What does minifying HTML do?
Minification removes HTML comments and collapses redundant whitespace between tags without changing what the page renders or how it behaves. It's a small, safe win on page weight, especially for static or server-rendered HTML that ships as-is.
What this tool preserves
Content inside <pre>, <textarea>, <script>, and <style> is left untouched, since whitespace there can be meaningful or would break the embedded code. Everything else has excess whitespace collapsed to a single space.
Frequently asked questions
Does minifying change how my page looks?
It shouldn't — HTML collapses adjacent whitespace when rendering anyway, so removing extra whitespace between tags has no visual effect in normal flow content. Whitespace-sensitive areas like <pre> blocks are left alone by this tool.
Will this break inline JavaScript or CSS?
No — content inside <script> and <style> tags is left exactly as-is; only whitespace in the surrounding HTML markup is collapsed.
Is my HTML uploaded when I use this tool?
No. Minification happens instantly in your browser — nothing is sent to a server.
