How Cross-Domain File Sharing Works

Client-Side Demo: Files stay in your browser (100% private).
Production: Files upload to cloud storage (AWS S3, Firebase, Cloudinary) with CORS enabled.
Technology: Uses FormData + fetch() API to send files to backend server, which stores them and returns a shareable link.
Cross-Domain: Server sets CORS headers (Access-Control-Allow-Origin: *) to allow access from any domain.
