主程序代码：

from PyQt5 import QtWidgets
from pdf2jpg import Ui_Dialog_main # 导入ui文件转换后的py文件
from PyQt5.QtWidgets import QFileDialog
import pandas as pd
import fitz
from operator import itemgetter
import os,sys
import time
#from saveFile import a_save_txt

class mywindow(QtWidgets.QWidget, Ui_Dialog_main):
    def  __init__ (self):
        super(mywindow, self).__init__()
        self.setupUi(self)

        print(filename, filetype)
        self.lineEdit_file.setText(filename)

    def write_folder(self):
        #选取文件夹
        foldername = QFileDialog.getExistingDirectory(self, "选取文件夹", "C:/")
        print(foldername)
        self.lineEdit_fold.setText(foldername)



    # 进行处理
    def process(self):
        try:
            #获取文件路径
            file_path = self.lineEdit_file.text()

            sTime = time.time()
            pdfDoc = fitz.open(file_path)
            for pg in range(pdfDoc.pageCount):
                page = pdfDoc[pg]
                pix = page.getPixmap(alpha=False)  # 默认是720*x尺寸
                if not os.path.exists(folder_path):

                pix.writePNG(folder_path + '/' + 'images_%s.jpg' % pg)  # 将图片写入指定的文件夹内
            #读取文本
                #
            # 读取文件
            #my_df = pd.read_csv(file_path, encoding = 'mbcs')

            # 中间可以进行对文件的任意操作

            # 进行csv输出
            #my_df.to_csv(folder_path + '\result.csv')


            eTime = time.time()
            s = eTime - sTime
            print('花费的时间为：%.2f秒' % (s))
            success_result = r'转换成功！'
            self.setWindowTitle(success_result)
            #打开成功后的文件夹

            os.startfile(folder_path)

        except:
            fail_result = r'转换失败！'
            self.setWindowTitle(fail_result)

if __name__=="__main__":
    import sys
    app=QtWidgets.QApplication(sys.argv)
    ui = mywindow()
    ui.show()
    sys.exit(app.exec_())

经测试可以通过

生成可执行文件。

>pyinstaller -F -w pdf2jpg_server.py

此可执行文件有需要的可留言。

完成后自动打开所在文件夹。收工。下一步接着完善。
