Converting an HTML page to PDF

In This Topic

Prerequesties

A Google Chrome or Edge browser is required to support HTML content as input into the whole toolkit scope.

If Chrome or Edge is already installed on your machine, no action on your part is necessary.

If it’s not the case, you have two options to make it work with Chrome:

- 1. Install Google Chrome Portable in the installation folder. You can download Google Chrome Portable here.

- 2. Set the path of the chrome.exe portable version with the SetWebBrowserPath() method.

Converting an HTML page, from an URI, to a PDF document.

The ClearWebBrowserCache method must be called before the application exits to clear temporary data if browser pooling is enabled.
