How Client-Side Processing Works Behind the Scenes
Unlike traditional cloud utilities, ReadyForFile executes all file processing directly within your device’s browser sandbox:
The browser loads your document into local device RAM via the HTML5 File & FileReader API.
High-performance JavaScript / WebAssembly compiles the output locally without transmitting network packets.
The generated output is packaged into a local blob: URI and saved directly to your filesystem.
