Linux user here: I tried the convert command-line utility (for PDF to PNG) and I was not happy with the results. I found this to be easier, with a better result:

• extract the pdf page(s) with pdftk
  • e.g.: pdftk file.pdf cat 3 output page3.pdf
• open (import) that pdf with GIMP
  • important: change the import Resolution from 100 to 300 or 600 pixel/in
• in GIMP export as PNG (change file extension to .png)

Edit:

Added picture, as requested in the Comments. Convert command used:

convert -density 300 -trim struct2vec.pdf -quality 100 struct2vec.png

GIMP : imported at 300 dpi (px/in); exported as PNG compression level 3.

I have not used GIMP on the command line (re: my comment, below).
