About this tool

The Markdown to HTML Converter turns Markdown text into clean, semantic HTML directly in your browser. Paste or type your Markdown into the input panel and the result appears immediately, with no button to press and no page reload. It handles the Markdown most people write every day: headings, bold and italic text, links, images, ordered and unordered lists, blockquotes, fenced code blocks and tables.

The output panel has two views. Rendered Preview shows how the content will look once it is on a web page, which is useful for catching broken lists or missing blank lines before you publish. HTML Source shows the raw markup so you can see exactly which tags were generated. When you are happy with the result, the Copy button puts the HTML on your clipboard, ready to paste into a CMS, a website template or an email builder. Load Sample fills the editor with an example, and Clear resets everything.

A live counter under the editor tracks words, characters, lines and HTML elements as you work. That is handy for checking the length of a draft, or for seeing how many elements your Markdown expands into. If your Markdown includes JSON snippets, run them through the JSON Formatter & Validator before publishing. When you need placeholder paragraphs to preview a page template before the real copy is ready, generate them with the Lorem Ipsum Generator and convert them here.

The converter runs entirely client-side. Your text is processed in your browser and is never uploaded or stored on a server, so you can safely convert drafts, internal documentation or unpublished articles. As with any tool that produces HTML, review the output before publishing content that came from someone else, and sanitize it if it will be shown to other users.

Frequently asked questions

How to convert Markdown to HTML?
Paste your Markdown into the input panel. The tool converts it as you type. Open the HTML Source tab to see the code, then click Copy and paste it into your website, CMS or email tool. Nothing is uploaded; the conversion runs in your browser.
How to convert HTML to Markdown?
This tool converts in one direction only, Markdown to HTML. To go from HTML to Markdown you need a dedicated HTML to Markdown converter, which reverses the process by turning tags like <strong> and <a> back into Markdown syntax.
How to save Markdown as HTML?
Convert your Markdown here, open the HTML Source tab and click Copy. Paste the code into a plain text editor such as Notepad or VS Code and save the file with an .html extension. Wrap it in a basic <html><body> page if you want it to open as a full web page.
How to render Markdown in HTML?
Browsers can't render Markdown directly, so it has to be converted to HTML first. Paste your Markdown here to get the HTML, then place that HTML inside your page. You can also use a Markdown library such as marked or markdown-it in your own site's code.
How to display Markdown in HTML?
Convert the Markdown to HTML, then insert the result into the body of your page, for example inside a div. The Rendered Preview tab shows how it will look, and the HTML Source tab gives the exact code to paste in. Add your own CSS to style headings, lists and code blocks.
How do I export Markdown to HTML?
Paste your Markdown into the converter, switch to the HTML Source tab, and click Copy. You can then paste the HTML into an .html file, a CMS editor or an email template. There is no account or upload involved.
