It stands out for its versatility in handling multiple document formats beyond just PDFs, including XPS, EPUB, and various image formats. PyMuPDF provides comprehensive document manipulation capabilities, including advanced text extraction with precise positioning information, image extraction and insertion, and annotation handling. The library's architecture is designed to provide both high-level convenience functions and low-level access to PDF structures when needed.

Pros

• Supports multiple file formats (PDF, XPS, EPUB)
• Strong text and image extraction
• Excellent performance
• Comprehensive feature set
• Good documentation

Cons

• Requires C dependencies
• A commercial license needed for some uses
