OpenDataLoader PDF is an open-source tool for parsing PDFs and auto-tagging unstructured PDFs into screen-reader-ready Tagged PDFs. It offers multiple output formats (JSON, Markdown, HTML, Annotated PDF, Text), two processing engines (heuristic at 60+ pages/sec on CPU, and hybrid AI mode for complex documents), and configurable options for table detection, noise filtering, and reading order via the XY-Cut++ algorithm. The heuristic engine achieves 0.91 reading order accuracy; hybrid AI mode improves this to 0.934 and boosts table accuracy from 0.49 to 0.93. JSON output with bounding boxes targets RAG pipelines, while Markdown suits human readability. Auto-tagging is Apache 2.0 licensed; full PDF/UA-1 and PDF/UA-2 export is an enterprise add-on.
