> [!IMPORTANT]
> Breaking changes between 0.0.1 to 0.1.0:
> * Dependencies are now organized into optional feature-groups (further details below). Use `pip install 'markitdown[all]'` to have backward-compatible behavior.
> * convert\_stream() now requires a binary file-like object (e.g., a file opened in binary mode, or an io.BytesIO object). This is a breaking change from the previous version, where it previously also accepted text file-like objects, like io.StringIO.
> * The DocumentConverter class interface has changed to read from file-like streams rather than file paths. *No temporary files are created anymore*. If you are the maintainer of a plugin, or custom DocumentConverter, you likely need to update your code. Otherwise, if only using the MarkItDown class or CLI (as in these examples), you should not need to change anything.
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.

## 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 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:
```bash
conda create -n markitdown python=3.12
conda activate markitdown
```
## Installation
To install MarkItDown, use pip: `pip install 'markitdown[all]'`. Alternatively, you can install it from the source:
```bash
git clone git@github.com:microsoft/markitdown.git
cd markitdown
pip install -e 'packages/markitdown[all]'
```
To install MarkItDown, use pip: `pip install markitdown`. Alternatively, you can install it from the source: `pip install -e .`
## Usage

markitdown path-to-file.pdf -o document.md
```
To use Document Intelligence conversion:
```bash
markitdown path-to-file.pdf -o document.md -d -e "<document_intelligence_endpoint>"
```
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
* `[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
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")
print(result.text_content)
```
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 Document Intelligence
To use Microsoft Document Intelligence for conversion:
```bash
markitdown path-to-file.pdf -o document.md -d -e "<document_intelligence_endpoint>"
```

# MarkItDown-MCP
> [!IMPORTANT]
> The MarkItDown-MCP package is meant for **local use**, with local trusted agents. In particular, when running the MCP server with Streamable HTTP or SSE, it binds to `localhost` by default, and is not exposed to other machines on the network or Internet. In this configuration, it is meant to be a direct alternative to the STDIO transport, which may be more convenient in some cases. DO NOT bind the server to other interfaces unless you understand the [security implications](#security-considerations) of doing so.
[![PyPI](https://img.shields.io/pypi/v/markitdown-mcp.svg)](https://pypi.org/project/markitdown-mcp/)
![PyPI - Downloads](https://img.shields.io/pypi/dd/markitdown-mcp)
[![Built by AutoGen Team](https://img.shields.io/badge/Built%20by-AutoGen%20Team-blue)](https://github.com/microsoft/autogen)
The `markitdown-mcp` package provides a lightweight STDIO, Streamable HTTP, and SSE MCP server for calling MarkItDown.
It exposes one tool: `convert_to_markdown(uri)`, where uri can be any `http:`, `https:`, `file:`, or `data:` URI.
## Installation
To install the package, use pip:
```bash
pip install markitdown-mcp
```
## Usage
To run the MCP server, using STDIO (default), use the following command:
```bash
markitdown-mcp
```
To run the MCP server, using Streamable HTTP and SSE, use the following command:
```bash
markitdown-mcp --http --host 127.0.0.1 --port 3001
```
## Running in Docker
To run `markitdown-mcp` in Docker, build the Docker image using the provided Dockerfile:
```bash
docker build -t markitdown-mcp:latest .
```
And run it using:
```bash
docker run -it --rm markitdown-mcp:latest
```
This will be sufficient for remote URIs. To access local files, you need to mount the local directory into the container. For example, if you want to access files in `/home/user/data`, you can run:
```bash
docker run -it --rm -v /home/user/data:/workdir markitdown-mcp:latest
```
Once mounted, all files under data will be accessible under `/workdir` in the container. For example, if you have a file `example.txt` in `/home/user/data`, it will be accessible in the container at `/workdir/example.txt`.
## Accessing from Claude Desktop
It is recommended to use the Docker image when running the MCP server for Claude Desktop.
Follow [these instructions](https://modelcontextprotocol.io/quickstart/user#for-claude-desktop-users) to access Claude's `claude_desktop_config.json` file.
Edit it to include the following JSON entry:
```json
{
"mcpServers": {
"markitdown": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"markitdown-mcp:latest"
]
}
}
}
```
If you want to mount a directory, adjust it accordingly:
```json
{
"mcpServers": {
"markitdown": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-v",
"/home/user/data:/workdir",
"markitdown-mcp:latest"
]
}
}
}
```
## Debugging
To debug the MCP server you can use the `MCP Inspector` tool.
```bash
npx @modelcontextprotocol/inspector
```
You can then connect to the inspector through the specified host and port (e.g., `http://localhost:5173/`).
If using STDIO:
* select `STDIO` as the transport type,
* input `markitdown-mcp` as the command, and
* click `Connect`
If using Streamable HTTP:
* select `Streamable HTTP` as the transport type,
* input `http://127.0.0.1:3001/mcp` as the URL, and
* click `Connect`
If using SSE:
* select `SSE` as the transport type,
* input `http://127.0.0.1:3001/sse` as the URL, and
* click `Connect`
Finally:
* click the `Tools` tab,
* click `List Tools`,
* click `convert_to_markdown`, and
* run the tool on any valid URI.
## Security Considerations
The server does not support authentication, and runs with the privileges of the user running it. For this reason, when running in SSE or Streamable HTTP mode, the server binds by default to `localhost`. Even still, it is important to recognize that the server can be accessed by any process or users on the same local machine, and that the `convert_to_markdown` tool can be used to read any file that the server's user has access to, or any data from the network. If you require additional security, consider running the server in a sandboxed environment, such as a virtual machine or container, and ensure that the user permissions are properly configured to limit access to sensitive files and network segments. Above all, DO NOT bind the server to other interfaces (non-localhost) unless you understand the security implications of doing so.

