Hi Jason,
Thank you for your interest in Essential PDF.
The conversion of HTML page to an PDF document is done as follows:
1. The HTML page is first converted to an bitmap image or a Metafile.
2. Then the image is drawn into the PDF document.
As the HTML page is converted to an image, the text may not be searchable inside the PDF.
Here is a sample for your reference:

Thanks,
Bhagya.
