How to Convert Various Documents to Markdown?
Word / PDF / PPT One-Click Conversion Guide

Why convert documents to Markdown?

Markdown is close to plain text, yet uses simple symbols to express headings, lists, tables, links, and more. It has several clear advantages:

• AI-friendly: GPT, Claude, and other major AIs natively "speak" Markdown. Feeding them .md gives better results and saves tokens;
• Long-term readable: Plain text won't become unreadable when software versions change — it'll still open in Notepad ten years from now;
• Easy to manage: Git version control, full-text search, and cross-platform sync are all straightforward;
• Small size: The same document as .md can be ten times smaller than .docx.

Method 1: markitdown (Microsoft open source, most recommended)

markitdown is an open-source Python tool from Microsoft's AutoGen team, built for one thing: converting various files to Markdown.

It supports a very wide range of formats:

• PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx)
• Images (EXIF metadata + OCR text recognition)
• Audio (transcription)
• HTML, CSV, JSON, XML
• EPub e-books, ZIP archives (automatically traverses contents)
• YouTube video links (auto-extracts subtitles)

One tool covers almost all common formats, and it runs entirely locally — free and open source.

Installation

Requires Python 3.10 or higher. It's recommended to create a virtual environment first:

python -m venv .venv
.venv\Scripts\activate    # Windows
# source .venv/bin/activate  # macOS / Linux

Then install markitdown:

pip install "markitdown[all]"

[all] installs all optional dependencies (PDF, Office, audio transcription, etc.). If you only need specific formats, install selectively, e.g. pip install "markitdown[pdf,docx,pptx]".

Command-line usage

The most basic usage is just one line:

markitdown document.pdf -o document.md

Pipes are also supported:

cat document.docx | markitdown > document.md

For batch conversion, combine with a for loop to process an entire folder:

# Windows PowerShell
Get-ChildItem *.docx | ForEach-Object { markitdown $_.Name -o "$($_.BaseName).md" }

# macOS / Linux
for f in *.docx; do markitdown "$f" -o "${f%.docx}.md"; done

Python API usage

If you want to call it from a script or integrate it into your own project:

from markitdown import MarkItDown

md = MarkItDown()
result = md.convert("document.pdf")
print(result.text_content)

# Save to file
with open("document.md", "w", encoding="utf-8") as f:
    f.write(result.text_content)

If you want to use a large model to generate image descriptions (for example, screenshots in a PPT), you can pass in an LLM client:

from markitdown import MarkItDown
from openai import OpenAI

md = MarkItDown(
    llm_client=OpenAI(),
    llm_model="gpt-4o",
)
result = md.convert("presentation.pptx")
print(result.text_content)

Method 2: Pandoc (command-line swiss army knife)

Pandoc is a veteran document conversion tool, often called the "universal converter between formats." It especially shines with Office documents and LaTeX.

# Word to Markdown
pandoc document.docx -o document.md

# PPT to Markdown
pandoc presentation.pptx -o presentation.md

# EPub to Markdown
pandoc book.epub -o book.md

Pandoc's strengths are high conversion quality and strong customization, but its weakness is that it doesn't support PDF to Markdown (PDF conversion requires extra LaTeX engine setup, which is complex).

Method 3: Online conversion tools

Search "Word to Markdown" or "PDF to Markdown" in your browser and you'll find plenty of online tools. The usual flow is upload file → download the converted result.

• Pros: no installation, works in any browser;
• Cons: you have to upload files to a third-party server, which isn't suitable for sensitive documents; local images may be lost; format fidelity varies.

Good for temporary conversion of one or two non-sensitive documents.

Method 4: Copy and paste

If the document is short and simple, the easiest way might be:

• Select all in Word / PPT → copy;
• Paste into a .md file;
• Manually add Markdown markers like # for headings and - for lists.

Works for short documents with just a few paragraphs. Once the content grows or tables get complex, manual cleanup becomes tedious.

Conversion tips by format

Word (.docx) → Markdown

This is the most common conversion need. markitdown is recommended because it preserves heading hierarchy, lists, tables, links, and other structure. Pandoc is also a good choice.

PDF → Markdown

PDF conversion falls into two cases:

• Text-based PDF (where text is selectable): markitdown converts it directly with good results;
• Scanned PDF (image-based): requires OCR. markitdown can work with the LLM Vision plugin (markitdown-ocr), or you can use a dedicated OCR tool to extract text first.

PowerPoint (.pptx) → Markdown

markitdown extracts content slide by slide, turning each slide into a Markdown section. Text, lists, and tables are preserved. Images in the PPT can be described with an LLM.

Excel (.xlsx) → Markdown

Excel tables are converted directly into Markdown table syntax. markitdown handles this well, and simple tables usually need little to no manual adjustment.

Images → Markdown

markitdown can extract EXIF info from images (capture time, location, device, etc.), and with an LLM it can also generate descriptions of image content. If you need to extract text from screenshots, install the markitdown-ocr plugin.

Comparison of the four methods

After converting to Markdown, how do you read it?

Once documents are converted into a pile of .md files, the next question is how to open and read them.

We recommend mdview:

• Double-click to open: after installation, it associates .md files so you can double-click to enter the reader;
• Auto outline: long documents automatically get a sidebar outline, click a heading to jump;
• Fully local: no files are uploaded, open to view and close to finish;
• Windows + Android: both platforms are supported, so you can read anywhere after conversion.

After all, the whole point of converting to Markdown is to read and manage content more easily. A handy viewer makes the whole flow smoother.

Summary

If you often need to convert documents to Markdown, markitdown is the most worry-free choice: one command, covers almost every format, maintained by Microsoft, completely free. Paired with mdview as a viewer, the experience from conversion to reading is smooth.

For occasional one-off use, online tools or copy-paste are enough. Pandoc is for advanced users who need higher conversion quality and don't mind the command line.
