How do you use this tool?
- Paste markdown or load a .md file — both paths land in the same converter.
- Pick a profile (Clean, Business, Academic, Web article) and choose standalone HTML or a body fragment.
- Optionally add the local images your markdown references — relative paths get inlined as data URLs.
- Click the Generate HTML button, check the preview and either copy it or download the .html file.
Why markdown to HTML?
Markdown is the simple language most writing workflows start in today — the notebook (Obsidian, Logseq), the AI chat (ChatGPT, Claude), the pull request, the static site generator (Hugo, Astro, Jekyll). The result is portable, diffable and readable in any editor.
The moment that same text needs to land in a CMS — Wordpress, Ghost, Strapi, Contentful — or a newsletter, an internal wiki page or a static demo, you need HTML. This tool builds the bridge. You hand it markdown, it hands you HTML, no detour through external servers.
How does the conversion work?
Markdown is parsed via a well-established open-source library that
understands
GitHub Flavored Markdown
including tables, task lists, fenced code with language hints and
autolinks. The result is an HTML fragment that gets optionally
sanitised — <script> tags, <style> blocks, on* event handlers and
javascript: URLs are removed via a respected
XSS-protection library.
Standalone mode wraps the fragment in a full HTML shell with
<!DOCTYPE html>, <head> and an embedded stylesheet. The stylesheet
depends on the profile and is hard-coded — no external fonts, no
external CSS files. The result stays offline-capable and independent of
a server connection.
What are common use cases?
- CMS migration. A pile of markdown notes becomes HTML that lands in WordPress or Ghost piece by piece.
- AI chat to newsletter. A long answer from the AI chat gets formatted for the newsletter editor.
- Static demo page. A README or specification becomes a self-contained HTML file for internal docs.
- Editorial workflow. Writers work in markdown, editors get the HTML to review in a browser.
- Email templates. Markdown becomes HTML that lands as the body of an email template.
What stays intact?
Preserved: heading hierarchy (<h1> to <h6>) with auto-generated
IDs, paragraphs, ordered and unordered lists with nesting, tables with
header rows, inline formatting (bold, italic, inline code,
strikethrough), hyperlinks ([text](URL)), block quotes, fenced code
with language class, images as <img>.
Intentionally removed (in default sanitise mode): <script> tags,
<style> blocks, <iframe>/<object>/<embed>, all on* handlers,
javascript: URLs. That is the default policy because the output goes
to third-party systems.
Opt-in extension: turn the sanitiser off if you really need inline HTML — useful when the markdown is trusted and contains something like custom embed codes.
How does the tool keep my markdown private?
If you just drafted an internal memo or a customer briefing in markdown, the last thing you want is for it to be uploaded somewhere. Nothing gets uploaded here.
Markdown is parsed in your browser tab and the HTML result is generated in the same tab. Open the Network panel of the developer tools and watch — no request, no upload, no server communication. The paste field works entirely client-side and the optional images are embedded locally as data URLs, not transferred.
Which related document tools exist?
More tools from the converter ecosystem worth knowing:
- Markdown to PDF — same markdown input, finished PDF via the browser print path.
- Markdown to DOCX — Word file with real heading styles and repeating table headers.
- HTML to Markdown — the reverse direction if your source is already HTML.
