Convert Any File
into Markdown for AI

MarkItDown began as Microsoft's open-source utility for converting files from many formats into clean, structured Markdown. Originally developed as a Python library, it supports PDF, DOCX, XLSX, PPTX, HTML, images, audio, CSV, JSON, XML, and many other file types. The online converter on this site is an independent tool inspired by it, giving you the same file-to-Markdown workflow directly in your browser without installing anything.

markitdown supports a wide range of file formats including PDF documents, Microsoft Word files (DOCX), Excel spreadsheets (XLSX), PowerPoint presentations (PPTX), HTML web pages, plain text files (TXT), CSV and TSV data files, JSON, and XML. The converter uses format-specific parsers so headings, tables, links, lists, and readable sections are handled as accurately as possible.

Yes. Microsoft's original MarkItDown library is open-source under the MIT License, and the independent online converter on this site is free to use with no account required to start. The free tier handles single files up to 20MB across every supported format with no artificial delay. A free account can save your 10 most recent Markdown results. If you need more, an optional Markitdown Pro plan raises the limit to 100MB per file and adds batch conversion of up to 30 files at once — see the Pricing page for details.

markitdown extracts text content from PDF files while preserving paragraph structure and formatting where possible. The PDF converter identifies headings, body text, lists, and tables to produce well-organized Markdown. Scanned image PDFs are supported too: the converter detects when a PDF has no selectable text and offers built-in AI OCR that reconstructs the content as Markdown — including tables and math equations converted to LaTeX. Free accounts include 10 OCR pages per month.

Yes, markitdown is designed to preserve document structure during conversion. Tables are converted to Markdown table syntax, headings maintain their hierarchy, lists keep their nesting, and inline formatting like bold and italic text is retained when the source format exposes that information clearly.

For local conversion, yes: the converter reads the file in your browser and never uploads it, and nothing is stored or transmitted while it runs. Two features are exceptions and you have to choose them — AI OCR sends rendered page images to our OCR provider over HTTPS; markitdown does not store OCR images or recognized text, and provider processing is governed by the provider's API data policy. From-URL mode fetches the page you name through a lightweight proxy. If you explicitly choose Save result, only the generated Markdown is sent to your private workspace so you can resume it across devices.

Markdown is a preferred input format for many AI systems, large language models, and knowledge management tools. By converting your files with markitdown, you make content easier to inspect, version, chunk, search, and reuse in RAG pipelines, AI assistants, documentation systems, and publishing platforms.

Absolutely — via Microsoft's MarkItDown, available as an open-source Python package that you can install and integrate into your own applications, scripts, and data pipelines. It works well in automated workflows, CI/CD pipelines, and batch processing systems.
