Markdown to SEO-Ready HTML Converter
Generic Markdown converters output bare HTML with no anchor IDs, no table of contents,
and no semantic wrapper. This converter produces SEO-ready HTML: slugified heading IDs
for deep linking, an auto-generated TOC, an <article> wrapper, and
live keyword density and readability stats.

Introduction
Publishing Markdown directly often produces HTML that's technically valid but poorly optimized: no heading anchors for deep links, no table of contents, no semantic article wrapper. This converter closes those gaps automatically so your content is structured for both crawlers and readers.
How It Works
- A line-based parser converts Markdown blocks to semantic HTML.
- Each heading receives a URL-safe slugified
id(with duplicate protection). - A nested TOC is generated from H2 and H3 headings.
- Output is wrapped in
<article>and images get lazy loading. - SEO stats are computed from the stripped plain text.
Privacy
Your content is converted entirely in your browser. No content is transmitted anywhere. No API calls, no tracking.
Limitations
- Supports CommonMark-style syntax; exotic extensions (footnotes, definition lists) aren't parsed.
- Nested lists beyond one level are flattened.
- Flesch Reading Ease is an approximation based on syllable heuristics.
FAQ
Why do headings need IDs?
Heading IDs enable deep links, table-of-contents anchors, and can power jump navigation. They're essential for long-form SEO content.
Is my content uploaded?
No. Everything is converted locally in your browser. Nothing is transmitted.
