Frequently Asked Questions
How does the Markdown to HTML Converter work?
The tool uses the marked.js library to parse Markdown syntax into an abstract syntax tree (AST) of tokens (headings, paragraphs, emphasis, code blocks, etc.), then renders each token into its corresponding HTML element. The output HTML is sanitized with DOMPurify to prevent XSS from malicious input. The live preview renders the HTML in a sandboxed container that updates on each keystroke via debounced input.
What Markdown features are supported?
All standard Markdown syntax including headings, bold, italic, links, images, code blocks, blockquotes, lists, tables, and horizontal rules. The output is clean, semantic HTML.
Can I see a live preview as I type?
Yes. The preview updates in real time as you type or edit your Markdown. The left pane shows your Markdown source and the right pane shows the rendered HTML output.
Can I copy the raw HTML output?
Yes. Copy the generated HTML source code with one click to paste into your website, email template, or CMS. The HTML is clean and ready to use.
