The Softnag PDF Merger utilizes the WebAssembly-compiled pdf-lib engine running directly in your browser.
When you select multiple PDF files, the browser reads their binary streams as Uint8Array byte buffers. The engine parses the PDF object cross-reference tables (XREF) and copies the page dictionary trees, content streams, and font resources into a new target document.
Because the binary manipulation executes in local memory without server round-trips, merging occurs in seconds with 100% confidentiality guaranteed.
