Does this support GitHub Flavored Markdown (GFM)?

Yes, the marked library supports GFM including: fenced code blocks with syntax highlighting hints (```javascript), tables (using | pipe characters), task lists (- [ ] and - [x]), strikethrough (~~text~~), and auto-linking URLs. Standard CommonMark features are also supported.

Is the HTML output safe to embed directly on a webpage?

The HTML from this tool is not sanitized — if your Markdown input contains raw HTML (which Markdown allows), it passes through as-is. For user-generated Markdown rendered on a public website, always sanitize the HTML output using a library like DOMPurify to prevent XSS attacks before inserting it into the DOM.

How are code blocks converted?

Code blocks (indented with 4 spaces or wrapped in backticks) become HTML. Fenced blocks with a language hint (```python) get a class="language-python" attribute on the element, which syntax highlighting libraries like Prism.js or highlight.js use to apply colors.

Can I convert Markdown files from GitHub READMEs?

Yes. GitHub Markdown (GFM) is the standard this tool supports. Export or copy the raw Markdown from a README.md (use the Raw button on GitHub), paste it here, and get HTML equivalent to how GitHub renders it.

Does this handle Markdown math or LaTeX equations?

Basic Markdown with inline code blocks handles simple math notation. Full LaTeX/KaTeX math rendering is not included in this tool. For math-heavy Markdown (like Jupyter notebooks or academic papers), use Pandoc on the command line, which has built-in LaTeX and MathJax support.
