Unlike traditional converters such as textract [(github.com in Bing)](https://www.bing.com/search?q="https%3A%2F%2Fgithub.com%2Fdeanmalmgren%2Ftextract"), MarkItDown emphasizes preserving document structure—headings, lists, tables, links—while producing output that is both token-efficient and LLM-friendly. -> [!IMPORTANT] -> MarkItDown performs I/O with the privileges of the current process. Like open() or requests.get(), it will access resources that the process itself can access. Sanitize your inputs in untrusted environments, and call the narrowest `convert_*` function needed for your use case (e.g., `convert_stream()`, or `convert_local()`). See the [Security Considerations](#security-considerations) section of the documentation for more information. +It currently supports conversion from: +- PDF, Word, PowerPoint, Excel (including legacy formats) +- Images (EXIF metadata + OCR) +- Audio (metadata + transcription) +- HTML, CSV, JSON, XML +- ZIP archives +- YouTube URLs +- EPubs +- And more -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](https://github.com/deanmalmgren/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: +## Why Markdown? +Markdown is close to plain text yet expressive enough to capture document hierarchy. Mainstream LLMs, including GPT‑4o, natively handle Markdown, making it an ideal format for efficient, structured text analysis. -- 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? +## Prerequisites +- Python 3.10+ +- Recommended: virtual environment (venv, uv, or Anaconda) to isolate dependencies -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 or higher. 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: - -```bash -python -m venv .venv -source .venv/bin/activate -``` - -If using `uv`, you can create a virtual environment with: - -```bash -uv venv --python=3.12 .venv -source .venv/bin/activate -# NOTE: Be sure to use 'uv pip install' rather than just 'pip install' to install packages in this virtual environment -``` - -If you are using Anaconda, you can create a virtual environment with: +--- +## Installation +Install via pip: ```bash -conda create -n markitdown python=3.12 -conda activate markitdown +pip install 'markitdown[all]' ``` - -## Installation - -To install MarkItDown, use pip: `pip install 'markitdown[all]'`. Alternatively, you can install it from the source: - + Or from source: ```bash git clone git@github.com:microsoft/markitdown.git cd markitdown pip install -e 'packages/markitdown[all]' ``` + +Optional dependencies can be installed selectively (e.g., `pip install 'markitdown[pdf, docx, pptx]'`). -## Usage +--- -### Command-Line +## Usage +### Command Line ```bash markitdown path-to-file.pdf > document.md -``` - -Or use `-o` to specify the output file: - -```bash markitdown path-to-file.pdf -o document.md -``` - -You can also pipe content: - -```bash cat path-to-file.pdf | markitdown ``` - -### 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: - -```bash -pip install 'markitdown[pdf, docx, pptx]' -``` - -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: - -```bash -markitdown --list-plugins -``` - -To enable plugins use: - -```bash -markitdown --use-plugins path-to-file.pdf -``` - -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. - -**Installation:** - -```bash -pip install markitdown-ocr -pip install openai # or any OpenAI-compatible client -``` - -**Usage:** - -Pass the same `llm_client` and `llm_model` you would use for image descriptions: - + +### Python API ```python from markitdown import MarkItDown -from openai import OpenAI - -md = MarkItDown( - enable_plugins=True, - llm_client=OpenAI(), - llm_model="gpt-4o", -) -result = md.convert("document_with_images.pdf") +md = MarkItDown(enable_plugins=False) +result = md.convert("test.xlsx") print(result.text_content) ``` + +Supports integration with Azure Document Intelligence and Azure Content Understanding for advanced cloud-based extraction, structured field parsing (YAML front matter), and multimodal analysis. -If no `llm_client` is provided the plugin still loads, but OCR is silently skipped and the standard built-in converter is used instead. - -See [`packages/markitdown-ocr/README.md`](packages/markitdown-ocr/README.md) for detailed documentation. - -### Azure Content Understanding - -[Azure Content Understanding](https://learn.microsoft.com/azure/ai-services/content-understanding/) provides higher-quality conversion with structured field extraction (YAML front matter), multi-modal support (documents, images, audio, video), and configurable analyzers. - -Install: `pip install 'markitdown[az-content-understanding]'` - -#### When to use Content Understanding - -Content Understanding is ideal when you need capabilities beyond what built-in or Document Intelligence converters provide: +--- -- **Audio and video files** — CU is the only option for video, and the higher-quality cloud option for audio. Built-in converters have no video support and only basic audio transcription. -- **Structured field extraction** — [Prebuilt](https://learn.microsoft.com/azure/ai-services/content-understanding/concepts/prebuilt-analyzers) or [custom-built](https://learn.microsoft.com/azure/ai-services/content-understanding/how-to/customize-analyzer-content-understanding-studio?tabs=portal) analyzers extract domain-specific fields (invoice amounts, receipt dates, contract clauses) serialized as YAML front matter. Neither built-in nor Doc Intel integration exposes fields. -- **Higher-quality document extraction** — Cloud-based layout analysis and OCR for scanned PDFs, complex tables, and multi-page documents. -- **Single API for all modalities** — One `cu_endpoint` handles documents, images, audio, and video with automatic analyzer routing. - -| Capability | Built-in converters | Azure Document Intelligence | Azure Content Understanding | -|------------|---------------------|-----------------------------|-----------------------------| -| Document conversion | Offline, format-specific extraction | Cloud layout extraction | Cloud multimodal extraction | -| Structured fields | Not available | Not exposed by this integration | YAML front matter from analyzer fields | -| Custom analyzers | Not available | Not configurable in this integration | Supported with `cu_analyzer_id` | -| Audio and video | Basic audio, no video | Not supported | Audio and video analyzers | -| Cost | Local compute only | Billable Azure API calls | Billable Azure API calls | - -**CLI:** +## Plugins +MarkItDown supports third‑party plugins (disabled by default).

