Adding Cover Pages to PDFs: A Pure Browser-Side Implementation

Introduction Have you ever needed to add a professional cover page to a PDF document? Whether it's for a business proposal, an e-book, or academic work, a well-designed cover can make all the difference. In this article, we'll explore how to implement a pure browser-side PDF cover addition tool that runs entirely in the client's browser without any server-side processing.

By processing files locally in the browser, we ensure that documents never leave the user's device, eliminating privacy concerns and data breach risks. Speed & Performance : No network upload/download means instant processing. Users don't have to wait for files to travel to a server and back, especially important for large PDFs. Offline Capability : The tool works without an internet connection once
