What this tool does

This HTML minifier is useful for snippets, templates and embedded markup when you need a compact version without running a build step. It keeps processing inside the browser tab.

How to use it

  1. Paste HTML into the input box.
  2. Review the minified output and size difference.
  3. Copy the compact HTML into your template or note.

Privacy

This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.

Frequently asked questions

Is my HTML uploaded?
No. The minifier runs in your browser, so the markup stays on your device.
Does it optimize JavaScript or CSS inside HTML?
No. It focuses on HTML comments and whitespace, not advanced script or style optimization.
Can it handle snippets?
Yes. It is designed for quick snippets, email blocks and template fragments.
