Python全功能PDF工具箱GUI：支持转换、加密、旋转、图片提取、日志记录等多功能操作

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

---

📦部署建议

安装依赖：

pip install tkinterdnd2 ttkbootstrap PyPDF2 pdfplumber python-docx pymupdf pdf2image pillow

如果你要将其打包为桌面可执行程序：

pyinstaller -F -w pdf_toolbox.py
