PDF to Markdown

Turn any PDF into editable Markdown — headings, lists, code blocks and paragraphs rebuilt from the page geometry. The return trip of our Markdown to PDF converter, done entirely in your browser.

OR DRAG & DROP HERE — MULTIPLE FILES AT ONCE

EXTRACTION OPTIONS
Drop one or more PDFs to get clean Markdown with headings, lists and code blocks. Everything runs locally — no upload, no account, no watermark.

Everything runs in your browser — your PDF never leaves your device.

Why the reverse trip is harder

Markdown carries meaning: this line is a heading, that one is a list item, this block is code. A PDF carries only glyphs with coordinates — instructions like “draw this 11pt Helvetica at x=56, y=712”. There is no paragraph, no heading, no bullet list inside the file. That is why converting PDF to Markdown is a reconstruction job, not a lookup: this tool measures the geometry and rebuilds the structure it can prove, then tells you honestly what it could not.

  • Lines first: text fragments sharing a baseline are grouped into visual lines and ordered left to right, with spaces inferred from the gaps between fragments.
  • Body size is measured, not assumed: the dominant font size is computed by character weight, so headings are detected as those lines that are visibly larger than the running text.
  • Structure follows: bullet glyphs and numbered leads become real lists, monospace runs become fenced code, and short bold lines are treated as subheadings.

What makes the output editable

  • Paragraphs are glued back together: PDFs break a sentence at every line, so wrapped lines are rejoined — including words split across lines with a hyphen (docu- ment becomes document).
  • Code keeps its indentation: monospace lines are rebuilt on a character grid, so indentation and alignment survive instead of collapsing to a single space.
  • Running heads and page numbers disappear: text repeated on every page (and standalone page numbers) is detected and dropped, so the document reads as one continuous text.
  • Lists keep their numbering: an ordered list stays ordered with the numbers printed in the PDF, not a renumbered guess.
  • Optional YAML front matter: switch it on to prepend title, source file name, page count and extraction date — handy for static site generators and knowledge bases.

Who needs PDF to Markdown

Markdown is the format that AI systems, documentations and note apps read best. Typical uses: migrating old reports into a docs repository, turning research papers into notes for Obsidian or Notion, preparing source material for RAG pipelines and LLM prompts, editing a contract or a syllabus you can only get as a PDF, and keeping version history of documents that arrive as email attachments.

Going the other way? Our Markdown to PDF converter typesets Markdown into a clean A4 PDF with selectable text.

The honest limitations

  • Scanned PDFs have no text to extract. If the file is a photo of a page, you need OCR — real OCR engines need a server or a desktop app, and we will not pretend the browser can do it well. The tool tells you when this happens.
  • Tables come out as lines of text, not Markdown tables. Cell content is preserved; the grid is not rebuilt.
  • Multi-column layouts can interleave. Reading order is inferred from geometry, so columns may need a light cleanup — turn off “join wrapped lines” for those documents.
  • Images, links and form fields are not exported. This is a text-to-text converter, not a layout converter.
  • Headings are a heuristic. Fonts without size contrast (or bold that is not detectable in the file) mean some headings arrive as plain paragraphs — the toggles exist so you can tune the result per document.
  • Encrypted PDFs must be unlocked first — use our PDF Unlock tool, then convert.

Your privacy

Extraction runs entirely in your browser using the pdf.js engine. Your PDF is never uploaded, never stored and never logged — contracts, medical reports and internal documents stay on your device. Once the page is loaded, the conversion even works offline.

Frequently Asked Questions

How do I convert a PDF to Markdown for free?+

Choose one or more PDFs, pick your extraction options, click Extract Markdown, then download the .md file (or all files as a ZIP). No sign-up, no watermark, no page limit — everything happens in your browser.

Why did my PDF come out as plain text without headings or lists?+

That usually means the font sizes are uniform, or the file has no real text layer. If every line is the same size, there is nothing for the tool to measure, so it returns faithful plain text instead of inventing structure. Scanned PDFs need OCR before they reach this tool.

Are tables converted into Markdown tables?+

No, and we prefer to say it clearly. Cell content is extracted, but it arrives as lines of text with the columns separated by spaces. Rebuilding a reliable table grid from PDF geometry is possible only with heavy guessing, which would silently corrupt data. A text export you can clean up is more honest than a table that lies.

Can it read scanned or image-only PDFs?+

No. Those files contain pictures of text, not text. Optical character recognition (OCR) requires models far too large to run reliably inside a browser tab, so this tool detects the situation and tells you instead of producing empty output. Run an OCR step elsewhere, then bring the resulting PDF here.

Is the output good enough for AI, RAG or documentation pipelines?+

For digital-born PDFs (Word, Google Docs, LaTeX, InDesign exports) the result is clean, deterministic Markdown with headings kept as structure, which is exactly what retrieval pipelines want. YAML front matter can carry the source file name and page count. Review the first page or two before bulk-processing hundreds of files.

Is my PDF uploaded to your servers?+

Never. The pdf.js engine runs in your browser and the extraction code reads the file locally. Nothing is transmitted, stored or logged, which is why the tool also works offline after the page loads.
