Best Server-side .NET PDF editing library [closed]


Have a look at iTextSharp. iTextSharp is a port of the iText , a free Java-Pdf library.

To quote iText:

You can use iText to:

  • Serve PDF to a browser
  • Generate dynamic documents from XML files or databases
  • Use PDF's many interactive features
  • Add bookmarks, page numbers, watermarks, etc.
  • Split, concatenate, and manipulate PDF pages
  • Automate filling out of PDF forms
  • Add digital signatures to a PDF file
  • And much more...


Syncfusion Essential PDF is the best. I have been using it for years. Also, Syncfusion provides a best support compared to other vendors.


I've researched quite a few tools that aren't offered specifically by Adobe, and the two that come to mind right away are Atalasoft's DotImage and LEADTools. They are both rather pricy, but provide server licensing and use the ultra-fast C++ GDI libraries.

There's a freeware .Net library called PDFSharp that uses .Net native GDI+, so it's slower and memory intensive. But then again, it's free.
