FAQ
MarkItDown AI is an independent online tool that converts documents like PDF, Word, PowerPoint, Excel, HTML, CSV, and JSON files into clean, structured Markdown format, optimized for AI workflows and note-taking.
No. This is an independent online converter experience. The original MarkItDown is an open-source project from Microsoft, but this site provides a separate, web-based interface for easier access.
You can convert PDF, DOCX (Word), PPTX (PowerPoint), XLSX (Excel), HTML, CSV, and JSON files. The online tool is limited to these formats for reliable conversion.
No. MarkItDown Online cannot perform OCR (Optical Character Recognition) and therefore cannot convert scanned PDFs or image-based documents into text Markdown.
The Markdown output is ideal for AI workflows (like feeding into ChatGPT or Claude), creating notes in Obsidian or Notion, building searchable knowledge bases, or for any text-analysis and RAG (Retrieval-Augmented Generation) systems.
No. MarkItDown Online runs entirely in your web browser. You only need to install the original Python package if you require automation, scripting, or local batch processing.
The website does not specify a file size limit, but performance may depend on your browser and internet connection. Very large files might take longer to process or could encounter timeouts.
After conversion, a preview of the Markdown is shown. You can copy the text directly or use a download button (if provided on the conversion result page) to save it as a .md file.
According to the site's Privacy Policy, uploaded files are processed temporarily for conversion and are not stored long-term. However, for highly sensitive documents, using the local Python package is recommended.
No. MarkItDown Online is designed for single-file, on-demand conversion. For batch processing, you should install the original MarkItDown Python package on your local machine.
