Limitations and Best Practices

Be mindful of the following:

• File type compatibility: Ensure the source file is either scanned or text-based before using OCR or extraction tools.
• Backup original files: Always keep a copy of the original document, especially when modifying pages, rotating them, or applying passwords.
• Temporary processing: Files are handled temporarily and not stored permanently, so avoid saving them unless necessary.
