}

Markdown is easiest to proof when you can see the structure and the rendered result at the same time.

What This Tool Does

Markdown Previewer renders Markdown locally in your browser so you can inspect headings, lists, tables, code blocks, links, and inline HTML before publishing. This rewrite keeps editing and review close together, adds a live outline, and lets you export a standalone HTML copy for sharing or printing without sending drafts to a server.

When To Use It

Use it for README work, release notes, internal docs, runbooks, blog drafts, and any other Markdown that needs a quick presentation check. The sanitize toggle helps you compare a safer browser preview against raw HTML, while the clean and slate themes make it easier to review both clean and dark-surface reading contexts.

Workflow Tips

Edit in the source panel while the live preview tracks the rendered result, then use the outline to check rhythm, spacing, and heading hierarchy. Import existing .md files, load the sample document to test tables and fenced code blocks, and export HTML only after the outline and final headings look right.
