About HTML Minifier
Every byte of HTML the browser downloads adds to page load time, and source markup is full of indentation, comments, and whitespace that the renderer doesn't need. The HTML Minifier strips that overhead, removing unnecessary spaces, line breaks, and comments to shrink your file while keeping the page output identical.
Paste your markup and the tool returns a compact version ready to ship. It's free, runs in your browser, and works instantly with no signup. Use it as a quick build step for static pages, to trim an HTML email before sending, or to reduce the size of markup served to users so pages load faster and bandwidth costs stay lower without touching how the page actually displays.

FAQ
Does minifying change how the page renders?
No. It removes whitespace and comments the browser ignores, so the visible page stays the same.
Will my comments be removed?
Yes. HTML comments are stripped to save bytes, so keep an unminified copy if you need them for reference.
How can I reverse it?
Minification is one-way, but you can run the result through the HTML Formatter to restore readable indentation.
Is whitespace inside pre or textarea preserved?
Whitespace-sensitive content should be preserved, but review the output if your page relies on exact spacing in those elements.
Can I use HTML Minifier on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
