P2P File Transfer (Browser-Based Demo)

What is P2P File Transfer?

This tool demonstrates a simplified concept of Peer-to-Peer (P2P) file transfer directly within your web browser. Instead of uploading files to a central server and then downloading them, this method encodes your file into a Base64 string. This string can then be shared with another person, who can paste it into their browser to reconstruct and download the original file.

It's important to note that this is a conceptual demonstration and not a robust, secure, or scalable P2P solution for large files or sensitive data. It leverages the browser's ability to handle Data URLs (Base64 encoded data embedded directly in a URL or HTML) to facilitate direct sharing without server intermediaries. This approach is limited by browser memory and URL length constraints, making it suitable only for small files.

The primary benefit of this method is its simplicity and directness for very small files or text snippets. It bypasses traditional upload/download mechanisms, offering a quick way to exchange data between two parties who are both using this tool.

How to Use This Tool

1. To Share a File:
   • Click "Upload File" and select the file you wish to share.
   • The tool will generate a long Base64 encoded string. Copy this entire string.
   • Share this copied string with the recipient (e.g., via chat, email).
2. To Receive a File:
   • Ask the sender for the Base64 encoded string.
   • Paste the received string into the "Paste Received Code Here" text area.
   • Click the "Download File" button. Your browser will then prompt you to download the original file.

Important Security Note: This method is NOT secure for sensitive information. The Base64 encoding is easily reversible, and the data is transmitted in plain text. Only use this tool for non-sensitive, small files.
