What is HTML Preview Tool?

An HTML preview tool renders HTML code in a sandboxed iframe, giving you a live visual preview of how your markup will look in a browser. The preview is sandboxed for security — scripts are restricted to prevent malicious code execution. This is useful for quickly testing HTML snippets, email templates, CSS styling, and layout experiments without creating a full HTML file or setting up a development server. The preview updates as you type, providing immediate visual feedback. It is particularly valuable for email template development, where different HTML rendering engines require careful testing of markup and inline styles.
