Their is a utility called pdftojpg which can be used to convert the pdf to img

You can found the code here https://github.com/pankajr141/pdf2jpg

from pdf2jpg import pdf2jpg
inputpath = r"D:\inputdir\pdf1.pdf"
outputpath = r"D:\outputdir"
# To convert single page
result = pdf2jpg.convert_pdf2jpg(inputpath, outputpath, pages="1")
print(result)

# To convert multiple pages
result = pdf2jpg.convert_pdf2jpg(inputpath, outputpath, pages="1,0,3")
print(result)

# to convert all pages
result = pdf2jpg.convert_pdf2jpg(inputpath, outputpath, pages="ALL")

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

The pdf2image library can be used   You can install it simply using    pip install pdf2image   Once installed you can use following code to get images   from pdf2image import convert from path pages   convert from path  pdf file   500    Saving pages in jpeg format  for page in pages      page save  out jpg    JPEG       Edit  the Github repo pdf2image also mentions that it uses pdftoppm and that it requires other installations      pdftoppm is the piece of software that does the actual magic  It is distributed as part of a greater package called poppler    Windows users will have to install poppler for Windows    Mac users will have to install poppler for Mac    Linux users will have pdftoppm pre-installed with the distro  Tested on Ubuntu and Archlinux  if it s not  run sudo apt install poppler-utils    You can install the latest version under Windows using anaconda by doing   conda install -c conda-forge poppler   note  Windows versions upto 0 67 are available at http   blog alivate com au poppler-windows  but note that 0 68 was released in Aug 2018 so you ll not be getting the latest features or bug fixes

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  -

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
