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

Description and use

A browser‑based Markdown to HTML converter that keeps all data local, offers instant preview, and allows one‑click download without any server interaction.

Problem

Users need to convert Markdown to HTML without their content being stored on third‑party servers, as with Dillinger.io.

Outcome

The converter delivers instant, privacy‑preserving Markdown to HTML conversion entirely within the browser, eliminating the need for server uploads, accounts, or data collection.

Workflow

• Open the converter URL 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 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.
