Free PDF libraries are cheap to install and expensive to keep

The free options each ask for something back. A fluent drawing API asks you to rebuild layout in C# and re-code it every time marketing moves a logo. A browser automation wrapper asks you to ship, patch, and memory-manage a Chromium binary in production. A copyleft licence asks you to open-source your application or negotiate a commercial deal anyway. An abandoned WebKit port asks you to explain to your team why flexbox does not render. IronPDF is a supported Chromium engine behind a clean .NET API, with a commercial licence and an engineer on the other end of the ticket.
