代码展示

先安装依赖

pip install PyMuPDF

输入文件列表

import os
import fitz


def single_wordpdf_to_imgpdf(pdf_path: str):
    pdf = fitz.open(pdf_path)   # 打开pdf目录
    pdf_img = fitz.open()       # 打开空文件，用来存图片pdf
    for page_inf in pdf:
        definition = 3    # 清晰度，感觉输出的pdf不够清晰，可以调大，调大，文件大小也会变大
        matrix = fitz.Matrix(definition, definition)
        img = page_inf.get_pixmap(matrix=matrix).tobytes()
        img = fitz.open("png", img)
        pdf_bytes = img.convert_to_pdf()
        pdf_img.insert_pdf(fitz.open("pdf", pdf_bytes))
    pdf_img.save("图片pdf_" + os.path.basename(pdf_path))


def group_wordpdf_to_imgpdf(path_array: list[str]):
    for pdf_path in path_array:
        print(pdf_path, "转换中...")
        single_wordpdf_to_imgpdf(pdf_path)
    print("完成")


if __name__ == '__main__':
    path = ["xxx.pdf"]
    group_wordpdf_to_imgpdf(path)

输入文件夹

                    file_list.append(file_path)
    print(folder, ": 有", len(file_list), "个pdf文件")
    return file_list

    print("程序运行时间：", round(time_end - time_start, 2), "秒")
