The tool builds on MarkItDown, Microsoft's open-source document-to-Markdown converter for LLM and text-analysis workflows, and preserves headings, lists, tables, and links for reuse in ChatGPT, Claude, Obsidian, Notion, and RAG pipelines. A separate Advanced option for eligible scanned or complex documents requires sign-in and discloses its upload and retention boundary before processing.", "body_md": "### What is MarkItDown?\n\nMarkItDown is an open-source document-to-Markdown converter from Microsoft for LLM and text-analysis workflows.\n\nUse MarkItDown Online to convert PDF, DOCX, PPTX, XLSX, HTML, CSV, JSON, and XML into clean Markdown.Browser Basic runs locally in your browser; Advanced is for eligible scanned or complex files.\n\nMarkItDown Online is a browser-based document-to-Markdown converter for supported local files. It preserves useful structure such as headings, lists, tables, links, and readable text so the result is easier to review, edit, search, and reuse in ChatGPT, Claude, Obsidian, Notion, and RAG workflows. It is an independent tool and does not provide persistent file hosting, public sharing, or remote downloads.\n\nChoose a supported local file, preview the Markdown, then copy or download the result without installing Python or uploading the source.\n\nMarkdown keeps headings, lists, tables, and links easier to reuse in ChatGPT, Claude, Obsidian, Notion, and RAG systems.\n\nMarkItDown AI is independent conversion software, not a file-hosting, file-sharing, cyberlocker, or remote-download service.\n\nUse the web flow when you want one quick Markdown file instead of setting up command-line tools.\n\nInstall the original Python package when you need automation, scripting, or controlled processing on your own machine.\n\nUse the browser converter for a quick, supported file that you want to preview and download. Install the original Python package when you need scripts, automation, batch workflows, or format support that this page does not promise.\n\n| Features | Online Converter | Python Install | \n|---|---|---|\n| Best for | Quick document-to-Markdown conversion | Developer workflows and automation | \n| Setup | Open the page and choose a file | Install Python package and dependencies | \n| Input | PDF, DOCX, PPTX, XLSX, HTML, CSV, JSON, XML | Depends on your local package setup | \n| Output | Preview, copy, or download Markdown | Markdown output for scripts and pipelines | \n| Skill level | No command line required | Comfortable with terminal commands | \n| Use case | AI notes, docs, knowledge bases | Batch jobs, local files, custom tooling | \n\nThe open-source project can support more formats depending on setup. This online page only promises the formats listed in the local file area.\n\nChoose a PDF, Word, PowerPoint, Excel, HTML, CSV, JSON, or XML file, or drop it into the local file area.\n\nWait while the file is converted into Markdown that is easier to inspect, edit, search, and reuse.\n\nPreview the Markdown output, copy it into your workflow, or download it as a .md file.\n\nConversion focuses on useful document structure rather than pixel-perfect layout. When the source file contains readable text, the result can preserve headings, paragraphs, lists, tables, and links in plain Markdown that is easier to inspect and edit.\n\nSection headings create a clear outline for notes, prompts, and RAG chunks. Review the preview when a source uses columns, text boxes, or an unusual reading order.\n\nBullets, numbered steps, simple tables, and hyperlinks remain easier to reuse than text copied directly from many PDFs or Office files.\n\nInspect and edit the Markdown, copy it into an AI tool, or download a .md file before adding it to documentation or a knowledge base.\n\nBrowser Basic is the default for supported, text-based files and processes them locally in the browser. It does not upload the source file. Advanced is a separate option for eligible scanned or complex documents; it requires sign-in, explains its upload and retention boundary before processing, and may not be available for every account.\n\nThe original MarkItDown package is designed for developers who want local commands, Python APIs, or controlled automation. For one supported file, the browser converter removes setup; for repeatable or custom workflows, use the package in your own environment.\n\nBest when you just need a quick Markdown file from a supported document.\n\nBest for developers who want the original MarkItDown package in a local or scripted workflow.\n\nUse online conversion for speed, and use the Python package when you need automation or deeper control.\n\nConvert PDF files into Markdown for AI workflows.\n\nConvert DOCX documents into clean Markdown.\n\nConvert slides into Markdown notes and summaries.\n\nConvert spreadsheets into Markdown tables.\n\nUse the homepage converter for supported CSV files.\n\nUse the homepage converter for supported HTML files.\n\nChoose a supported file, preview the Markdown, then copy or download the result.", "url": "https://wpnews.pro/news/show-hn-markitdown-ai-convert-documents-to-markdown-locally-in-the-browser", "canonical_source": "https://markitdownai.org", "published_at": "2026-10-20 12:29:11+00:00", "updated_at": "2026-10-20 12:46:42.817471+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools", "large-language-models", "ai-products"], "entities": ["MarkItDown", "MarkItDown Online", "Microsoft", "ChatGPT", "Claude", "Obsidian", "Notion"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-markitdown-ai-convert-documents-to-markdown-locally-in-the-browser", "markdown": "https://wpnews.pro/news/show-hn-markitdown-ai-convert-documents-to-markdown-locally-in-the-browser.md", "text": "https://wpnews.pro/news/show-hn-markitdown-ai-convert-documents-to-markdown-locally-in-the-browser.txt", "jsonld": "https://wpnews.pro/news/show-hn-markitdown-ai-convert-documents-to-markdown-locally-in-the-browser.jsonld"}}
