What does HTML minification do?

HTML minification removes comments, extra whitespace between tags, and unnecessary characters from your HTML. This reduces file size for faster loading without changing how the page displays.

Is it safe to minify HTML?

Yes, minification only removes non-essential whitespace and comments. All HTML tags, attributes, and content are preserved exactly as they are. Your page will look identical.

Can I also beautify/format HTML?

Yes, the tool includes a Format mode that adds proper indentation and line breaks to make your HTML readable. This is useful for debugging or reviewing code structure.
