批量JPG转PDF自动化处理方案

多JPG转同名PDF并自动生成单一文件夹的技术实现在日常办公场景中职称评审等流程常涉及将大量荣誉证书JPG格式转换为同名PDF文件并归档的需求。以下方案通过Python脚本实现批量转换与自动化管理兼顾效率与文件结构清晰性。环境准备与依赖安装确保系统已安装Python 3.6环境。核心依赖库为Pillow图像处理和PyPDF2PDF操作通过以下命令安装pip install Pillow PyPDF2验证安装是否成功from PIL import Image import PyPDF2 print(依赖库加载成功)文件结构设计假设原始JPG文件存放于/input_images目录每个文件命名格式为姓名_证书类型.jpg如张三_优秀员工.jpg。目标输出结构为/output/ ├── 张三/ │ ├── 张三_优秀员工.pdf │ └── 张三_技术能手.pdf └── 李四/ ├── 李四_专利证书.pdf └── 李四_论文发表.pdfJPG转PDF核心代码定义单文件转换函数保留原始分辨率并优化PDF体积from PIL import Image def jpg_to_pdf(input_path, output_path): image Image.open(input_path) if image.mode RGBA: image image.convert(RGB) image.save(output_path, PDF, resolution300, save_allTrue)参数说明resolution300设置DPI为300适合打印质量save_allTrue兼容多帧图像如动态GIF批量处理与文件夹管理实现自动化分类与批量转换import os from pathlib import Path def batch_convert(input_dirinput_images, output_diroutput): Path(output_dir).mkdir(exist_okTrue) for jpg_file in Path(input_dir).glob(*.jpg): # 提取姓名作为子文件夹名 name jpg_file.stem.split(_)[0] person_dir Path(output_dir) / name person_dir.mkdir(exist_okTrue) # 生成PDF路径并转换 pdf_path person_dir / f{jpg_file.stem}.pdf jpg_to_pdf(str(jpg_file), str(pdf_path)) print(f转换完成: {jpg_file} - {pdf_path})异常处理增强版try: batch_convert() except Exception as e: print(f处理失败: {str(e)}) # 可追加日志记录功能进阶优化方案1. 元数据注入为PDF添加作者、标题等元信息from PyPDF2 import PdfFileWriter, PdfFileReader def add_metadata(pdf_path, author, title): with open(pdf_path, rb) as f: pdf PdfFileReader(f) writer PdfFileWriter() for page in range(pdf.getNumPages()): writer.addPage(pdf.getPage(page)) writer.addMetadata({ /Author: author, /Title: title }) with open(pdf_path, wb) as out: writer.write(out)2. 多线程加速适用于大规模文件处理from concurrent.futures import ThreadPoolExecutor with ThreadPoolExecutor(max_workers4) as executor: futures [executor.submit(jpg_to_pdf, str(f), str(out)) for f in Path(input_dir).glob(*.jpg)]完整脚本示例整合
