Frequently Asked Questions

What is the HTML Minifier?

The HTML Minifier is a tool that reduces HTML file size by removing HTML comments, whitespace between tags, and collapsing multiple spaces into one. It uses a side-by-side editor for input and output.

What does minification remove?

The minifier removes all HTML comments (<!-- ... -->), whitespace between tags (> < becomes ><), and collapses multiple consecutive spaces into a single space.

Does minification affect functionality?

No. Minification only removes unnecessary whitespace and comments that browsers ignore. The rendered output of the HTML remains identical, but the file size is smaller and loads faster.

Can I load a sample to test?

Yes. Click the Sample button to load a sample HTML document with whitespace and comments, then click Minify HTML to see the compressed output.

Is my HTML code sent to any server?

No. All minification happens locally in your browser. Your HTML code is never uploaded or transmitted to any server, ensuring your content remains private.
