Sample Application 1
Convert all pdf file in a given path to images

# Seach for path the contains pdfinfo and set it as poppler_path, 
# in my case it was : /usr/local/bin/pdfinfo



from pdf2image import convert_from_path

def ConvertPdfFile2Image(PDFfileName):
    dpi=500
    output_folder=None
    first_page=None
    last_page=None
    fmt='ppm'
    thread_count=1
    userpw=None
    use_cropbox=False
    strict=False
    transparent=False
    single_file=False
    output_file=''
    poppler_path='/usr/local/bin/'

    pages = convert_from_path(PDFfileName, dpi, output_folder, first_page, last_page, fmt, thread_count, userpw, use_cropbox, strict, transparent, single_file, output_file, poppler_path)
    for i in range(len(pages)):
        newfilename = PDFfileName[:-4] + str(i) + '.jpeg'
        pages[i].save(newfilename, 'JPEG')



import os
pdf_dir = r"/Users/rafie/Desktop/"
os.chdir(pdf_dir)

for pdf_file in os.listdir(pdf_dir):
    if pdf_file.endswith(".pdf"):
        ConvertPdfFile2Image(pdf_file)
     

Sample Application 2

from pdf2image import convert_from_path
import requests
def ConvertOnlinePdf2Images(pdfFileURL,outputPath):
    dpi=500
    output_folder=None
    first_page=None
    last_page=None
    fmt='ppm'
    thread_count=1
    userpw=None
    use_cropbox=False
    strict=False
    transparent=False
    single_file=False
    output_file=''
    poppler_path='/usr/local/bin/'

    pdfFileBytes = requests.get(pdfFileURL)

    pages = convert_from_bytes( pdfFileBytes.content, dpi, output_folder, first_page, last_page, fmt, thread_count, userpw, use_cropbox, strict, transparent, single_file, output_file, poppler_path)
    for i in range(len(pages)):
        newfilename = outputPath + str(i) + '.jpeg'
        pages[i].save(newfilename, 'JPEG')
