Frequently Asked Questions

What is GitHub-Flavored Markdown?

GitHub-Flavored Markdown (GFM) is an extension of standard Markdown that adds useful features like tables, task lists, strikethrough text, and automatic linking. It's the variant used on GitHub for README files, issues, and comments.

Is my content kept private?

Yes, completely. All conversion happens locally in your browser using JavaScript. No Markdown content is ever transmitted to any server or stored anywhere.

Can I convert HTML back to Markdown?

This tool only converts Markdown to HTML. For reverse conversion, you would need a specialized HTML-to-Markdown tool which handles the more complex task of cleaning and simplifying HTML markup.

Does the preview match the final output exactly?

The preview shows a styled representation of your HTML. The actual HTML output will be clean semantic markup without CSS styling. You can copy the HTML and style it according to your needs.

What if my Markdown has errors?

The parser is quite forgiving and will do its best to render your content. Minor syntax errors usually don't break the entire document - the parser will simply pass through text it doesn't recognize as valid Markdown.
