I built a free Markdown to HTML Converter that runs entirely in your browser

What I built

I added a Markdown to HTML Converter to devnestio — a growing collection of free, single-file developer tools.

👉 https://markdown-to-html-dev.pages.dev

Write Markdown on the left, see a live HTML preview on the right. Switch to the HTML tab to inspect syntax-highlighted output, then copy or download it.

Features

Live preview as you type — no button to click
HTML output view with syntax highlighting
Supports headings (H1–H6), bold, italic, bold+italic
Inline code and fenced code blocks (with language class)
Unordered and ordered lists
Blockquotes
Tables with <thead> / <tbody>
Horizontal rules
Links, auto-links, images
Strikethrough ~~text~~
Copy HTML to clipboard
Download as .html file with full page wrapper
Word count, line count, HTML character count stats

Why I built it

I often need to convert README snippets or documentation drafts to HTML to paste into a CMS or email template. Most online converters either send your content to a server, require sign-up, or have intrusive ads. This one is a single HTML file — zero dependencies, zero server round-trips.
