PDF Toolbox is engineered with a strict browser-first architecture. All file operations execute entirely in your local browser sandbox via modern WebAssembly and JavaScript engines. No file bytes or sensitive document data are ever uploaded, buffered, or stored on external servers or cloud infrastructure. Memory buffers are cleared immediately when you finish or close your tab.
