Hi, I can see your code, but I can not run it, because there is a problem for me to install poppler. My operation system is win10, and the version of python is 3.7.3. So, do you know some commands to install poppler? Thanks a lot!

In the convert.py script the format of the image conversion is set to TIFF, so each pdf slide is converted to a TIFF image. This works fine and creates a pptx file of reasonable size. However, if you open the pptx file in powerpoint, make a trivial change and save it, the file size may increase by a factor of 50 (!), evidently because the TIFF image is not compressed.

If you change the image format to PNG it all works fine and the pptx file can be edited if needs be without an enormous increase in file size. Just change:
slideimg.save(imagefile, format='tiff')
to
slideimg.save(imagefile, format='png')
and it all seems to work, although I have not extensively checked and there may be other issues.

Otherwise, works like a charm. Thanks for the script.

How can I set the output resolution in pixels? The current code has this:

	# Set slide dimensions
	prs.slide_height = height * 9525
	prs.slide_width = width * 9525

	# Add slide
	slide = prs.slides.add_slide(blank_slide_layout)
	pic = slide.shapes.add_picture(imagefile, 0, 0, width=width * 9525, height=height * 9525)

There is multiplier of 9525 but I want to fix the output to 1920x1080px. What units does the number relate to and can a pixel value be set?
