安装poppler https://wenku.csdn.net/answer/1zxh8ckp6i

from pdf2image import convert_from_path, convert_from_bytes
import os


# https://github.com/Belval/pdf2image

output_folder = './'
dpi_value= 600
pdf_start_page = 1 # pdf显示的第一页
start_page = 237 # 真实页码
prex = '' # 图像前缀

def to_image():
    def page_generator():
        while True:
            yield prex
    images = convert_from_path(r'xxx.pdf', dpi=600 ,output_folder=output_folder,
    first_page=pdf_start_page,fmt='jpg',thread_count=6 , output_file=page_generator())
    # convert_from_path(pdf_path, dpi=200, output_folder=None, first_page=None, last_page=None, fmt='ppm', jpegopt=None, thread_count=1, userpw=None, use_cropbox=False, strict=False, transparent=False, single_file=False, output_file=str(uuid.uuid4()), poppler_path=None, grayscale=False, size=None, paths_only=False, use_pdftocairo=False, timeout=600, hide_attributes=False)


# 结果 prex-237.jpg
def image_rename():
    # 文件重命名
    global start_page
    file_list = os.listdir(output_folder)
    for file in file_list:
        start_page_str = prex + str(start_page)
        path = os.path.join(output_folder, file)
        print(os.path.join(output_folder, start_page_str + '.jpg'))
        os.rename(path, os.path.join(output_folder, start_page_str + '.jpg'))
        start_page = start_page + 1
to_image()
image_rename()
