From my point of view, that's not really tex to html. That's tex markup to html. I am talking about using the latex software, whose purpose is to do typesetting. The amazing thing about this converter is that it takes the latex OUTPUT and produces html.
What are some of the constraints on the PDF in terms of page dimensions or configuration?
How is the math translation done? Does it use MathML or something else?
For me, the interest is that I can now go LaTeX ---> Webpage.
