convertToElements(): returns a list of iText IElement instances.

convertToDocument(): returns Document instance.

HtmlConverter class has three main methods with different inputs and return types:.

HtmlConverter class is the main class to convert HTML to PDF.

We need to add iText core library and pdfHTML add-on to our project dependencies.

“When using iText PDF in a closed source environment, you will need to purchase an iText PDF commercial license.” Environment, Tools & Libraries used in this post This post shows how to use iText to convert HTML to PDF. iText has an add-on that enables converting HTML to PDF document.
