PDF to Markdown

This tool reverses the usual flow: it reads a text-based PDF and reconstructs clean Markdown from it, inferring headings from font sizes, detecting bullet and numbered lists, and grouping text into paragraphs. It is ideal for repurposing existing documents, moving content into a notes app or static site, or preparing PDFs as structured input for AI tools — all without uploading anything.

1. 1

   Drop a text-based PDF into the upload area.

2. 2

   PDF-Atlas extracts the text locally and infers structure — headings, lists and paragraphs.

3. 3

   Review and edit the generated Markdown directly in the output panel.

4. 4

   Copy it to your clipboard or download a .md file.

• Repurposing published documents

  Move the content of a PDF report or article into a CMS, wiki, or static-site generator that speaks Markdown.

• Feeding documents to AI

  Markdown is a clean, token-efficient format for large language models. Convert a PDF first, then paste the result into your assistant.

• Editing locked-down content

  Get editable text out of a PDF when you only have the finished document and not the source.

Does it work on scanned PDFs?

No — scanned PDFs are images with no selectable text, so there is nothing to extract. Run the OCR tool first to add a text layer, then convert to Markdown.

How accurate is the structure detection?

Headings and lists are inferred using heuristics (relative font size, line spacing, list markers), so results are a strong starting point rather than a perfect reproduction. The output is fully editable before you download it.

Is PDF to Markdown free to use?

Yes. PDF to Markdown is completely free, with no sign-up, watermarks, daily quotas, or file-size caps. You can process as many files as your device can handle.

Are my files uploaded to a server?

No. PDF to Markdown runs entirely in your browser using WebAssembly. Your documents never leave your device — there are no uploads, no servers, and nothing is stored or logged. That is what makes PDF-Atlas private by architecture.

Does PDF to Markdown work offline?

Yes. After the page has loaded once, the tool keeps working without an internet connection. You can also install PDF-Atlas as a desktop app or PWA for a fully offline experience.

Is my data safe?

Because all processing happens locally on your machine, your files are as safe as the device they sit on. Nothing is transmitted to PDF-Atlas or any third party.
