How Does NoPayWall Merge PDF Files Without Server Uploads?

NoPayWall merges PDF documents entirely inside your browser using client-side WebAssembly, ensuring zero bytes of document data ever leave your computer. While conventional cloud utilities transmit confidential files over HTTP to multi-tenant servers, NoPayWall compiles the open-source PDF-Lib engine into local web worker threads. Your computer reads the local file binary arrays, reconstructs the document page trees in RAM, and exports the merged document directly to your downloads directory.