# MarkItDown OCR Plugin
LLM Vision plugin for MarkItDown that extracts text from images embedded in PDF, DOCX, PPTX, and XLSX files.
Uses the same `llm_client` / `llm_model` pattern that MarkItDown already supports for image descriptions — no new ML libraries or binary dependencies required.
## Features
- **Enhanced PDF Converter**: Extracts text from images within PDFs, with full-page OCR fallback for scanned documents
- **Enhanced DOCX Converter**: OCR for images in Word documents
- **Enhanced PPTX Converter**: OCR for images in PowerPoint presentations
- **Enhanced XLSX Converter**: OCR for images in Excel spreadsheets
- **Context Preservation**: Maintains document structure and flow when inserting extracted text
## Installation
```bash
pip install markitdown-ocr
```
The plugin uses whatever OpenAI-compatible client you already have. Install one if you don't have it yet:
```bash
pip install openai
```
## Usage
### Command Line
```bash
markitdown document.pdf --use-plugins --llm-client openai --llm-model gpt-4o
```
### Python API
Pass `llm_client` and `llm_model` to `MarkItDown()` exactly as you would for image descriptions:
```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")
print(result.text_content)
```
If no `llm_client` is provided the plugin still loads, but OCR is silently skipped — falling back to the standard built-in converter.
### Custom Prompt
Override the default extraction prompt for specialized documents:
```python
md = MarkItDown(
enable_plugins=True,
llm_client=OpenAI(),
llm_model="gpt-4o",
llm_prompt="Extract all text from this image, preserving table structure.",
)
```
### Any OpenAI-Compatible Client
Works with any client that follows the OpenAI API:
```python
from openai import AzureOpenAI
md = MarkItDown(
enable_plugins=True,
llm_client=AzureOpenAI(
api_key="...",
azure_endpoint="https://your-resource.openai.azure.com/",
api_version="2024-02-01",
),
llm_model="gpt-4o",
)
```
## How It Works
When `MarkItDown(enable_plugins=True, llm_client=..., llm_model=...)` is called:
1. MarkItDown discovers the plugin via the `markitdown.plugin` entry point group
2. It calls `register_converters()`, forwarding all kwargs including `llm_client` and `llm_model`
3. The plugin creates an `LLMVisionOCRService` from those kwargs
4. Four OCR-enhanced converters are registered at **priority -1.0** — before the built-in converters at priority 0.0
When a file is converted:
1. The OCR converter accepts the file
2. It extracts embedded images from the document
3. Each image is sent to the LLM with an extraction prompt
4. The returned text is inserted inline, preserving document structure
5. If the LLM call fails, conversion continues without that image's text
## Supported File Formats
### PDF
- Embedded images are extracted by position (via `page.images` / page XObjects) and OCR'd inline, interleaved with the surrounding text in vertical reading order.
- **Scanned PDFs** (pages with no extractable text) are detected automatically: each page is rendered at 300 DPI and sent to the LLM as a full-page image.
- **Malformed PDFs** that pdfplumber/pdfminer cannot open (e.g. truncated EOF) are retried with PyMuPDF page rendering, so content is still recovered.
### DOCX
- Images are extracted via document part relationships (`doc.part.rels`).
- OCR is run before the DOCX→HTML→Markdown pipeline executes: placeholder tokens are injected into the HTML so that the markdown converter does not escape the OCR markers, and the final placeholders are replaced with the formatted `*[Image OCR]...[End OCR]*` blocks after conversion.
- Document flow (headings, paragraphs, tables) is fully preserved around the OCR blocks.
### PPTX
- Picture shapes, placeholder shapes with images, and images inside groups are all supported.
- Shapes are processed in top-to-left reading order per slide.
- If an `llm_client` is configured, the LLM is asked for a description first; OCR is used as the fallback when no description is returned.
### XLSX
- Images embedded in worksheets (`sheet._images`) are extracted per sheet.
- Cell position is calculated from the image anchor coordinates (column/row → Excel letter notation).
- Images are listed under a `### Images in this sheet:` section after the sheet's data table — they are not interleaved into the table rows.
### Output format
Every extracted OCR block is wrapped as:
```text
*[Image OCR]
<extracted text>
[End OCR]*
```
## Troubleshooting
### OCR text missing from output
The most likely cause is a missing `llm_client` or `llm_model`. Verify:
```python
from openai import OpenAI
from markitdown import MarkItDown
md = MarkItDown(
enable_plugins=True,
llm_client=OpenAI(), # required
llm_model="gpt-4o", # required
)
```
### Plugin not loading
Confirm the plugin is installed and discovered:
```bash
markitdown --list-plugins # should show: ocr
```
### API errors
The plugin propagates LLM API errors as warnings and continues conversion. Check your API key, quota, and that the chosen model supports vision inputs.
## Development
### Running Tests
```bash
cd packages/markitdown-ocr
pytest tests/ -v
```
### Building from Source
```bash
git clone https://github.com/microsoft/markitdown.git
cd markitdown/packages/markitdown-ocr
pip install -e .
```

