Features and use cases

Convert Markdown ↔ HTML with common GFM preview for publishing and CMS paste.

Use for README → web sections, HTML emails, static blog migration, and LLM → rich text.

Typical Workflow

When writing technical documentation, developers often draft content outlines in Markdown first. Pasting content into this tool instantly shows the converted HTML code and browser rendering. It's ideal for verifying formatting like heading hierarchies and table alignment, preventing rendering issues before committing to version control.

Content creators can convert long documents section by section. Start with chapter headings and lists, then progressively add complex elements like code blocks or nested tables. Live preview helps adjust line breaks and spacing—details that are hard to visualize in plain Markdown editors.

Examples

FAQ

Tables?

GFM table syntax works with marked.

Can I directly use the converted HTML on my website?

Basic formatting is ready to use, but you'll need to add CSS styles manually. The tool generates semantic HTML tags (like <code><section></code>) preserving Markdown's structure, but without visual styling. For complex projects, consider processing dynamic content with frontend frameworks.
