使用Python打造一款集成 PDF转换、编辑、加密、解密、图片提取、日志追踪 等多个功能于一体的桌面工具应用（Tkinter + ttkbootstrap + PyPDF2 等库）。
✨项目背景与开发动机
在日常办公或学习中，我们经常会遇到各种关于PDF文件的操作需求，比如：
-
将 PDF 转换成 Word 文档编辑
-
合并多个PDF为一个
-
分割PDF，按页导出
-
去掉PDF水印、加密、解密
-
从PDF中提取图片
-
将PDF每一页转为图片
-
旋转/删除指定页面
-
记录最近处理文件和操作日志
虽然市场上存在很多PDF软件，但免费+轻量+跨平台的桌面工具仍较少。于是我决定用 Python 打造一个集所有功能于一身的 PDF 工具箱，方便自己和他人使用！
🛠️主要技术栈与依赖
| 模块 | 功能 |
|---|---|
tkinter + ttkbootstrap | GUI 构建 |
tkinterDnD2 | 拖拽支持 |
PyPDF2, pdfplumber, fitz(PyMuPDF) | PDF编辑核心 |
pdf2image, PIL | PDF转图片 |
docx | Word文档生成 |
threading, json, os | 多线程处理和状态记录 |
📂功能结构总览
该程序结构如下图（部分简化）：
PDFToolboxApp
├── PDF 转 Word（支持去水印）
├── PDF 分割（每页单独导出）
├── PDF 合并
├── PDF 加密 / 解密
├── 提取 PDF 中的图片
├── 页面旋转
├── 删除指定页面
├── PDF 转图片
└── 查看日志记录
接下来我们分模块详细介绍每个功能实现。
🧾基础组件与通用功能
🔹 日志与历史文件记录
-
log_action(action, file)
每次用户进行操作（如打开、转换文件）都记录到日志文件pdf_toolbox_logs.txt中。 -
add_to_history(filepath)
最近打开文件记录在pdf_toolbox_history.json中，便于下次快速访问。 -
get_recent_history()
读取最近10个操作过的文件。
🔹 去水印功能
def remove_watermark(text):WATERMARK_KEYWORDS = ["Confidential", "Watermark", "Do Not Copy", "内部资料", "机密"]return '\n'.join(line for line in text.split('\n') if not any(wm in line for wm in WATERMARK_KEYWORDS))
📄PDF 转 Word（支持去水印）
pdfplumber.open(path) → page.extract_text() → remove_watermark() → Word文档-
使用
pdfplumber提取 PDF 每一页文本内容 -
可勾选“去水印”选项过滤掉机密/水印文本
-
保存为
.docx格式，支持拖拽上传PDF
✂️PDF 分割
每页导出为独立文件：
for i, page in enumerate(reader.pages): writer.add_page(page) writer.write(f"page_{i+1}.pdf")用户选择PDF并设置导出目录后，将每一页保存为独立PDF文件。
➕PDF 合并
多文件合并为一个：
for f in files: for p in PdfReader(f).pages: writer.add_page(p)支持多选文件，按照选择顺序合并。
🔐PDF 加密 / 解密
-
加密： 输入密码 → 写入新PDF
-
解密： 输入正确密码 → 导出解密版本
writer.encrypt(password) reader.decrypt(password)🖼️提取PDF图片
使用 fitz（PyMuPDF）逐页扫描PDF，提取嵌入图片并保存为 PNG：
for page_index in range(len(doc)): for img in doc[page_index].get_images(full=True): pix = fitz.Pixmap(doc, img[0]) pix.save(...)🔄页面旋转
用户输入：
-
页码：
1,2,3 -
角度：
90
代码示例：
if i + 1 in pages: page.rotate(angle)🗑️删除指定页面
输入页码列表，如 2,5,7，将这些页从PDF中删除并保存新版本。
🖼️PDF 转图片（每页转 PNG）
images = convert_from_path(file)
for i, img in enumerate(images): img.save(f"page_{i+1}.png")适合需要提取PDF为PPT使用或网页插图等。
🧾日志查看
简单读取 pdf_toolbox_logs.txt 文件，展示操作记录，便于溯源。
with open(LOG_FILE) as f: self.log_text.insert(tk.END, f.read())🧵多线程支持
通过 @threaded 装饰器包装耗时操作（如转换）避免 GUI 卡死：
def threaded(fn): def wrapper(*args, **kwargs): threading.Thread(target=fn, args=args, kwargs=kwargs).start()🎬运行入口
if __name__ == '__main__': app = TkinterDnD.Tk() PDFToolboxApp(app) app.mainloop()使用 TkinterDnD2 支持拖拽，整体体验更为现代化。
✅总结亮点
-
支持所有常用 PDF 操作（转换、编辑、处理、日志）
-
界面清晰、操作直观、支持拖拽上传
-
轻量级、不依赖大型软件，可本地私有化使用
-
拥有日志与历史记录，适合办公自动化场景
