GhostScript performs much faster than Poppler for a Linux based system.

Following is the code for pdf to image conversion.

def get_image_page(pdf_file, out_file, page_num):
    page = str(page_num + 1)
    command = ["gs", "-q", "-dNOPAUSE", "-dBATCH", "-sDEVICE=png16m", "-r" + str(RESOLUTION), "-dPDFFitPage",
               "-sOutputFile=" + out_file, "-dFirstPage=" + page, "-dLastPage=" + page,
               pdf_file]
    f_null = open(os.devnull, 'w')
    subprocess.call(command, stdout=f_null, stderr=subprocess.STDOUT)

GhostScript can be installed on macOS using brew install ghostscript

Installation information for other platforms can be found here. If it is not already installed on your system.

The Python library pdf2image  used in the other answer  in fact doesn t do much more than just launching pdttoppm with subprocess Popen  so here is a short version doing it directly   PDFTOPPMPATH   r D  Documents software     PORTABLE poppler-0 51 bin pdftoppm exe  PDFFILE    SKM 28718052212190 pdf   import subprocess subprocess Popen    s  -png   s  out     PDFTOPPMPATH  PDFFILE     Here is the Windows installation link for pdftoppm  contained in a package named poppler   http   blog alivate com au poppler-windows

There is no need to install Poppler on your OS  This will work   pip install Wand  from wand image import Image  f    somefile pdf  with Image filename f  resolution 120   as source       for i  image in enumerate source sequence           newfilename   f  -4    str i   1      jpeg          Image image  save filename newfilename

I use a  maybe  much simpler option of pdf2image   cd  dir for f in   pdf do   if   -f    f      then     n   echo   f    cut -f1 -d         pdftoppm -scale-to 1440 -png  f  conv  n     rm  f     mv   conv   png  dir   fi done   This is a small part of a bash script in a loop for the use of a narrow casting device  Checks every 5 seconds on added pdf files  all  and processes them  This is for a demo device  at the end converting will be done at a remote server  Converting to  PNG now  but  JPG is possible too   This converting  together with transitions on A4 format  displaying a video  two smooth scrolling texts and a logo  with transition in three versions  sets the Pi3 to allmost 4x 100  cpu-load  -
