In my ASP.NET MVC application, user can upload a PDF file. I want to write a string to a specific location of that file and let the user download the modified PDF. How can I do that? Is there a (hopefully free) library for this kind of task? Thanks in advance.

  • This question effectively asks for a library recommendation which is off topic on stack overflow. – mkl Apr 12 '17 at 14:30
