Markdown to HTML Converter

HTML output 
 
 
How to Use
 
 
Paste or type Markdown into the input area. The converted HTML appears below in real time, pretty-printed by default. Toggle the Minified checkbox to collapse whitespace for production use, then press Copy to grab the result. All GitHub-Flavored Markdown features — headings, emphasis, lists, tables, blockquotes, code blocks, and links — are supported.
 
What Is Markdown
 
 
Markdown is a plain-text formatting syntax invented by John Gruber in 2004. It lets you write structured documents using simple characters like # for headings, * for emphasis, and - for lists. It is widely used in README files, documentation sites, static blogs, chat apps, and content management systems. GitHub-Flavored Markdown (GFM) extends the original with tables, task lists, strikethrough, and fenced code blocks with syntax highlighting.
 
Output Formats
 
 
This tool offers two output formats: pretty-printed HTML with 2-space indentation (readable, copy into files), and minified HTML with inter-tag whitespace removed (smaller file size, production-ready). The converter uses the `marked` parser with GFM mode enabled, and the output is sanitized with DOMPurify to prevent injection issues when you paste the result into live pages.
 
Common Use Cases
 
 
  • Bloggers converting draft posts written in Markdown into HTML for CMS systems that do not accept Markdown directly.
  • Technical writers turning documentation into HTML for publication on static sites or intranet wikis.
  • Developers generating HTML snippets for email templates, help tooltips, or CMS body fields.
  • Students and content creators producing clean HTML for school projects, portfolios, or blog migrations.
  • Quickly verifying how a Markdown snippet will render in HTML before committing it to a repository.
 
Tips
 
 
  • GFM tables require a header row and a separator line with pipes and dashes.
  • Fenced code blocks support a language identifier (```js, ```python) — the identifier is emitted as a CSS class.
  • Minified output is best for production (smaller payload); pretty output is easier to read and hand-edit.
  • Inline HTML inside Markdown is passed through but sanitized, so unsafe tags like <script> are removed.
  • Raw URLs are auto-linked when GFM mode is on (e.g. https://example.com becomes a clickable link).
 
Privacy
 
 
All Markdown parsing happens in your browser. Your document is never sent to any server or stored anywhere.
 
FAQ
 
 
What's the difference between pretty-printed and minified output?
 
Pretty-printed HTML uses 2-space indentation that's easy to read and hand-edit. Minified output strips whitespace between tags for a smaller payload suited to production. Toggle the Minified checkbox to switch.
Does it support GitHub-Flavored Markdown features like tables?
 
Yes. The converter runs the `marked` parser with GFM mode on, so tables, task lists, strikethrough, fenced code blocks, and autolinked raw URLs are all supported.
Is the generated HTML safe to paste into a live page?
 
Yes. Output is sanitized with DOMPurify, so unsafe tags such as <script> are removed. Inline HTML you include in the Markdown is passed through but goes through the same sanitizer.
Is it safe to convert private or unpublished documents?
 
Yes. All parsing happens in your browser — your document is never uploaded, logged, or stored — so confidential drafts stay on your device.
How do I get a language class on a code block?
 
Add a language identifier after the opening fence (```js or ```python). The identifier is emitted as a CSS class on the generated code element, which highlighters can target.
