How does it stay private?

ViewAnyFile.app uses WebAssembly (WASM) — the same secure, sandboxed technology that powers browser-based games and design tools. When you open a file, the parsing library runs directly inside your browser tab. There is no network request, no server, no cloud storage. The file path never leaves your computer.

Every other major online viewer (Smallpdf, iLovePDF, Zamzar, CloudConvert, GroupDocs, Aspose) uploads your file to their servers. ViewAnyFile.app is structurally different — the processing code comes to your file, not the other way around.
