Convert Markdown to HTML in your browser
Markdown gives you a fast way to write structured content without touching HTML tags. This converter renders a live preview as you type and exposes the underlying HTML when you need it. Use it to draft blog posts, build email layouts, prepare documentation, or translate README files into web-ready markup. Everything runs in your browser using the CommonMark-compliant marked parser, so there is no sign-up, no upload, and no waiting on a server round trip.
How to use this tool
Paste or type Markdown into the editor on the left. The Preview pane on the right updates instantly so you can verify formatting decisions like heading hierarchy, list indentation, and code blocks. Switch to the HTML source view to inspect the generated markup, then copy it to your clipboard or download it as a standalone .html file. Click Load sample to populate the editor with a Markdown reference you can edit and learn from.
CommonMark and GitHub flavor
The parser supports the full CommonMark specification — headings with #, emphasis with * or _, ordered and unordered lists, links and images, fenced code blocks, and blockquotes. GitHub Flavored Markdown extras include tables with pipe syntax, strikethrough with ~~, and task lists using - [ ] and - [x].
Common use cases
Documentation: turn README drafts into the HTML your docs site expects. Email: generate rich-text email bodies without hand-writing tags. CMS migration:convert legacy Markdown content into HTML for platforms that don't support Markdown natively. Static sites: preview how a post will render before committing.
Questions
Frequently asked questions
What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It lets you format text using simple punctuation — like # for headings, * for emphasis, and - for lists — and then convert it to HTML or other formats. It's widely used for READMEs, documentation, blog posts, and chat messages on GitHub, Reddit, Discord, and Slack.
Which Markdown syntax does this tool support?
This tool follows CommonMark with GitHub Flavored Markdown extensions, so it understands headings, bold and italic, ordered and unordered lists, links, images, fenced code blocks with language hints, blockquotes, horizontal rules, tables, strikethrough, and task lists with checkboxes.
What is the difference between the Preview and HTML source views?
Preview shows your Markdown rendered as a styled web page, exactly how a reader would see it. HTML source shows the generated HTML markup as text — useful when you want to copy the HTML into a CMS, email template, or static site generator.
Is my Markdown sent to a server?
No. All parsing and rendering happens locally in your browser using the open-source marked library. Your text never leaves your device, and the tool works offline once the page has loaded.
Can I export the HTML as a file?
Yes. Click Download .html to save the generated HTML as a standalone file you can open in any browser, attach to an email, or include in a project. The Copy HTML button puts the same content on your clipboard for quick pasting.
