docling-slim 2.92.0

Modular version of the Docling package: SDK and CLI for parsing PDF, DOCX, HTML, and more, to a unified document representation for powering downstream workflows such as gen AI applications.

Docling Slim

Lightweight SDK for parsing documents with minimal dependencies and opt-in extras

Docling Slim is a minimal-dependency version of Docling that allows you to install only the components you need. It provides the core document processing functionality with ~50MB of base dependencies, and you can add specific features through optional extras.

When to Use Docling Slim

• Use docling (recommended): If you want the full-featured experience with all standard capabilities
• Use docling-slim: If you need fine-grained control over dependencies or want to minimize installation size

For Most Users: Use the Main Docling Package

We recommend most users install the full-featured docling package instead:

pip install docling

The docling package includes all standard features, the CLI tools, and is the easiest way to get started. Visit the main Docling documentation for complete guides and examples.
