PDFCreator can print to many different file formats other than just PDF.
You could print to BMP, PNG, JPEG and many others. When you print the file,
select PDFCreator as a printer, then select Options on the next dialog,
adjust your options for the image format you're saving to, then in the next
dialog select the file format you'd like to save to, it's really simple.

The added benefit is that you can use this to print from any application to
save to image formats as well as PDF.

thanks for your words. I have done a little experiment

from same pdf file, I have printed with your method (pdf creator) and
converted a single page to:

- monochrome png image file (2 bit) 300 DPI resolution (ideal settings to
only text pages)

A friend with his ADOBE ACROBAT full version, has saved as image the same
page, with identical export settings (monochrome png image file (2 bit)
300 DPI resolution)

Now. comparating results, his png looks better than mine. Why This?

Also try GsView and Ghost Script:

Note, I think in GSView you have to save each page as a png and jpg as
a separate operation even though the program appears to give you the
option ove of saving several pages at one tiime (i.e. producing one
image for each PDF page in a batch). So save the PDF file as a jpg for
page one, then move the selection to page 2 and save page 2 as a jpg or
png etc...

At least that's the way the program worked for me, although it was an
older version than the one currently offered I'm sure.

Sorry for the late reply.
The difference is largely on how the export filter works. You see, PDF's
are saved as compressed PostScript files. If you export to PostScript, you
will probably not see a difference. If you export to anything else,
internally there's a rendering engine, for PDFCreator its GhostScript, and
it has it's own interpretation of what things should look like. Adobe use
their own. For the best exports, I always export to PostScript (if I use
Acrobat or PDFCreator) and then use a graphics package to convert it. The
down side is that you can only do one page at a time this way. Another
consideration is that Acrobat might very well directly extract the PS
directly and convert it, whereas PDFCreator and all of the GhostScript
printers first print the document to PostScript and then convert it, so the
process goes through a print process before it's converted, adding a step
and possibly compromising final quality.

If you were to use GSView as indicated elsewhere in this thread, you'll
notice that the final representation of a PDF on the screen is not as nice,
quality wise, as it is if you view the file in Acrobat. Again, this has
everything to do with how the internal PS structure is interpreted by
GhostScript. BTW, it looks as though GSView can directly export the
PostScript information so you might be better off just extracting the PS
and converting it with your favorite graphics package.
