About this tool
Paste any Markdown - headings, lists, code, tables, blockquotes, task lists - and see the rendered HTML and a live preview side-by-side. Supports GitHub-Flavoured Markdown (tables, strikethrough, task lists, autolinks) via remark + remark-gfm. Output is plain HTML, safe to drop into a CMS or templating engine.
FAQs
Which Markdown flavour does this support?
GitHub-Flavoured Markdown (GFM). That includes CommonMark plus tables, strikethrough, task list checkboxes, autolinks, and fenced code blocks with language hints.
Is the output sanitised?
Raw HTML inside Markdown is preserved (so you can write <kbd>Ctrl</kbd> or <sub>2</sub>). Strip it server-side before storing if you're rendering untrusted user content - the tool itself doesn't escape arbitrary HTML.
Does it syntax-highlight code blocks?
Code blocks are wrapped in <pre><code class="language-…"> with the language class. Pair the output with Prism, Shiki, or highlight.js on your site to colourise.
Are footnotes supported?
Yes via remark-gfm - use [^1] in the text and [^1]: explanation at the bottom. Definition lists are not part of GFM; for those you'd need remark-deflist or pandoc.
Does anything I paste leave my browser?
No. Markdown parsing runs entirely in your browser via the remark JavaScript library. Nothing is uploaded or logged.
