To merge multiple PDF files into a single unified document, select your source PDF files, arrange their desired reading sequence, and compile them using a modern client-side PDF merger. Modern browser tools utilize WebAssembly and JavaScript libraries (such as `pdf-lib`) to parse the underlying ISO 32000 document object trees, reconcile cross-reference tables (XREFs), and deduplicate shared fonts entirely inside browser memory without uploading sensitive legal or financial paperwork to remote servers.
