage: Files never touch any server disk or cloud database.
  • No arbitrary file caps: Transfer large videos, databases, or disk images directly.
  • Local network gigabit speeds: Devices on the same Wi-Fi transfer at local LAN speeds.
  • End-to-end encrypted: Built-in DTLS encryption secures the transfer channel.

Safe file sharing advice

Only share room codes and links with people you trust. Because transfers are direct and unmoderated, always verify incoming files before opening executable programs or unknown archives. Both devices must keep the browser tab open until transfers reach 100%.

FREQUENTLY ASKED QUESTIONS

WebRTC File Share FAQ

No. VPSLake servers never receive, store, or process your files. All file slicing, encryption, and transmission occur 100% inside your web browser via direct peer-to-peer WebRTC data channels.
There is no arbitrary file size limit. Files are streamed in 64 KB binary chunks with backpressure memory management. Transfer speeds and memory usage depend only on your device RAM and network bandwidth.
When a user visits a share link containing ?room=CODE, the browser client immediately detects the room code, auto-populates the input, and initiates the WebRTC connection handshake automatically without requiring manual typing.
Yes. Because WebRTC is a direct peer-to-peer connection between browsers without a cloud storage intermediary, both the sender and receiver must keep the browser tab open until the transfer completes.
All modern web browsers supporting WebRTC and HTML5 File APIs are supported, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, Opera, and mobile browsers on iOS and Android.
Yes. WebRTC DataChannels mandate Datagram Transport Layer Security (DTLS) encryption for all peer-to-peer traffic. No third party or ISP can intercept or read the transferred data in transit.
