100% client-side. Your file never leaves your browser.
Your PDF is processed entirely in your browser. Nothing is uploaded to any server.
Headings, bold text, and lists are detected automatically using font-size heuristics.
Runs on any modern browser — desktop, tablet, or mobile. No software to install.
PDF is a layout format: it describes where characters sit on a page, not what the document means. That is perfect for printing and terrible for machines. Markdown is the opposite — a lightweight text format that keeps the structure (headings, lists, emphasis) and drops the layout noise.
This matters most for AI workflows. Large language models are trained on enormous amounts of Markdown, so they parse it natively: a # heading tells the model exactly where a section starts, which makes chunking for RAG pipelines accurate instead of arbitrary. Markdown is also token-efficient — the same content costs significantly fewer tokens than HTML or a JSON layout dump, which directly reduces your LLM bill.
Typical uses: feeding reports and documentation into Claude or ChatGPT, building knowledge bases for AI agents, populating vector databases for retrieval-augmented generation, migrating PDF documentation to a wiki or static site, or simply getting readable text out of a locked document.
Drag and drop or click to select a PDF file from your device. It is read locally — never uploaded.
The engine reads every page, measures font sizes to find headings, and converts the content to structured Markdown.
Copy the Markdown to your clipboard or download it as a .md file, ready for your editor, wiki, or LLM prompt.
An honest note: browser-based conversion is great for most digital documents, but it is not magic. Here is what to expect.
No. The entire conversion happens in your browser using JavaScript (PDF.js). Your file never leaves your device, which makes this tool safe for contracts, invoices, medical records, or any confidential document.
Markdown preserves document structure — headings, lists, emphasis — using lightweight syntax that language models understand natively. Compared to raw PDF text, Markdown gives the model section boundaries for accurate chunking, and it uses far fewer tokens than HTML or JSON representations of the same content.
The tool analyzes font sizes across your PDF. Text significantly larger than the body font is converted to Markdown headings (H1, H2, H3), and bold text is wrapped in **bold** markers. This heuristic works well for reports, documentation, and articles with a consistent visual hierarchy.
This tool works with digital PDFs that have an embedded text layer. Scanned PDFs are images, so they require OCR — that is available through the ParseDocu API, which handles both digital and scanned documents.
Simple tables come through as plain text lines. Reliable table reconstruction (rows, columns, headers) requires layout analysis that goes beyond what a browser tool can do — the ParseDocu API includes a dedicated table extraction endpoint for that.
No hard limit. Because everything runs locally, speed depends on your device — most PDFs under 50 MB convert in a few seconds.
Yes, completely free and unlimited, with no account or email required. It is our way of showing what ParseDocu does before you try the API.
For batch or automated conversion, use the ParseDocu API: one POST request returns clean Markdown with consistent quality, and it plugs into Zapier, Make, and n8n for no-code workflows. The free tier includes 1,000 credits.
This tool is perfect for one-off conversions. When you need OCR, structured tables, or automation, the PDF to Markdown API takes over.
