In Ghost4J library  http   ghost4j sourceforge net   since version 0 4 0 you can use a SimpleRenderer to do the job with few lines of code    Load PDF or PS file  use PSDocument class for that        PDFDocument document   new PDFDocument        document load new File  input pdf      Create the renderer      SimpleRenderer renderer   new SimpleRenderer            set resolution  in DPI      renderer setResolution 300    Render      List lt Image gt  images   renderer render document      Then you can do what you want with your image objects  for example  you can write them as PNG like this               for  int i   0  i  lt  images size    i                      ImageIO write  RenderedImage  images get i    png   new File  i   1      png                     Note  Ghost4J uses the native Ghostscript C API so you need to have a Ghostscript installed on your box   I hope it will help you

Apache PDF Box can convert PDFs to jpg bmp wbmp png  and gif    The library even comes with a command line utility called PDFToImage to do this    If you download the source code and look at the PDFToImage class you should be able to figure out how to use PDF Box to convert PDFs to images from your own Java code

You will need a PDF renderer  There are a few more or less good ones on the market  ICEPdf  pdfrenderer   but without  you will have to rely on external tools  The free PDF renderers also cannot render embedded fonts  and so will only be good for creating thumbnails  what you eventually want    My favorite external tool is Ghostscript  which can convert PDFs to images with a single command line invocation   This converts Postscript  and PDF   files to bmp for us  just as a guide to modify for your needs  Know you need the env vars for gs to work     pushd  setlocal  Set BIN DIR C  Program Files IKOffice ACME bin Set GS C  Program Files IKOffice ACME gs Set GS DLL  GS  gs8 54 bin gsdll32 dll Set GS LIB  GS  gs8 54 lib  GS  gs8 54 Resource  GS  fonts Set Path  Path   GS  gs8 54 bin Set Path  Path   GS  gs8 54 lib  call   GS  gs8 54 bin gswin32c exe  -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE bmpmono -r600x600 -sOutputFile  2 -f  1  endlocal popd   UPDATE  pdfbox is now able to embed fonts  so no need for Ghostscript anymore
