How Privacy First Processing Works
Zero-Knowledge Architecture
When you select a file, it's read by the browser's File API into local memory. Processing happens via WebAssembly (compiled C/C++/Rust running in the browser sandbox) and Web Workers. The result is generated locally and offered as a download. At no point does any file data leave your device.
