About this tool
Write Markdown, get clean HTML
Markdown is a simple way to write formatted text using plain characters, and it is what powers README files, documentation, forum posts and many note apps. But the web needs HTML. This Markdown to HTML converter bridges the two: type Markdown on the left and watch the formatted result render on the right in real time, then grab the HTML when you are happy with it.
It supports the formatting you actually use: headings, bold and italic, strikethrough, inline code and fenced code blocks, links, images, blockquotes, ordered and unordered lists, task lists with checkboxes, horizontal rules and tables. Toggle the output between a rendered preview and the raw HTML source so you can either check how it looks or copy the markup directly into your site, CMS or email.
Everything happens in your browser. The converter is plain JavaScript with no external library, so your text is never uploaded, and your draft is saved locally in case you reload. It is fast, free and works without an account, which makes it handy for turning notes into a web page, prepping documentation, or learning how Markdown maps onto HTML.

FAQ
Frequently asked questions
How do I convert Markdown to HTML?
Type or paste Markdown into the left pane and the rendered HTML appears in the right pane as you type. Switch the right pane to Source to see the raw HTML, then click Copy HTML or Download to save it as an .html file. There is no button to press and nothing to configure, the preview updates on every keystroke.
What Markdown features are supported?
Headings (# to ######), bold, italic and strikethrough, inline code and fenced code blocks, links and images, blockquotes, ordered and unordered lists, task lists with checkboxes, horizontal rules and tables. It covers the common GitHub-flavoured Markdown you write day to day.
Is my text sent to a server?
No. The converter is written in plain JavaScript and runs entirely in your browser, so your Markdown never leaves your device. Raw HTML written inside the Markdown is escaped rather than executed, which keeps the preview safe without needing any third-party sanitiser library.
Can I copy just the HTML output?
Yes. Switch the preview to Source view to see the generated HTML, then use the Copy HTML button to put it on your clipboard, or Download to save it as a complete .html file you can open in any browser or paste into a CMS, email template or static site.
Does my work get saved if I reload?
Yes. Your Markdown is remembered in your browser's local storage, so if you accidentally close or reload the tab, your text is restored. It is stored only on your own device and is never uploaded.
