Pdfmux provides a comprehensive, self-healing solution for PDF data extraction, designed to eliminate silent data loss. It intelligently routes each page through an array of seven built-in extraction backends or custom LLM fallbacks, ensuring robust and high-quality data output suitable for RAG pipelines. A unique 'Certify Anything' feature allows auditing of any third-party PDF extractor's output, identifying and reporting pages that were silently dropped. This ensures the integrity and completeness of extracted data, preventing issues like 'poisoned' RAG indices.
