• Progress tracking with error recovery

Troubleshooting

Common Issues

1. “PyPDF2/pypdf not available”

   pip install PyPDF2
   # or
   pip install pypdf
   

2. “PIL/Pillow not installed”

   pip install Pillow
   

3. “PyMuPDF not available”

   pip install PyMuPDF
   

4. Drag and drop not working

   pip install tkinterdnd2
   

   Note: If tkinterdnd2 installation fails, you can still use the file browser button.

Performance Tips

• For large PDF files, operations may take some time
• The application shows progress indicators for long operations
• Operations run in separate threads to keep the UI responsive

Development

Code Structure

• SafePDFApp: Main application class handling UI and user interactions
• PDFOperations: Backend class with all PDF manipulation logic
• Modular design allows easy addition of new operations

Adding New Operations

1. Add operation logic to PDFOperations class
2. Create settings UI in SafePDFApp.update_settings_for_operation()
3. Add operation button in create_operation_tab()
4. Handle operation execution in _run_operation_thread()
