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, 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.

Apify Actor

You can run Docling in the cloud without installation using the Docling Actor on Apify platform. Simply provide a document URL and get the processed result:

apify call vancura/docling -i '{
  "options": {
    "to_formats": ["md", "json", "html", "text", "doctags"]
  },
  "http_sources": [
    {"url": "https://vancura.dev/assets/actor-test/facial-hairstyles-and-filtering-facepiece-respirators.pdf"},
    {"url": "https://arxiv.org/pdf/2408.09869"}
  ]
}'

The Actor stores results in:

• Processed document in key-value store (OUTPUT_RESULT)
• Processing logs (DOCLING_LOG)
• Dataset record with result URL and status
