参考： pdf2image

pip install pdf2image

代码：

from pdf2image import convert_from_path, convert_from_bytes
import osoutput_folder = './xx/'
dpi_value= 600
pdf_start_page = 1 # pdf显示的第一页
start_page = 1 # 真实页码
prex = '' # 图像前缀def to_image():def page_generator():# 定义图像前缀while True:yield preximages = convert_from_path(r'xx.pdf', dpi=600, output_folder=output_folder,first_page=pdf_start_page, fmt='jpg', thread_count=6, output_file=page_generator())def image_rename():# 文件重命名global start_pagefile_list = os.listdir(output_folder)for file in file_list:start_page_str =  str(start_page)if len(start_page_str)==1:start_page_str = '00'+start_page_strelif len(start_page_str)==2:start_page_str = '0'+start_page_strelse:...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() #文件重命名

效果：非常快
