Installation

To use Docling, simply install docling from your package manager, e.g. pip:

pip install docling

Works on macOS, Linux and Windows environments. Both x86_64 and arm64 architectures.

More detailed installation instructions are available in the docs.

Getting started

To convert individual documents with python, use convert(), for example:

from docling.document_converter import DocumentConverter

source = "https://arxiv.org/pdf/2408.09869"  # document per local path or URL
converter = DocumentConverter()
result = converter.convert(source)
print(result.document.export_to_markdown())  # output: "## Docling Technical Report[...]"

More advanced usage options are available in the docs.

CLI

Docling has a built-in CLI to run conversions.

You can also use 🥚SmolDocling and other VLMs via Docling CLI:

docling --pipeline vlm --vlm-model smoldocling https://arxiv.org/pdf/2206.01062

This will use MLX acceleration on supported Apple Silicon hardware.
