Markdown to HTML converter
Markdown is the authoring format for README files, Notion exports, and static site generators. Convert to HTML snippet for CMS paste, email template preview, or learning how **bold** and ```code``` map to tags — processed locally.
Input
HTML
<h1>Hello</h1>
<p>This is <strong>bold</strong> and <em>italic</em>.</p>
<ul>
<li>item 1</li>
<li>item 2</li>
</ul>

When Markdown to HTML
• When CMS accepts HTML but author writes Markdown.
• When previewing rendered README before GitHub push.
• When generating static HTML fragment without full build pipeline.
When full pipeline better
• When site uses MDX or component shortcodes — need specialized compiler.
• When GitHub-flavored Markdown tasks/checkboxes required — pick GFM-compatible parser.
• When untrusted user Markdown — must sanitize HTML output against XSS.
Flavor differences
CommonMark vs GFM vs Obsidian wikilinks — same Markdown source renders differently. Standardize flavor in team style guide.
Sanitize user content
Use allowlist sanitizer on HTML after convert — block script tags and onerror attributes.
Email HTML
Markdown tables may break in Outlook — test responsive email templates separately.
Frequently asked questions
GFM tables and strikethrough?
Depends on parser flavor — verify extensions supported.
Inline HTML in Markdown?
Many parsers pass through raw HTML — XSS risk on user content.
Code block language?
May add class language-js for Prism highlight — check output.
Full HTML document?
Output may be fragment only — wrap with html/body for standalone file.
Local?
Yes.
Reverse HTML to Markdown?
Requires HTML-to-MD converter — lossy for complex layouts.
