PDF to Markdown vs MarkItDown
Microsoft MarkItDown is a handy MIT-licensed Python library that converts many file formats to Markdown. pdf2md.dev is a hosted converter with built-in OCR and real table reconstruction – in the browser, by REST API, or from a hosted MCP. Here is an honest side-by-side.
A local many-format library, or hosted OCR + tables
Choose MarkItDown when you want a small, free MIT library inside your own Python code to convert already-digital files – PDF, DOCX, XLSX, PPTX and a dozen more – and you do not need OCR or heavy table work. Choose pdf2md.dev when your PDFs are scanned or table-heavy: OCR is built in across many languages, tables are rebuilt into real Markdown with MinerU or Docling, and there is nothing to install – just the browser, a REST API or a hosted MCP.
pdf2md.dev vs MarkItDown, feature by feature
Both produce Markdown for LLM pipelines. The difference is built-in OCR and table reconstruction versus a lightweight local library.
| pdf2md.dev | MarkItDown | |
|---|---|---|
| Shape | Hosted service – browser, REST API or hosted MCP | Local Python library (MIT) |
| Setup | Nothing to install | pip install markitdown + Python |
| Built-in OCR | Yes, many languages, no flags | No – needs the markitdown-ocr plugin + an LLM Vision API; can't read un-OCR'd PDFs |
| Tables | Real reconstructed Markdown tables (MinerU / Docling) | Limited – XML parsing, no table-structure model; complex tables weak |
| Layout & formatting | Headings, lists and columns rebuilt | Strips formatting; multi-column imperfect |
| Input formats | PDF and images | PDF, DOCX, XLSX, PPTX and 12+ formats |
| Cost | Free anonymous tier; paid tiers raise limits | Free (MIT); OCR plugin adds LLM API cost |
| Hardware | None – we host it | Local CPU; OCR via an external LLM API |
| Automation | REST API + hosted MCP | Python library |
MarkItDown details from its public project documentation; pdf2md.dev values are the current free-tier limits. Both evolve – check each source for the latest.

When MarkItDown is the better choice
MarkItDown is a neat, lightweight tool. Reach for it when these fit.
A tiny local library
You want a free MIT dependency embedded directly in your own Python code, with no service in the path.
Many Office formats
You mostly convert already-digital DOCX, XLSX, PPTX and other formats, not scanned PDFs.
Fully local, simple docs
Your files are already digital and clean, so you do not need OCR or complex table reconstruction.
When pdf2md.dev fits better
The hard parts of real PDFs – scans, tables, layout – handled for you.
Real OCR, no LLM key
Scanned and image-only PDFs are read out of the box, without wiring up an LLM Vision API.
Tables done properly
Complex tables and multi-column pages are rebuilt into aligned Markdown, not flattened.
Formulas kept
Mathematical notation survives instead of scrambling into garbled characters.
Nothing to install
Convert in the browser, or call a REST API and hosted MCP – no Python environment to manage.
Want it in code anyway?
If you like MarkItDown for its library shape but need real OCR and tables, pdf2md.dev gives you the same in-code convenience through a REST API and a hosted MCP – no GPU, no LLM Vision key. See the Python tutorial.
Common questions
Does MarkItDown do OCR?
Not by itself. The core library cannot read PDFs that lack prior OCR; OCR comes from the separate markitdown-ocr plugin, which calls an LLM Vision API such as GPT-4o and adds cost. pdf2md.dev has OCR built in across many languages with nothing to wire up.
How well does MarkItDown handle tables?
It uses XML parsing rather than a table-structure model, so complex tables with merged cells, nested headers or multi-column layouts are limited. pdf2md.dev rebuilds real, aligned Markdown tables with MinerU or Docling.
Is MarkItDown free?
Yes. It is open-source under the MIT license and free to self-host. You pay only if you add the OCR plugin's LLM API calls. pdf2md.dev is free to use anonymously in the browser, with paid tiers for higher limits.
When should I use MarkItDown instead?
When you want a small local library inside your own Python code, mostly convert already-digital Office files across many formats (DOCX, XLSX, PPTX and more), and do not need OCR or heavy table reconstruction.
Do I need to install anything for pdf2md.dev?
No. It is hosted: convert in the browser, by REST API or hosted MCP. MarkItDown is a Python library you install and run yourself.
Which is better for scanned PDFs?
pdf2md.dev, because OCR is built in. MarkItDown needs the OCR plugin and an external LLM Vision key to read scanned or image-only pages – see converting scanned PDFs.
