Safe Open High-Performance
OpenDataLoader-PDF safely and accurately converts PDFs to JSON, Markdown, or HTML.
Easily feed them into AI stacks like LLM, vector search, and RAG!
About
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.

AI Safety
Defends against indirect prompt injection hiding inside PDFs before content reaches your agents.
- Hidden or transparent text planted inside the page.
- Off-page or overlapping elements that only models can see.
- Tiny fonts, OCG layers, or steganographic images carrying prompts.
hidden-text
Blocks invisible or low-contrast text.
On
off-page
Drops content outside the visible CropBox.
On
tiny
Filters sub-pixel fonts and microscopic text.

hidden-ocg
Removes prompts hidden in OCG layers.

Tagged PDF
A semantic, accessible PDF structure that makes documents AI-ready and easier to validate.
Growing accessibility requirements (like the European Accessibility Act) are accelerating adoption. Proper tags also turn unstructured documents into reliable, machine-readable data for AI workflows.
OpenDataLoader-PDF is building an engine that uses these tags to produce richer, safer extractions.
- Research papers: identify authors, affiliations, and headings for precise citations.
- Financial reports: keep balance-sheet titles tied to the right table cells.
- Legal contracts: surface clauses, dates, and parties for faster review.
