About PDF to Markdown

Turn any PDF into a well-structured Markdown document — headings, lists, and paragraphs are auto-detected. Perfect for importing into Obsidian, Notion, or your favorite note-taking app. Processed entirely in your browser.

Turning documents into a format writers and developers prefer

PDF is excellent for preserving layout, but it is essentially a display format — editing a PDF is awkward, searching across many PDFs is slow, and pasting PDF text into a writing tool often brings along broken formatting. Markdown solves all of those problems: it is plain text with lightweight syntax for headings, lists, and emphasis, which means it works in every text editor, renders beautifully in tools like Obsidian, Notion, and GitHub, and is easy to version-control alongside code.

This tool bridges the gap. You drop in a PDF and get back structured Markdown: headings detected from font sizes, paragraphs preserved, lists recognized. The output is clean enough to paste straight into a knowledge base, a blog editor, or a documentation repository without spending time reformatting by hand.

How the extraction works

The tool reads the PDF's text layer — the actual character data stored inside the file — and analyses each text run's font size, weight, and position. Runs significantly larger or bolder than the body text become Markdown headings at the appropriate level. Indented lines with bullet characters become list items. Paragraph breaks are inferred from vertical spacing. The result is a best-effort structural conversion, not a pixel-perfect layout clone.

Because it works from the text layer, the conversion is fast and fully private — there is no server involved. Multi-column layouts, decorative text boxes, and heavily designed pages may need light editing after conversion, but for reports, papers, manuals, and meeting notes the output is ready to use immediately.

Who benefits and practical tips

Researchers import papers into Obsidian to link ideas across notes. Developers convert API documentation PDFs into Markdown files they can commit to a repository. Students turn lecture slides into structured notes. Technical writers pull content out of legacy PDF manuals to migrate into modern documentation sites.

For the best results, start with PDFs that have a real text layer — digitally created documents, not scanned images. If you have a scanned PDF, run it through the OCR tool first to add a text layer, then convert to Markdown. And if your PDF contains tables, consider the PDF-to-CSV tool for those sections — Markdown tables are finicky, and a CSV is easier to work with in a spreadsheet before reformatting.

Questions

Everything runs in your browser. How we keep files private

How does it detect headings and structure?

The tool analyses font sizes and weights in the text layer. Larger or bolder text becomes a heading; indented or bulleted runs become list items. It is heuristic, so heavily styled or multi-column layouts may need a quick manual tidy.

Will it extract images too?

This tool focuses on text structure. For images, use the Extract Images tool first, then reference them in your Markdown. Combining both gives you a complete Markdown document with image files alongside it.

Does it work on scanned PDFs?

Only if the PDF already has a text layer (for example, from OCR). A pure scanned image with no embedded text will produce an empty or near-empty result. Run OCR first, then convert to Markdown.

Is my document uploaded anywhere?

No. The conversion runs entirely in your browser — text is extracted locally and the resulting Markdown never leaves your device.
