What is Markdown ⇄ HTML conversion?
Markdown is an easy-to-write, easy-to-read plain-text markup used for READMEs, blogs and notes; HTML is the language of web pages. This tool converts between them: turn Markdown into HTML you can paste straight into a page, or turn a chunk of HTML back into clean Markdown — with a live preview of the result. Everything runs locally in your browser, with no upload.
How to use
- Paste Markdown or HTML into the input box (you can also drop in a file).
- Click Markdown → HTML or HTML → Markdown.
- Copy or download the source; expand Preview to see the formatted layout.
Common use cases
- Turn a README or notes written in Markdown into HTML for a website or email.
- Convert HTML copied from a web page into clean Markdown for your notes.
- While writing, pair it with the word counter to control length, or the text cleaner to tidy messy text.
Why did the styling disappear when converting HTML to Markdown?
Copy a chunk of HTML from a web page, convert it to Markdown, and you'll often find the colors, fonts, inline CSS and complex tables are gone — that's not breakage, it's by design: Markdown describes structure (headings, lists, links, bold), not appearance. Purely visual details can't be expressed in Markdown, so they're simplified or left as raw HTML. That's usually a good thing: you get clean, portable, maintainable plain text. Going the other way, Markdown → HTML, and want to check the layout first? Open the sandboxed preview — it runs no scripts, so it's safe.
