PDF2EPUB Converter

v1.0.1 · 🌐 English · 繁體中文 · 简体中文

A simple desktop GUI tool that converts PDF files to EPUB format. Output EPUBs ship without bundled styles, letting your reader (Kobo, etc.) apply its own typography.

Windows users: click the badge above to download the latest standalone .exe. You still need Calibre installed.

Features

• Converts text-based and scanned PDFs (OCR via Calibre)
• Drag-and-drop GUI built with CustomTkinter
• Preserves images and chapter structure from the source PDF
• No bundled CSS — reader controls typography
• Interface available in Traditional Chinese, Simplified Chinese, and English

Prerequisite

Install Calibre (free). The converter shells out to Calibre's ebook-convert.

Install & Run (from source)

pip install -r requirements.txt
python main.py

Build a Standalone .exe

pip install pyinstaller
pyinstaller --onefile --windowed --name "PDF2EPUB" --icon icon.ico --add-data "icon.ico;." --collect-all customtkinter --collect-all tkinterdnd2 main.py

Output: dist/PDF2EPUB.exe. Recipients still need Calibre installed.
