About

MuPDF4LLM.NET provides LLM/RAG helpers for MuPDF.NET: PDF-to-Markdown conversion, layout parsing, and document structure analysis. It is designed for use with RAG (Retrieval-Augmented Generation) pipelines and integration with LLMs.

Documentation: docs.pdf4llm.com · .NET installation

This package extends MuPDF.NET with:

  • PDF-to-Markdown — Convert PDF pages to Markdown with layout awareness (tables, headers, images)
  • Layout parsing — Extract document structure (pages, boxes, tables, images) as JSON or structured objects
  • LlamaIndex integration — PDFMarkdownReader for compatibility with LlamaIndex document loading
  • OCR support — Optional OCR for scanned or image-heavy pages
  • Form fields — Extract key/value pairs from interactive PDF forms

Install with dotnet add package MuPDF4LLM.NET. MuPDF.NET is installed automatically as a dependency.

For Office/HWP documents (DOC/DOCX, XLS/XLSX, PPT/PPTX, HWP/HWPX), also install MuPDFOffice.NET, call MuPDFOffice.Unlock(...), then pass those paths to MuPDF4LLM.ToMarkdown / MuPDF4LLM.ToJson / MuPDF4LLM.ToText.

PyMuPDF Layout (optional)

AI-based page layout uses the Python package pymupdf-layout via an external worker. Install it once per machine:

dotnet msbuild -t:MuPDF4LLMNetSetupLayoutPython

This creates a per-user Python venv (Windows: %LOCALAPPDATA%\MuPDF4LLM.NET\.venv-layout, Linux/macOS: ~/.local/share/mupdf4llm.net/.venv-layout) and installs pinned pymupdf / pymupdf-layout wheels. MuPDF4LLM.NET discovers that venv automatically.

On Debian/Ubuntu, install system packages first:

sudo apt install python3-venv python3-pip

Alternatively, install pymupdf-layout into any Python 3.10+ environment and set MuPDF4LLM_NET_PYTHON to that interpreter. If layout is unavailable, MuPDF4LLM.NET falls back to classic text extraction.

Project-local venv: run python path/to/setup_layout_python.py --venv .mupdf4llm-net-venv in your project directory (also auto-discovered).
