[PDF] Export all pages as PNG in one go?

Hello

Someone sent me a presentation where slides are part of a PDF file instead
of the more common PowerPoint.

When opening the file in LibreOffice Draw, I can select each page and hit
File > Export to get a PNG file, but it appears that it's not possible to
select all the pages with CTRL, hit Export, and get the pages as independant
files as eg. Page1.png, Page2.png, etc.

Acrobat Professional can do this:

Is there a work-around in Draw?

Thank you.

​I believe that LibreOffice is not the appropriate tool to do this, as it
is not a PDF editor.

There is other tools far more efficient for this, that can render an almost
pixel-perfect output of your PDF files, like imagemagick. It is also
available for windows: http://www.imagemagick.org/script/binary-releases.php

Once installed, you can use a single-line command to do the conversion:
"convert -density 300 input.pdf output.png" will convert the PDF to a
series of PNG files, as if the PDF was rendered at 300 dpi. Usually, using
96 dpi gives acceptable results for display, but it depend on your goal.

Thanks for the infos.

ImageMagick did the trick, so I didn't try the LO extension.

convert -density 96 input.pdf +adjoin -alpha remove -alpha off output.png
