How to Convert Markdown to HTML
Markdown is the preferred format for developer documentation, GitHub READMEs, technical blogs, and note-taking applications. But when you need to publish content on the web, embed it in emails, or integrate it into a CMS, you need HTML. This free online Markdown to HTML converter transforms your Markdown into clean, semantic HTML instantly — entirely in your browser.
Why Convert Markdown to HTML?
Markdown is designed for writing, not rendering. To display Markdown content on websites, in email campaigns, or within applications, it must be converted to HTML. Static site generators handle this automatically, but there are many scenarios where you need the raw HTML — embedding content in CMS platforms that don't support Markdown, creating email newsletters from Markdown drafts, generating HTML documentation from README files, or previewing how Markdown will render before committing.
This converter supports the full CommonMark specification plus GitHub Flavored Markdown (GFM) extensions, so the HTML output matches what GitHub, GitLab, and other platforms render. It handles fenced code blocks with language identifiers, pipe tables with column alignment, strikethrough text, task lists, and autolinked URLs.
Common Use Cases
- Email newsletters: Write content in Markdown, then convert to HTML for email marketing platforms like Mailchimp, SendGrid, or ConvertKit.
- CMS integration: Convert Markdown blog posts and documentation into HTML for content management systems that require HTML input.
- Documentation sites: Generate HTML from Markdown source files for embedding in developer portals and API documentation.
- README preview: See how your GitHub README.md will render as HTML before pushing to a repository.
- Blog publishing: Convert Markdown drafts into HTML for WordPress, Medium, or custom publishing platforms.
- Presentations: Transform Markdown outlines into HTML slides for reveal.js or similar presentation frameworks.
Supported Markdown Syntax
This converter handles all standard Markdown syntax: headings (# through ######), paragraphs, bold (**text**), italic (*text*), inline code (`code`), fenced code blocks (```language), blockquotes (>), ordered and unordered lists, links ([text](url)), images (), horizontal rules (---), tables with alignment, strikethrough (~~text~~), task lists (- [ ] item), and nested combinations of all elements. The output is clean, semantic HTML using proper elements like h1-h6, p, strong, em, code, pre, ul, ol, table, and blockquote.
Privacy First
This Markdown to HTML converter runs entirely in your browser using the marked library. Your content never leaves your device — no API calls, no server processing, no data storage. This makes it safe for converting internal documentation, draft blog posts, and any Markdown content containing sensitive information.