# MarkItDown Sample Plugin
[![PyPI](https://img.shields.io/pypi/v/markitdown-sample-plugin.svg)](https://pypi.org/project/markitdown-sample-plugin/)
![PyPI - Downloads](https://img.shields.io/pypi/dd/markitdown-sample-plugin)
[![Built by AutoGen Team](https://img.shields.io/badge/Built%20by-AutoGen%20Team-blue)](https://github.com/microsoft/autogen)
This project shows how to create a sample plugin for MarkItDown. The most important parts are as follows:
Next, implement your custom DocumentConverter:
```python
from typing import BinaryIO, Any
from markitdown import MarkItDown, DocumentConverter, DocumentConverterResult, StreamInfo
class RtfConverter(DocumentConverter):
def __init__(
self, priority: float = DocumentConverter.PRIORITY_SPECIFIC_FILE_FORMAT
):
super().__init__(priority=priority)
def accepts(
self,
file_stream: BinaryIO,
stream_info: StreamInfo,
**kwargs: Any,
) -> bool:
# Implement logic to check if the file stream is an RTF file
# ...
raise NotImplementedError()
def convert(
self,
file_stream: BinaryIO,
stream_info: StreamInfo,
**kwargs: Any,
) -> DocumentConverterResult:
# Implement logic to convert the file stream to Markdown
# ...
raise NotImplementedError()
```
Next, make sure your package implements and exports the following:
```python
# The version of the plugin interface that this plugin uses.
# The only supported version is 1 for now.
__plugin_interface_version__ = 1
# The main entrypoint for the plugin. This is called each time MarkItDown instances are created.
def register_converters(markitdown: MarkItDown, **kwargs):
"""
Called during construction of MarkItDown instances to register converters provided by plugins.
"""
# Simply create and attach an RtfConverter instance
markitdown.register_converter(RtfConverter())
```
Finally, create an entrypoint in the `pyproject.toml` file:
```toml
[project.entry-points."markitdown.plugin"]
sample_plugin = "markitdown_sample_plugin"
```
Here, the value of `sample_plugin` can be any key, but should ideally be the name of the plugin. The value is the fully qualified name of the package implementing the plugin.
## Installation
To use the plugin with MarkItDown, it must be installed. To install the plugin from the current directory use:
```bash
pip install -e .
```
Once the plugin package is installed, verify that it is available to MarkItDown by running:
```bash
markitdown --list-plugins
```
To use the plugin for a conversion use the `--use-plugins` flag. For example, to convert an RTF file:
```bash
markitdown --use-plugins path-to-file.rtf
```
In Python, plugins can be enabled as follows:
```python
from markitdown import MarkItDown
md = MarkItDown(enable_plugins=True)
result = md.convert("path-to-file.rtf")
print(result.text_content)
```

Return a quick determination on if the converter should attempt converting the document.
This is primarily based `stream_info` (typically, `stream_info.mimetype`, `stream_info.extension`).
In cases where the data is retrieved via HTTP, the `steam_info.url` might also be referenced to
make a determination (e.g., special converters for Wikipedia, YouTube etc).
Finally, it is conceivable that the `stream_info.filename` might be used to in cases
where the filename is well-known (e.g., `Dockerfile`, `Makefile`, etc)
NOTE: The method signature is designed to match that of the convert() method. This provides some
assurance that, if accepts() returns True, the convert() method will also be able to handle the document.
IMPORTANT: In rare cases, (e.g., OutlookMsgConverter) we need to read more from the stream to make a final
determination. Read operations inevitably advances the position in file_stream. In these case, the position
MUST be reset it MUST be reset before returning. This is because the convert() method may be called immediately
after accepts(), and will expect the file_stream to be at the original position.
E.g.,
cur_pos = file_stream.tell() # Save the current position
data = file_stream.read(100) # ... peek at the first 100 bytes, etc.
file_stream.seek(cur_pos) # Reset the position to the original position
Parameters:
- file_stream: The file-like object to convert. Must support seek(), tell(), and read() methods.
- stream_info: The StreamInfo object containing metadata about the file (mimetype, extension, charset, set)
- kwargs: Additional keyword arguments for the converter.
Returns:
- bool: True if the converter can handle the document, False otherwise.
