Markdown and HTML Converter
Markdown and HTML Converter
Convert Markdown to HTML with a live preview (powered by the marked library from cdnjs), or convert simple HTML back to basic Markdown.
The Markdown and HTML Converter works in both directions between the writing format people love and the markup browsers need. Markdown lets you write headings, emphasis, links, and lists with simple punctuation. When that text has to live on a web page, in an email template, or inside a content system, it must become HTML. This tool makes the jump in one click, with a live preview so you can see the rendered result before you copy anything.
Markdown to HTML is the full-featured direction. It is powered by marked, a well-known library loaded from the cdnjs network and verified before use, and it handles headings, bold and italic, links, images, lists, code blocks, blockquotes, horizontal rules, and basic tables. The raw HTML appears in the output box for copying or downloading, while the preview shows exactly how it renders.
HTML to Markdown is honestly labelled basic: it converts headings, paragraphs, bold, italic, links, simple lists, and inline code by walking the document, which covers most pasted articles and snippets, but complex nested structures may need a tidy-up. Your text itself is never uploaded; only the library file is fetched.
How to use
- Paste Markdown or HTML into the input box.
- Click Markdown to HTML, or HTML to Markdown (basic), matching your input.
- For Markdown input, check the live preview below.

Frequently asked questions
Why is HTML to Markdown labelled basic?
HTML allows many structures Markdown cannot express. The reverse converter covers the common building blocks faithfully and says so, instead of silently dropping content or pretending to be complete.
Does the Markdown converter support tables?
Yes, the marked library renders GitHub-style tables in the Markdown to HTML direction, along with code fences and blockquotes.
Is the HTML output safe to paste into my site?
It is the standard output of the marked parser for the Markdown you supplied. If the Markdown came from untrusted users, run your site's normal sanitisation, as you would with any HTML.
Is my text uploaded?
No. Only the marked library script is downloaded from cdnjs; your content stays in your browser.
