What is Markdown to HTML conversion?

Markdown to HTML conversion transforms plain-text Markdown syntax into equivalent HTML markup. Markdown is easy to read and write as plain text, while HTML is what browsers use to render web content. This tool parses your Markdown and generates clean, semantic HTML you can use directly in web pages, email templates, or any HTML-based system.

What Markdown elements does this converter support?

This converter supports ATX-style headings (H1–H4), bold (**text**), italic (*text*), bold+italic (***text***), strikethrough (~~text~~), inline code, fenced code blocks with language hints, links, images, unordered lists, ordered lists, blockquotes, horizontal rules, and paragraph separation.

Does the generated HTML include any CSS classes or styles?

No. The converter outputs plain semantic HTML using standard tags ( , , , , , , , , , , ) with no inline styles or CSS classes. This makes the output framework-agnostic so you can style it with any CSS.

What is the difference between the HTML Code and Preview tabs?

The HTML Code tab shows the raw HTML markup generated from your Markdown — this is what you copy and paste into your project. The Preview tab renders that HTML directly in the browser so you can see the visual result. Use both tabs to verify correctness and appearance.

Can I use this tool to convert Markdown for websites and emails?

Yes. The generated HTML is clean and standards-compliant, suitable for web pages, CMSs, email newsletters, and documentation. For email use, you may need to add inline styles afterward since most email clients have limited CSS support.
