PDF to Markdown vs Mistral OCR
Mistral OCR is a strong multilingual OCR API that returns Markdown plus rich structural metadata, billed per page. pdf2md.dev is a hosted converter you can use free and anonymously – in the browser, by REST API, or from a hosted MCP. Here is an honest side-by-side.
Pay-per-page OCR API, or free hosted conversion
Choose Mistral OCR when you need rich structural metadata – bounding boxes, confidence scores, block labels – or its specific multilingual breadth, and you are fine paying per page with an API key. Choose pdf2md.dev when you want clean Markdown now with no key and no metering: a free anonymous browser tool, built-in OCR across many languages, real Markdown tables and formulas, and a REST API plus a hosted MCP any agent can call.

When Mistral OCR is the better choice
Mistral OCR is a capable, metadata-rich API. Reach for it when these fit.
Boxes & confidence
You need per-word or per-block bounding boxes and confidence scores, not just the final Markdown.
Document AI JSON
You want its Document AI structured-JSON annotations over the whole document as a separate output.
Specific languages
Its advertised multilingual breadth matches your languages and per-page billing is acceptable.
When pdf2md.dev fits better
No key, no per-page meter, nothing to install.
No API key
Convert anonymously in the browser on the free tier instead of provisioning a key and a billing account.
Flat, not per-page
Predictable tiers rather than per-page metering that adds up across large documents.
Hosted MCP for agents
Call a REST API or hosted MCP with no key to start, ready Markdown out.
Ready-to-use Markdown
Clean tables and formulas you can paste straight into a doc or a prompt – no post-processing of metadata.
Just want Markdown out?
If you do not need bounding boxes and confidence scores, pdf2md.dev returns clean Markdown from a REST API and a hosted MCP with no key and no per-page meter. See the RAG guide and the Python tutorial.
