DoclingTools enable an Agent to convert documents from multiple input formats (PDF, DOCX, PPTX, XLSX, HTML, images, audio, video, etc.) into output formats like Markdown, JSON, YAML, HTML, DocTags, and more using the Docling library.

​
Prerequisites

The following example requires the docling library. 
uv pip install -U docling

# Required for the OCR example
uv pip install -U easyocr

# Required for audio/video processing
uv pip install -U openai-whisper
ffmpeg is also required for audio/video processing:
  • macOS: brew install ffmpeg
  • Ubuntu: sudo apt-get install ffmpeg
  • Windows: Download from ffmpeg.org

​
Example

The following agent converts a PDF to Markdown: 
from agno.agent import Agent
from agno.tools.docling import DoclingTools

agent = Agent(
    tools=[DoclingTools(all=True)],
    description="You are an agent that converts documents from all Docling parsers and exports to all supported output formats.",
)

agent.print_response(
    "Convert to Markdown: cookbook/07_knowledge/testing_resources/cv_1.pdf",
    markdown=True,
)

​
OCR Configuration

Configure OCR settings for scanned PDFs or documents with embedded images.
cookbook/91_tools/docling_tools/ocr_example.py
from agno.agent import Agent
from agno.tools.docling import DoclingTools

ocr_tools = DoclingTools(
    pdf_enable_ocr=True,
    pdf_ocr_engine="easyocr",
    pdf_ocr_lang=["pt", "en"],
    pdf_force_full_page_ocr=True,
    pdf_enable_table_structure=True,
    pdf_enable_picture_description=False,
    pdf_document_timeout=120.0,
)

ocr_agent = Agent(
    tools=[ocr_tools],
    description="You are an agent that converts PDFs using advanced OCR.",
)

ocr_agent.print_response(
    "Convert to Markdown: cookbook/07_knowledge/testing_resources/cv_1.pdf",
    markdown=True,
)
