Automation plugin for EPUB processing with interactive menu, batch processing and recursive scanning.

Use this with caution. It would not break your epub, but it can.

EPUB Workflow is a Calibre plugin that automates EPUB file processing with an intuitive graphical interface. It offers several processing actions that you can combine according to your needs:

• Convert EPUB to EPUB : Refresh HTML
• Repair HTML : Fix HTML errors
• Beautify : Format and indent code
• Remove unused CSS : Remove unused CSS
• Check and auto-fix errors : Check and automatically fix errors
• Remove embedded fonts : Remove embedded fonts
• Resize images to 480px : Resize images for Xteink e-readers (irreversible)

• 🎯 Intuitive graphical interface : Easily select actions to perform
• 📦 Batch processing : Process multiple EPUBs at once
• 🔄 Automatic backup : A backup copy is automatically created before any modification
• 🌍 Multilingual : French and English support (follows Calibre's language)
• ⚡ Fast processing : Uses Calibre's polish tools for efficient processing

1. Download the epub_workflow_plugin.zip file
2. Open Calibre

• French : If Calibre is in French
• English : Default or if Calibre is in another language

• .kepub.epub files are automatically ignored
• The plugin requires Calibre 6.0 or higher
• The backup copy is overwritten if it already exists during a new processing

A standalone Python script version is available in the Python-CLI folder for command-line use without Calibre.

• The plugin can only process EPUB files. If you select books in other formats, a message will invite you to convert them to EPUB first.
