A README written in Markdown and a blog post pasted as HTML are the same content wearing two different outfits, this just swaps one for the other.

Markdown to HTML Converter
Convert Markdown to HTML, or HTML back to Markdown, right in your browser. Nothing you paste is uploaded.
Runs entirely in your browser using JavaScript, including a real HTML parser for the HTML→Markdown direction. Nothing you paste here is sent to a server, logged, or stored.
What this covers, and what it doesn't
Headings, bold, italic, strikethrough, inline code, fenced code blocks, links, images, blockquotes, horizontal rules, and both bulleted and numbered lists all convert cleanly in both directions. Nested lists and tables aren't supported yet, rather than guess at those and get them wrong, this tool sticks to the syntax it can convert reliably.
Markdown to HTML converter FAQ
What Markdown syntax does this support?
Headings, bold, italic, strikethrough, inline code, fenced code blocks, links, images, blockquotes, horizontal rules, and both bulleted and numbered lists. It covers what most blog posts, READMEs and comments actually use, not the full CommonMark specification: nested lists and tables aren't supported.
Does it support Markdown tables?
Not currently. Table syntax varies more between Markdown flavours than any other feature, and a half-correct table converter causes more confusion than a clear "not supported" answer. This may be added later.
Is converting Markdown to HTML and back a perfect round trip?
Semantically yes, but not always character-for-character. HTML doesn't record whether you originally wrote *italic* with asterisks or _italic_ with underscores, so a round trip normalizes that choice. The meaning and structure of the document are preserved even when the exact source characters aren't.
Can I paste HTML copied from a live webpage?
Yes. Paste it into the HTML side and it converts to Markdown using your browser's own HTML parser, so malformed or messy real-world HTML is handled the same way a browser would render it, not by a fragile set of find-and-replace rules.
Is anything I paste here uploaded?
No. All parsing and conversion happens in your browser using built-in JavaScript APIs. Nothing is sent to a server, logged, or stored.

Why a real HTML parser beats a find-and-replace script
Converting Markdown to HTML is fairly mechanical, but going the other way, HTML back to Markdown, is where most simple tools fall apart, because real-world HTML is messy: inconsistent indentation, extra whitespace, nested tags in unexpected orders. Instead of guessing with regular expressions, the HTML-to-Markdown direction here hands your HTML to the browser’s own built-in parser, the same one that renders every webpage you’ve ever visited, and walks the resulting structure. That means genuinely messy, real-world HTML gets handled the way a browser actually understands it, not the way a fragile pattern-matching script hopes it’s formatted.
What’s covered, on purpose
Headings, bold, italic, strikethrough, inline code, fenced code blocks, links, images, blockquotes, horizontal rules, and both bulleted and numbered lists all convert cleanly in either direction. Nested lists and tables are deliberately left out for now rather than shipped half-working, table syntax in particular varies enough between Markdown flavors that a “close enough” converter tends to cause more cleanup work than it saves.
A round trip won’t always give you the exact same characters back
Convert Markdown to HTML and then back to Markdown, and the structure and meaning survive perfectly, but the exact source characters might not. HTML has no memory of whether you wrote *italic* with asterisks or _italic_ with underscores, both become <em> in HTML, so a round trip normalizes that choice rather than preserving it. If you need byte-for-byte fidelity for version control diffs, keep your Markdown as the source of truth and treat HTML as an export, not the other way around.
Where this is actually useful
Pasting a Markdown README into a CMS that only accepts HTML, converting a blog post copied from a webpage into clean Markdown for a static site generator, or checking exactly how a piece of Markdown will render before you commit it, these are the moments this tool saves the most time. Everything runs locally in your browser, so pasting a work-in-progress document here doesn’t send it anywhere first.
