HTML Minifier

Shrink your HTML by collapsing whitespace — a smaller page is a faster page.

About this tool

Every byte of indentation in your HTML travels to each visitor. This minifier collapses runs of whitespace into single spaces and drops whitespace-only text nodes between tags, which typically saves 10–30% of page weight without touching the rendering.

How to use it

  1. Paste your HTML, or click Sample.
  2. Click Minify HTML and copy the result into your template or page.

Good to know

  • HTML comments are preserved — remove them separately if you do not need them.
  • Whitespace inside <pre> blocks is collapsed too, so skip minification for pages that depend on pre-formatted text.
  • In modern setups, minifying in your build pipeline (or letting your CDN do it) is even more convenient — this tool is perfect for one-off pages and emails.
