HTML to PDF Converter Library 8.0 for .NET
The Winnovative HTML to PDF Converter library for .NET can be linked into any .NET application, either ASP.NET web sites or Windows Forms and WPF applications, to convert URLs, HTML strings and streams to a PDF document or to an image.

You can use the HTML to PDF Converter for .NET as a general purpose tool for converting web pages and HTML code to PDF and images or you can use it as part of our .NET Reporting Toolkit to easily create PDF reports directly from ASP.NET pages and to benefit from the great power of ASP.NET controls.

The converter offers full support for HTML tags and CSS, page breaks control with CSS styles, automatically repeating HTML table header on each PDF page, live URLs and internal links in PDF, automatically generated bookmarks, HTML in the headers and footers.

The HTML to PDF Converter is not using a printer driver and no special settings are necessary on the server in order to get it working. The same assembly works both in 32-bit and 64-bit environments and xcopy deployment on the server is supported. The library is compatible with .NET 2.0, .NET 3.5 and .NET 4.0 frameworks and with Windows Azure Cloud applications.

The library was designed and tested to work reliably in multithreaded environments and to completely release all the resources used during conversion after each conversion. This makes it suitable for usage in high traffic ASP.NET websites and services running a long period of time without interruption.
