The way the code is written, both parameters (dpi and size) are being sent to pdftoppm this means that the issue you are seeing is most likely not at the pdf2image level, but in the underlying library.

My best solution would be to resize the output of pdf2image manually instead of using the parameter. Something like:

from PIL import Image

images = convert_from_bytes(open('/content/sample_data/test.pdf', 'rb').read(), size=800,dpi=400)

images[0].thumbnail((800, 800)) # This is in place I think

display(images[0])
