A free PDF library is rarely one library

Building a real PDF feature on free packages usually means assembling a stack: one library to render your HTML, another to edit or merge the result, a third to handle signatures or encryption. Each brings its own API to learn, its own licence to check, and its own maintenance risk — and they were never designed to work together. Some ask you to rebuild layout in C# by hand; some ship under copyleft licences that reach into your own source; some stopped being maintained years ago. IronPDF is one supported library that generates, edits, merges, signs, and secures behind a single clean .NET API, with a commercial licence and an engineer on the other end of the ticket.
