PDF to Markdown Converter — Free, Private, In-Browser

PDF to Markdown — Free & 100% Private

Convert a PDF into clean Markdown (.md) — ideal for feeding documents into AI tools and LLMs, taking notes, or publishing to the web. AccuPDF extracts the text, detects headings automatically, and builds Markdown entirely in your browser, so your document is never uploaded.

How to convert PDF to Markdown

  1. Drop your PDF into the tool.
  2. Click Convert to Markdown.
  3. Preview the Markdown on screen — the .md file downloads automatically.

Why convert PDF to Markdown?

Markdown is the native format for AI assistants, documentation sites, static blogs and note apps like Obsidian. Turning a PDF into Markdown makes its content easy to edit, search, version-control and paste into an LLM prompt without the noise of a binary PDF.

How the conversion works

AccuPDF reads the PDF’s text layer with pdf.js, groups it into lines, and infers headings from relative font sizes. It works best on text-based PDFs; scanned image-only PDFs should first be run through OCR. Everything is processed on your device — no uploads.
