WebKit OPX


Syncfusion’s PDF Library now supports HTML-to-PDF conversion using the advanced WebKit rendering engine. This converter can easily be integrated into any application of a .NET platform, such as WF, WPF, MVC, and Azure Cloud Service, to convert URLs, HTML strings, SVG, and MHTML to PDF.

Building the sample

The sample showcased here covers most of the important features of HTML-to-PDF conversion. To deploy the sample, you need to install the WebKit HTML converter, which is available in the link below.

WebKit HTML converter: https://www.syncfusion.com/downloads/latest-version

GitHub location of WebKit: https://github.com/syncfusion/SfQtWebKit

After the installation, the WebKitPath property of an instance of the WebKitConverterSettings class should be assigned to the QtBinaries directory in the installed location. By default, this will be the installed location.

$SystemDrive\Program Files (x86)\Syncfusion\WebKitHTMLConverter\xx.x.x.xx\QtBinaries

Alternatively, you can place the QtBinaries folder in the application bin folder, which needs no reference in the code behind.


The PDF Library easily converts HTML to PDF. The converter is very reliable and provides full support for HTML tags, CSS, and JavaScript, and also for advanced HTML5 features like CSS3, Canvas, SVG, and web fonts.

Our PDF WebKit rendering is accurate and the result preserves all the graphics, images, texts, fonts, and layout of the original HTML document/webpage.

It does not require external dependencies like browsers, printer drivers, and viewers.
