Markdown to HTML — Publish Your Writing for the Web
Convert Markdown files to clean HTML ready for websites, blogs, and documentation portals. No build tools required.
Markdown is where you write. HTML is where people read. The gap between them should be trivially small, and yet plenty of people still manually wrap text in tags like it's 2004.
The Case for Writing in Markdown First
I won't belabor this — you probably already know Markdown if you're reading this. But the short version: Markdown lets you focus on content without fighting a WYSIWYG editor. No clicking "Bold" buttons, no wrestling with paragraph spacing, no accidentally changing the font to Comic Sans because you pasted from Word.
Write in Markdown. Convert to HTML when it's time to publish. Simple pipeline.
Where This Workflow Fits
Personal Blogs and Static Sites
If you run a Hugo, Jekyll, Eleventy, or Astro site, your content is already Markdown. But sometimes you need standalone HTML — maybe you're embedding content in a newsletter template, or you're publishing to a platform that only accepts raw HTML.
README Files
Your GitHub README renders Markdown automatically, but what if you need that same content on a website that doesn't? Convert it to HTML, drop it into your landing page.
Documentation Portals
Writing docs in Markdown and storing them in Git is standard practice. But the final output is HTML. Tools like Docusaurus and MkDocs handle this automatically during build, but sometimes you just need a quick one-off HTML file from a single Markdown document.
Email Newsletters
Some email platforms let you paste raw HTML. Write your newsletter in Markdown (fast, distraction-free), convert to HTML (properly formatted), paste into your email tool. Done.
What Happens During Conversion
The mapping is straightforward:
# HeadingbecomesHeading
boldbecomesbold- list itembecomesinside a- list item
- Code blocks get
wrappers with language classes - Links become proper
tags - Images become
tags
GFM: The Markdown Flavor That Matters
GitHub Flavored Markdown (GFM) adds features that standard Markdown lacks:
- Tables — pipe-separated columns
- Task lists —
- [x] completed item - Strikethrough —
~~deleted text~~ - Autolinked URLs — paste a URL and it becomes clickable
Syntax Highlighting in Code Blocks
If your Markdown contains fenced code blocks with language identifiers (like `javascript ), the HTML output should include appropriate CSS classes for syntax highlighting. Most converters add class="language-javascript" to the tag, which you can then style with a library like Prism.js or highlight.js.
Without this, your code blocks are just monospaced text with no color differentiation. Functional, but not great for readability.
Clean HTML vs. Styled HTML
There's a difference between:
- Clean HTML — semantic tags only, no inline styles, ready to be styled with your own CSS
- Styled HTML — includes embedded CSS so the document looks presentable standalone
Both have their place. If you're dropping the HTML into an existing website with its own stylesheet, you want clean HTML. If you're sharing a standalone file, styled HTML is more useful.
A Note on Markdown-to-PDF
If your end goal is actually a PDF rather than a web page, skip the HTML step. Go directly from Markdown to PDF. The intermediate HTML conversion can introduce rendering differences you don't want.
