I Built a Free Markdown to HTML Converter (Because Dillinger Stores Your Content on Their Servers)

Description and use

A simple client‑side Markdown to HTML converter that runs entirely in the browser, never uploads data, and offers instant preview and download.

Problem

Using Dillinger.io to convert Markdown to HTML exposes user content to the provider’s servers, compromising privacy for sensitive documentation.

Outcome

The tool delivers instant, privacy‑preserving Markdown to HTML conversion with no server round‑trips, no data collection, and no vendor lock‑in.

Workflow

• Open the web app in a browser
• Write or paste Markdown into the left pane
• View the rendered HTML instantly in the right pane
• Click the download button to save the generated HTML file
• (Optional) Remove the watermark comment from the HTML

Evidence

The converter is entirely client‑side JavaScript. There's no server, no database, no analytics.
