I built FileVeil to hide any file inside another file.Use a photo, video, document, audio file, or archive as the cover file. The resulting file still looks and works normally while securely containing encrypted hidden files. Everything runs locally in your browser. No uploads. No servers. AES-256-GCM encryption.Video demo: https://www.youtube.com/watch?v=tcxjIDRZh9sI d love your feedback on the implementation, UX, and real world use cases.
