Markdown is a lightweight markup language created by John Gruber in 2004 that lets you write formatted content using plain text syntax. Instead of clicking toolbar buttons or writing verbose HTML tags, you use simple characters like # for headings, ** for bold, and - for list items. Its simplicity has made it the de facto standard for documentation on platforms like GitHub, GitLab, and Stack Overflow, as well as for README files, technical blogs, and note-taking applications.
Converting Markdown to HTML is necessary whenever you need to publish content on the web. Browsers render HTML, not Markdown, so any Markdown-authored content must be converted before it can appear on a web page, in an email newsletter, or inside a content management system. This tool performs that conversion instantly in your browser, producing clean semantic HTML that uses proper heading hierarchy, list structures, and code block formatting.
The converter supports standard Markdown syntax as well as common extensions like fenced code blocks, tables, and strikethrough text. Whether you are writing a blog post, building documentation, preparing an email newsletter, or simply previewing how your README will look, this tool gives you both a rendered preview and the raw HTML source with a single paste.
h1-h6 elements, paragraphs use p tags, lists use proper ul/ol/li structure, and code blocks are wrapped in pre and code elements. The output is ready to paste into any web page, email template, or CMS without additional cleanup.# for headings, ** for bold, and - for list items. Markdown is the standard for documentation on platforms like GitHub, GitLab, and Stack Overflow, and is widely used for README files, technical blogs, and note-taking applications.<strong> or <ul><li>, you use simple characters like ** for bold and - for list items. Markdown files are also readable as plain text, making them ideal for version control and collaboration. When you need the final output as HTML, a converter like this tool handles the transformation instantly.<div>, <span>, or <table> directly in your Markdown content, and most processors will pass them through to the final output. This is useful for adding custom attributes, complex layouts, or elements that Markdown does not natively support, such as video embeds or form elements.
