About Markdown to PDF

Markdown to PDF is a free conversion tool that runs entirely in your browser. Paste Markdown, preview the result, and export to PDF, Word, or HTML — no signup, no payment, no uploading content to any server.

Why this tool exists

Over the last couple of years, more and more people have been pasting output from ChatGPT, Claude, and Gemini into real work documents. The problem: these AI tools speak Markdown by default. Copy that output into Word or an email and the formatting falls apart instantly — headings become # signs, lists become - dashes, code blocks lose their monospace font.

Most existing Markdown converters have one of three problems: they force you to sign up and pay; they impose page or word limits; or they upload your content to a server to process it — which is a non-starter for the many AI conversations that contain unreleased work.

So this site sets out to do one simple thing: make Markdown conversion fully client-side in the browser. Free to use. Browser-limited. Never uploaded.

How it works

Conversion happens on your device, not on our server. Specifically:

• PDF export uses the browser's native print engine (the same one behind Save as PDF) inside a hidden iframe, so the final layout is governed by your browser's print settings.
• Word export uses the open-source docx package to assemble a .docx binary in the browser, with font tuning that handles mixed Latin and CJK text cleanly.
• HTML export uses a unified + remark + rehype-sanitize pipeline to render locally, then sanitizes and copies the result to your clipboard.

In every case, your Markdown never leaves your browser. There is no upload-convert-download round trip — because there is no server-side converter to upload to.

Built with

This site stands on the following open-source stack:

• Next.js (app framework) + React (UI) + TypeScript (type safety)
• Tailwind CSS (styling) + CodeMirror 6 (editor)
• unified / remark / rehype (Markdown parsing and rendering)
• docx (Word document generation)
• Supabase (optional account system, used only to store conversion-history metadata)
• Vercel (frontend hosting)

Our principles

• Free — no charge, no signup, no server-side quota; the only practical limit is what your browser can hold in memory.
• Privacy first — no first-party analytics (no Google Analytics, no Plausible), no reading your Markdown.
• Transparent — every third-party dependency is listed explicitly in the Privacy Policy.
• Sustainable — intended to be supported by Google AdSense advertising rather than subscriptions; as long as ad revenue covers the running costs, the tool stays free.
