# OpenDataLoader PDF

**Safe, Open, High-Performance — PDF for AI**

[OpenDataLoader PDF](https://github.com/opendataloader-project/opendataloader-pdf) converts PDFs into JSON, Markdown or Html — ready to feed into modern AI stacks (LLMs, vector search, and RAG).

It reconstructs document layout (headings, lists, tables, and reading order) so the content is easier to chunk, index, and query.
Powered by fast, heuristic, rule-based inference, it runs entirely on your local machine and delivers high-throughput processing for large document sets.
AI-safety is enabled by default and automatically filters likely prompt-injection content embedded in PDFs to reduce downstream risk.

)
documents = loader.load()

for doc in documents:
    print(doc.metadata, doc.page_content[:80])
```
