Why Your Markdown Never Leaves Your Browser

We built MarkdownTools with privacy as a core principle. Here's how it works under the hood.

Privacy isn't a feature we added — it's how the entire tool is architected.

HTML Export: 100% Client-Side

When you export as HTML, everything happens in your browser. The markdown is parsed, the theme CSS is bundled, and the HTML file is generated — all locally. No server request. No upload. Nothing leaves your device.

PDF Export: Stateless Server

PDF generation requires a server (headless Chromium can't run in a browser). But our API is completely stateless:

  • Your content is sent to the server
  • The PDF is generated in memory
  • The PDF is returned to your browser
  • Nothing is logged, cached, or stored
The server has no database, no file storage, no session state. It processes your request and forgets it existed.

No Tracking

No analytics. No cookies. No tracking pixels. We don't know who you are, what you're converting, or how often you use the tool.

Why This Matters

If you're converting confidential reports, internal documentation, or sensitive AI output — your content stays private. That's not a marketing claim. It's an architectural guarantee.
