MarkItDown is a lightweight Python utility for converting various files to Markdown for use with LLMs and related text analysis pipelines. To this end, it is most comparable to textract, but with a focus on preserving important document structure and content as Markdown (including: headings, lists, tables, links, etc.) While the output is often reasonably presentable and human-friendly, it is meant to be consumed by text analysis tools -- and may not be the best option for high-fidelity document conversions for human consumption.
MarkItDown currently supports the conversion from:
- PDF
- PowerPoint
- Word
- Excel
- Images (EXIF metadata and OCR)
- Audio (EXIF metadata and speech transcription)
- HTML
- Text-based formats (CSV, JSON, XML)
- ZIP files (iterates over contents)
- YouTube URLs
- EPubs
- ... and more!
Why Markdown?
Markdown is extremely close to plain text, with minimal markup or formatting, but still
provides a way to represent important document structure. Mainstream LLMs, such as
OpenAI's GPT-4o, natively "_speak_" Markdown, and often incorporate Markdown into their
responses unprompted. This suggests that they have been trained on vast amounts of
Markdown-formatted text, and understand it well. As a side benefit, Markdown conventions
are also highly token-efficient.
Prerequisites
MarkItDown requires Python 3.10 through 3.14. It is recommended to use a virtual environment to avoid dependency conflicts.
With the standard Python installation, you can create and activate a virtual environment using the following commands:
If using uv, you can create a virtual environment with:
If you are using Anaconda, you can create a virtual environment with:
Installation
To install MarkItDown, use pip: pip install 'markitdown[all]'. Alternatively, you can install it from the source:
Usage
Command-Line
Or use -o to specify the output file:
You can also pipe content:
Optional Dependencies
MarkItDown has optional dependencies for activating various file formats. Earlier in this document, we installed all optional dependencies with the [all] option. However, you can also install them individually for more control. For example:
will install only the dependencies for PDF, DOCX, and PPTX files.
At the moment, the following optional dependencies are available:
* [all] Installs all optional dependencies
* [pptx] Installs dependencies for PowerPoint files
* [docx] Installs dependencies for Word files
* [xlsx] Installs dependencies for Excel files
* [xls] Installs dependencies for older Excel files
* [pdf] Installs dependencies for PDF files
* [outlook] Installs dependencies for Outlook messages
* [az-doc-intel] Installs dependencies for Azure Document Intelligence
* [az-content-understanding] Installs dependencies for Azure Content Understanding
* [audio-transcription] Installs dependencies for audio transcription of wav and mp3 files
* [youtube-transcription] Installs dependencies for fetching YouTube video transcription
Plugins
MarkItDown also supports 3rd-party plugins. Plugins are disabled by default. To list installed plugins:

To find available plugins, search GitHub for the hashtag #markitdown-plugin. To develop a plugin, see packages/markitdown-sample-plugin.
markitdown-ocr Plugin
The markitdown-ocr plugin adds OCR support to PDF, DOCX, PPTX, and XLSX converters, extracting text from embedded images using LLM Vision — the same llm_client / llm_model pattern that MarkItDown already uses for image descriptions. No new ML libraries or binary dependencies required.
