> * Dependencies are now organized into optional feature-groups (further details below). Use `pip install markitdown[all]` to have backward-compatible behavior.
> * 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 utility for converting various files to Markdown (e.g., for indexing, text analysis, etc). It is comparable to [Apache Tika](https://tika.apache.org/) or [Azure Document Intelligence](https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/overview?tabs=doc-intel-4.0.0), but can perform many simple operations locally, without a server or subscription. While the output is often reasonably presentable and human-friendly, it is meant to be consumed by text analysis tools. MarkItDown may not be the best option for high-fidelity document conversions for publication or document sharing, etc.
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
