title: HTML Minifier description: Minify HTML code to reduce file size by removing comments, whitespace, and unnecessary characters

What is an HTML Minifier?

An HTML Minifier reduces the size of your HTML files by removing unnecessary characters. This includes comments, whitespace, newlines, and redundant formatting—all without changing how your page renders.

What Gets Minified

Element	Before	After
Comments	`<!-- comment -->`	(removed)
Whitespace	`<p> text </p>`	`<p>text</p>`
Between tags	`</div> <div>`	`</div><div>`
Line breaks	Multiple lines	Single line
