I was getting crazy to convert pdf into images and html until i found this free tool. I know there are millions of applications out there to do this and that the problem you can get crazy triyng to find one that actualy works.
The only problem is that it is a bit tricky to understand how to make it work but once you do you will love it.
1- Download and install xpdf
http://www.foolabs.com/xpdf/download.html
ftp://ftp.foolabs.com/pub/xpdf/xpdfbin-win-3.04.zip
2- Open a console and navigate to the the folder you have the different xpdf applications
(you can add the applications to your system path if you want)
in my case:
C:open-ecommerce0_toolspdf-convertionsbin64pdf
3- Run the command lines from the console
4- You will see all options for each application in the doc folder
Command line samples:
To get info about the file like pages, author etc
pdfinfo filename.pdf
To convert pdf to html
pdftohtml -f 1 filename.pdf myhtmlfolder
-the option -f 1 it mandate to start from the first page
-the myhtmlfolder where the exports goes
to convert pdf to png
pdftopng -f 1 filename.pdf prefixfilename
-the option -f 1 it mandate to start from the first page
-the prefixfilename how the png exported filenames will start.
