About PDF to Markdown.

Convert a PDF to Markdown — In Your Browser

Drop a PDF and get clean GitHub-flavored Markdown: headings, paragraphs, and bullet or numbered lists, with a “---” rule between pages. CipherForces PDF to Markdown reads the document's real text layer with PDF.js — the same engine Firefox uses — reconstructs each line from the positioned characters, measures font sizes to work out which lines are headings, and writes it all out as tidy Markdown you can copy or download as a .md file. The free tier covers 5 conversions per day.

Markdown is the format large language models read best, so this is the fast way to turn a report, spec, or manual into something you can paste into ChatGPT or Claude, drop into a RAG pipeline, or commit to a repo. Everything runs on your device — nothing is uploaded — so it is safe for contracts, financials, and anything confidential. Toggle heading detection, paragraph reflow, and page separators on or off, and flip to a live rendered preview to check the result before you export.

Honest about the limits: this needs a digital PDF with a selectable text layer — a scan or image-only PDF has no text to convert, and the tool says so instead of handing back a blank file (run OCR first). Structure is best-effort: font-size heading detection is a heuristic, and multi-column pages and tables are read in top-to-bottom order, so complex layouts may need a quick manual tidy.

Common Use Cases

  • Feed an LLM or RAG index: Convert a PDF into the clean Markdown that ChatGPT, Claude, and embedding pipelines parse most accurately.
  • Move docs into a repo or wiki: Turn a spec, whitepaper, or manual into a .md file ready for GitHub, GitLab, Obsidian, or Notion.
  • Reuse report content: Pull the headings and body of a long report into Markdown you can restructure instead of retyping it.
  • Draft from a PDF source: Get a heading outline and paragraphs to start a blog post, summary, or set of notes.
  • Convert a protected PDF you own: Enter the password locally to unlock an encrypted file — the password never leaves your browser.

Privacy: All parsing and Markdown generation happen entirely in your browser with client-side JavaScript. Your PDF is never uploaded, and there is nothing to sign up for.
