What does Markdown to HTML Converter do?

Markdown to HTML Converter transforms Markdown text into styled, ready-to-use HTML. Provide Markdown content directly or point to a URL containing a Markdown file, and the actor produces a complete HTML document with your choice of theme, syntax highlighting for code blocks, and support for GitHub Flavored Markdown features like tables, task lists, and strikethrough text.

The output can be a full HTML document with <!DOCTYPE html> wrapper or a bare HTML fragment for embedding into existing pages. Two built-in themes are available (GitHub and Minimal), plus the option to inject custom CSS. The converted HTML is saved to the key-value store for direct download and also pushed to the dataset with conversion metadata.

Features

Two input methods — paste Markdown directly or fetch from a URL
Safety caps — default max input size is 100,000 characters, configurable up to 250,000
GitHub Flavored Markdown — tables, task lists, strikethrough, autolinks, and line breaks
Syntax highlighting — automatic code block highlighting powered by highlight.js with language detection
Built-in themes — GitHub theme (clean, modern, familiar) or Minimal theme (serif, reading-focused)
Custom CSS — inject additional CSS for branding or custom styling
Fragment or document — output a complete HTML page or just the HTML body fragment
Zero-config — runs with a sample Markdown document if no input is provided
Direct download — HTML output saved to key-value store as a downloadable file
Pay-per-conversion pricing — charged per document converted

Output Format

The dataset contains conversion metadata and the full HTML output:

{
"inputLength":245,
"outputLength":1847,
"theme":"github",
"syntaxHighlight":true,
"gfm":true,
"wrapInHtmlDocument":true,
"html":"<!DOCTYPE html>\n<html lang=\"en\">\n<head>...</head>\n<body>\n<article class=\"markdown-body\">\n<h1>Hello World</h1>\n<p>This is <strong>bold</strong> and <em>italic</em> text.</p>\n</article>\n</body>\n</html>",
"scrapedAt":"2026-03-11T12:00:00.000Z"

FAQ

What is the difference between the GitHub and Minimal themes?

The GitHub theme replicates the look of GitHub's Markdown rendering with a sans-serif font, 980px max width, bordered headings, and striped tables. The Minimal theme uses a serif font (Georgia), narrower 700px width, and a cleaner reading-focused layout. Choose none for unstyled HTML and provide your own CSS via the customCss field.

Does this sanitize raw HTML inside Markdown?

No. This actor converts Markdown to HTML and preserves raw inline HTML supported by the Markdown parser. If you render output from untrusted users in a browser, sanitize the HTML in your application before embedding it.

Can I get just the HTML body without the full document wrapper?

Yes. Set wrapInHtmlDocument to false and the actor will output only the HTML body content (with optional <style> block). This is useful when you need to embed the converted HTML inside an existing page or template.

What programming languages are supported for syntax highlighting?

The actor uses highlight.js, which supports over 190 programming languages. If a language is specified in the Markdown code fence (e.g., ```python), it uses that language's highlighter. If no language is specified, highlight.js automatically detects the language.

Does this actor need a proxy?

No. Markdown to HTML Converter is a document transformation tool. When fetching from a URL, it makes a single HTTP request to download the Markdown file. No proxy is needed and it works on any Apify plan including the free tier.

Can I convert multiple Markdown files in one run?

The actor processes one Markdown document per run. For batch conversion, use the Apify API to trigger multiple runs programmatically, or chain it with another actor that produces Markdown content.
