How to use
01
Write or paste Markdown
The left pane starts with a small sample document. Replace it with your own content; conversion happens automatically as you type, with no button to press.
02
Check the Preview tab
The right pane renders your document so you can confirm headings, emphasis, links, and code blocks look right before taking the markup.
03
Switch to HTML and copy
Click the HTML tab to see the generated tags, then use Copy HTML to grab the full output for your template or CMS.
Why Markdown to HTML
- Uses the actively maintained marked.js library.
- Side-by-side Markdown source and rendered preview.
- 100% client-side.
Common questions
What flavor of Markdown does the converter understand?
marked.js with GitHub Flavored Markdown enabled, so beyond the basics you get fenced code blocks, tables, and autolinked URLs. If it renders in a GitHub README, it will almost always convert the same way here.
Why is there no Convert button on the Markdown page?
Because the conversion is live. Every keystroke re-parses the document and updates both tabs, which turns the page into a scratchpad: adjust the Markdown, watch the output shift, repeat. To convert markdown to html online you just paste and read the result.
Will the raw HTML tags in my Markdown be escaped?
No, inline HTML passes through unchanged, which is standard Markdown behavior. That's convenient for embedding a video tag, and it's also why you should sanitize the output server-side whenever the Markdown comes from users rather than from your own files.
Does anything get uploaded while I type Markdown?
No. This markdown converter online parses everything client-side, so drafts, internal docs, and unreleased release notes never leave the tab. Close the page and the content is gone.
How does a fenced code block convert to HTML?
Three backticks with a language hint become a pre element wrapping a code element, with the language recorded as a class such as language-js. Your site's highlighter can pick that class up; the converter itself doesn't inject any colors.
Where does the HTML from this converter work best?
Anywhere that accepts raw markup: a CMS HTML block, a template partial, an email builder's code view. The output is plain semantic HTML with no wrapper div and no inline styles, so it inherits whatever styles the destination already has.
