I've researched quite a few tools that aren't 8 offered specifically by Adobe, and the two 7 that come to mind right away are Atalasoft's DotImage and LEADTools. They 6 are both rather pricy, but provide server 5 licensing and use the ultra-fast C++ GDI 4 libraries.

There's a freeware .Net library 3 called PDFSharp that uses .Net native GDI+, so it's 2 slower and memory intensive. But then again, it's 1 free.

webSupergoo have a super PDF library for 12 .NET

Their ABCpdf product is designed for 11 use with web servers. The documentation 10 is clear and the installation is accompanied 9 by an example website project.

If you visit 8 their website you should see a link to the 7 live demonstration:


ABCpdf 7 is the current 6 version. The performance and reliability 5 is excellent. The standard version costs 4 $329 USD, but sometimes an installation 3 can be obtained for free. The download size 2 is about 30 MB. Supports both 32 and 64-bit 1 servers.

I've used http://www.tallcomponents.com/ mainly to fill in pdf forms and 2 then flatten the pdf. Seems to work fine. I 1 haven't had any issues.

I don't know if it's the best, but I use 8 PDF-Writer.NET, for which I paid $89. I have used it in 7 several production applications. I like 6 it because it's easy to set up and use, and 5 it doesn't require a lot of coding, which 4 makes it easier for new developers to ramp 3 up on it.

Before that I was hacking together 2 PDFs using an open source library and the 1 Acrobat interop DLLs. That was rough.