Incompatible types (e.g., audio files with a document analyzer) auto-route to default prebuilt analyzers. - -**Cost note:** Each `convert()` call for a CU-routed format is a billable Azure API call. Use `cu_file_types` to restrict which formats route to CU: - -```python -from markitdown.converters import ContentUnderstandingFileType - -md = MarkItDown( - cu_endpoint="", - cu_file_types=[ContentUnderstandingFileType.PDF], # only PDFs use CU -) +markitdown --use-plugins path-to-file.pdf ``` + +--- -More information about Azure Content Understanding can be found [here](https://learn.microsoft.com/azure/ai-services/content-understanding/). - -### Azure Document Intelligence - -To use Microsoft Document Intelligence for conversion: - +## Docker ```bash -markitdown path-to-file.pdf -o document.md -d -e "" -``` - -More information about how to set up an Azure Document Intelligence Resource can be found [here](https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/how-to-guides/create-document-intelligence-resource?view=doc-intel-4.0.0) - -### Python API - -Basic usage in Python: - -```python -from markitdown import MarkItDown - -md = MarkItDown(enable_plugins=False) # Set to True to enable plugins -result = md.convert("test.xlsx") -print(result.text_content) -``` - -Document Intelligence conversion in Python: - -```python -from markitdown import MarkItDown - -md = MarkItDown(docintel_endpoint="") -result = md.convert("test.pdf") -print(result.text_content) -``` - -To use Large Language Models for image descriptions (currently only for pptx and image files), provide `llm_client` and `llm_model`: - -```python -from markitdown import MarkItDown -from openai import OpenAI - -client = OpenAI() -md = MarkItDown(llm_client=client, llm_model="gpt-4o", llm_prompt="optional custom prompt") -result = md.convert("example.jpg") -print(result.text_content) -``` - -### Docker - -```sh docker build -t markitdown:latest . docker run --rm -i markitdown:latest < ~/your-file.pdf > output.md ``` + +--- -## Contributing - -This project welcomes contributions and suggestions.

- -### Running Tests and Checks - -- Navigate to the MarkItDown package: - - ```sh - cd packages/markitdown - ``` - -- Install `hatch` in your environment and run tests: - - ```sh - pip install hatch # Other ways of installing hatch: https://hatch.pypa.io/dev/install/ - hatch shell - hatch test - ``` - - (Alternative) Use the Devcontainer which has all the dependencies installed: - - ```sh - # Reopen the project in Devcontainer and run: - hatch test - ``` - -- Run pre-commit checks before submitting a PR: `pre-commit run --all-files` - -### Security Considerations - -MarkItDown performs I/O with the privileges of the current process. Like `open()` or `requests.get()`, it will access resources that the process itself can access. - -**Sanitize your inputs:** Do not pass untrusted input directly to MarkItDown. If any part of the input may be controlled by an untrusted user or system, such as in hosted or server-side applications, it must be validated and restricted before calling MarkItDown. Depending on your environment, this may include restricting file paths, limiting URI schemes and network destinations, and blocking access to private, loopback, link-local, or metadata-service addresses. - -**Call only the conversion method you need:** Prefer the narrowest conversion API that fits your use case. MarkItDown's `convert()` method is intentionally permissive and can handle local files, remote URIs, and byte streams. If your application only needs to read local files, call `convert_local()` instead. If you need more control over URI fetching, call `requests.get()` yourself and pass the response object to `convert_response()`. For maximum control, open a stream to the input you want converted and call `convert_stream()`. - -### Contributing 3rd-party Plugins +## Contributing +Contributions are welcome.
