What is markdown-converter?

A command-line converter that turns files and web content into Markdown, a plain-text format commonly used for documentation and code notes. It supports documents, spreadsheets, presentations, web data, images, audio, ZIP files, EPUBs, and YouTube URLs.

Use it to convert PDFs, Word files, Excel sheets, PowerPoint slides, HTML, CSV, JSON, XML, images, audio, archives, EPUBs, and YouTube pages into Markdown.

It removes the need to manually copy content from different file types into Markdown and can process input from a file or standard input.

SkillSpector: 10 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.00572
Opus 5.5	$0.00010	$0.00229
Sonnet 5.5	$0.00005	$0.00114
Haiku 4.5	$0.00002	$0.00057

Security

Grade A, and why

markdown-converter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Markdown Converter

Convert files to Markdown using uvx --from "markitdown[all]" markitdown — no installation required.

Basic Usage

# Convert to stdout
uvx --from "markitdown[all]" markitdown input.pdf

# Save to file
uvx --from "markitdown[all]" markitdown input.pdf -o output.md
uvx --from "markitdown[all]" markitdown input.docx > output.md

# From stdin
cat input.pdf | uvx --from "markitdown[all]" markitdown

Supported Formats

Documents: PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx, .xls)
Web/Data: HTML, CSV, JSON, XML
Media: Images (EXIF + OCR), Audio (EXIF + transcription)
Other: ZIP (iterates contents), YouTube URLs, EPub

Options

-o OUTPUT      # Output file
-x EXTENSION   # Hint file extension (for stdin)
-m MIME_TYPE   # Hint MIME type
-c CHARSET     # Hint charset (e.g., UTF-8)
-d             # Use Azure Document Intelligence
-e ENDPOINT    # Document Intelligence endpoint
--use-plugins  # Enable 3rd-party plugins
--list-plugins # Show installed plugins

Examples

# Convert Word document
uvx --from "markitdown[all]" markitdown report.docx -o report.md

# Convert Excel spreadsheet
uvx --from "markitdown[all]" markitdown data.xlsx > data.md

# Convert PowerPoint presentation
uvx --from "markitdown[all]" markitdown slides.pptx -o slides.md

# Convert with file type hint (for stdin)
cat document | uvx --from "markitdown[all]" markitdown -x .pdf > output.md

# Use Azure Document Intelligence for better PDF extraction
uvx --from "markitdown[all]" markitdown scan.pdf -d -e "https://your-resource.cognitiveservices.azure.com/"

Notes

Output preserves document structure: headings, tables, lists, links
First run caches dependencies; subsequent runs are faster
For complex PDFs with poor extraction, use -d with Azure Document Intelligence
If automatic charset detection picks the wrong encoding for a text file, pass -c UTF-8 (or the known charset)

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
