How the Markdown Previewer Works
The Markdown previewer converts Markdown syntax into formatted HTML directly inside your browser. When you type headings, lists, bold text, links, or code blocks, the tool renders the final appearance instantly without sending data to a server.
This makes it useful for preparing README files, documentation pages, and notes before publishing them to platforms that support Markdown formatting such as repositories, blogs, and documentation systems.
Because everything runs locally, your text is never uploaded or stored. You can safely write drafts, technical documentation, or private notes and view the final layout exactly as readers will see it.

Preview technical documentation accurately.
Local Rendering
