Frequently Asked Questions

What is GitHub Flavored Markdown?

GitHub Flavored Markdown (GFM) extends standard Markdown with features like syntax highlighting for code blocks, tables, strikethrough text, task lists, and automatic URL linking. It's widely used on GitHub and other platforms.

Is my content secure when using this converter?

Yes, absolutely. All conversion happens entirely in your browser using JavaScript. Your content never leaves your device or gets sent to any server, ensuring complete privacy and security.

What does HTML sanitization do?

HTML sanitization removes potentially dangerous HTML elements and attributes (like script tags, onclick handlers) while preserving safe formatting. This prevents XSS attacks and ensures clean, safe HTML output.

Can I convert HTML back to Markdown?

The tool primarily converts Markdown to HTML. While basic HTML to Markdown conversion is supported, complex HTML structures may not convert perfectly due to Markdown's simpler syntax limitations.

What file formats can I upload?

You can upload .md (Markdown), .html (HTML), and .txt (plain text) files. The tool automatically detects the format based on content and file extension.
