Frequently Asked Questions
What is GitHub Flavored Markdown (GFM) and how does it extend CommonMark?
GitHub Flavored Markdown (GFM) is a strict superset of the formal CommonMark specification. It adds support for: 1) **Tables** (`| header |`); 2) **Task lists** (`- [ ]` and `- [x]`); 3) **Strikethrough** (`~~text~~`); 4) **Autolinks** (automatically converting raw URLs into `<a>` links); 5) **Fenced code blocks** with language syntax tags.
How are line breaks handled in Markdown to HTML conversion?
In standard Markdown, a single newline is treated as a space. To force a hard line break (`<br>`), you must end the line with **two trailing spaces** or use a backslash (`\`). In GFM mode, you can enable soft-break handling to convert single newlines directly into `<br>` tags.
How does Markdown handle raw HTML tags embedded in the document?
Markdown allows raw HTML elements (like `<div>`, `<span>`, `<img>`, `<iframe>`) to be written directly in the markdown document. Our converter allows raw HTML while sanitizing dangerous execution vectors (`<script>`, `onload` handlers) to ensure safe output.
Can this tool convert HTML back to Markdown?
Yes. The converter features bidirectional conversion, allowing you to paste rich HTML markup and reverse-compile it into clean, readable Markdown syntax.
