Frequently Asked Questions (FAQ)

What is an HTML Minifier?

An HTML Minifier compresses HTML files by removing unnecessary characters like whitespaces, comments, tabs, and line breaks, without changing how the HTML renders in the browser.

Will minifying HTML break my code?

No. As long as your HTML is valid before minification, the tool will preserve its structure and functionality. Comments and formatting will be removed, but the output will still work exactly the same.

Why should I minify HTML?

Minifying reduces file size, which results in faster page load times and better user experiences—especially on mobile and slow networks.

Does this tool support HTML5?

Yes. It supports all HTML standards, including HTML5, and handles modern tags like <section>, <main>, <article>, and embedded media content.

Can I un-minify code later?

You can use the HTML Beautifier tool to format your minified code for better readability, though original comments and line breaks won’t be restored.

Is the HTML processed on a server?

No. The tool operates entirely in your browser using JavaScript and WebAssembly. Your input is never uploaded or stored anywhere.

Can this tool minify inline CSS or JS inside my HTML?

It preserves inline CSS and JavaScript as-is. For full minification of embedded styles or scripts, use the CSS Minifier and JavaScript Minifier.

Is this tool mobile-compatible?
