Frequently asked questions

Does this convert both Markdown to HTML and HTML to Markdown?

Yes. Use the mode selector to pick Markdown to HTML or HTML to Markdown. Both directions work in the same tool, and the output updates live as you type.

Is my content private, or is it uploaded to a server?

Everything runs 100% in your browser. Your Markdown and HTML are converted locally on your device and are never uploaded, stored, or sent anywhere.

Which Markdown features are supported?

The converter renders standard Markdown: headings, bold and italic, links, images, ordered and unordered lists, blockquotes, inline code, and fenced code blocks — the common CommonMark-style syntax.

What kind of HTML does it produce, and what does HTML to Markdown output?

Markdown to HTML produces clean, standard HTML tags. HTML to Markdown returns tidy Markdown using ATX-style headings (#) and fenced code blocks (```).

Is there a size limit on how much text I can convert?

There is no fixed limit. Because conversion happens in your browser, very large documents depend on your device's memory and speed, but typical articles, README files, and pages convert instantly.

Can I use the output in my blog, README, or CMS?

Yes. Copy the HTML or Markdown result with one click and paste it into your blog, README.md, static site generator, email, or any CMS that accepts that format.
