How JaldiBhejo Keeps Browser File Sharing Private

JaldiBhejo is built around WebRTC data channels, a browser technology that can create a direct peer-to-peer connection between two devices. The sender creates a transfer room, the receiver joins with a PIN or QR code, and the browser handles the encrypted connection used to move the file.

The signaling server helps both browsers discover each other, but the actual file payload is sent through the browser connection. This keeps the app lightweight and avoids storing your file as a server-side upload.

The six-digit PIN is a short-lived connection code. It is meant to help the receiver join the correct transfer session without creating an account or sharing a permanent link.

For best results, share the PIN only with the person receiving your file and avoid posting it publicly. If a transfer looks wrong, cancel it and start a new one.

JaldiBhejo also includes browser tools such as image compression. These tools run on your device using browser APIs, so the image can be processed without uploading it to a separate conversion server.

This local-first approach is useful for quick preparation before sharing. For example, compressing a large photo before sending it can reduce transfer time and make mobile sharing easier.

Peer-to-peer sharing does not replace common sense. Only accept files from people you trust, check file names before saving, and use your operating system's security tools for files from unknown sources.

When receiving important documents, confirm the sender and the file name outside the app as well. A quick message or call can prevent accidental transfers.
