About This Tool
Renders Markdown source as HTML. Supports CommonMark by default, with optional GitHub Flavored Markdown (tables, task lists, strikethrough, autolinks) via `gfm=true`. HTML sanitization is applied by default to strip scripts and unsafe handlers.
The response includes the rendered HTML plus metadata: word count and a generated table of contents.
Why Use This Tool
- CMS rendering — Render user-supplied Markdown in comments, posts, and docs
- Static site builds — Convert Markdown pages to HTML during deploys
- Newsletters — Render Markdown drafts to HTML for email composition
- Documentation — Produce HTML docs from Markdown source
Frequently Asked Questions
Is the HTML safe to render?
When `sanitize=true` (default), scripts, iframes, and unsafe attributes are stripped.
Are code blocks syntax-highlighted?
No — this endpoint produces semantic `<pre><code>` only. Apply client-side highlighting (Prism, highlight.js) if needed.
What Markdown extensions are enabled?
CommonMark by default. `gfm=true` adds tables, task lists, strikethrough, and autolinks.
