Question [PDF] Text to image: pdftocairo or pdftoppm?

Hello,

Calling the Poppler experts

As an easier way than trying to turn it into EPUB, a work-around to read a PDF on an e-reader is to simply turn each page that contains complicated layout into an image. I know it's not as nice as real text, it won't be flowable, but it could be good enough to read.

I see that Poppler offers two applications for this purpose: pdftocairo and pdftoppm.

I have a few questions:
  1. Which application do you recommend?
  2. Should pages be saved as JPG, PNG, or SVG?
  3. What settings should I use for an e-reader whose screen is 768x1024 pixels?
  4. How to crop pages and get rid of the circles on the sides (used by printers for adjustement?)?

Thank you.
