If the PDF is online then you can have it converted and sent via email
back to you using these email addresses:
pdf2html@adobe.com Convert an Adobe PDF to HTML.

If the PDF is on your PC, then Ghostscript is best for viewing.
Welcome to the Home Page for Ghostscript, an interpreter for the
PostScript language and for PDF, and related software and documentation.
