FAQ
Q: Does the converted HTML include styling?
A: No, the converter outputs pure semantic HTML without any CSS styles. This gives you full control over the appearance. You can add your own CSS, use a CSS framework like Tailwind, or apply a ready-made Markdown stylesheet such as github-markdown-css for GitHub-style rendering.
Q: How do I preserve line breaks in Markdown?
A: In standard Markdown, a single line break is converted to a space. To create a hard line break (br tag), add two spaces at the end of a line before pressing Enter. A blank line creates a new paragraph. Some Markdown flavors support backslash line breaks as well.
Q: Can I convert HTML that contains raw HTML tags?
A: Yes, most Markdown parsers pass through raw HTML unchanged. This means you can embed HTML elements like video, iframe, or custom div containers directly in your Markdown. However, be cautious with user-generated content to avoid XSS vulnerabilities - always sanitize output if displaying untrusted input.
Q: Is my content secure when using this tool?
A: Absolutely. All conversion happens locally in your browser using JavaScript. Your Markdown content is never sent to any server, making this tool safe for private notes, unpublished drafts, and sensitive documentation.
