EVO HTML to PDF Converter allows you to transform any HTML element to an URI link in PDF by setting the data-link-enabled and data-link_href attributes on HTML element. With data-link-enabled attribute you can also disable the automatic conversion of a HTML URI link to a PDF link when you set this attribute to false.
