The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

HTML is tokenized while comments and formatting whitespace are removed where they are not text; attributes are serialized safely and raw-text elements remain protected. Element order and document structure stay unchanged.

  • Formatting removal is safer than optional-tag rewriting.
  • Raw-text and preformatted content remain protected.

Worked example

Compress HTML with comments
Remove whitespace, line breaks, and comments from formatted HTML
Input
											<div>
  <!-- navigation -->
  <nav>
    <a href="/">Home</a>
  </nav>
</div>
Output
												<div><nav><a href="/">Home</a></nav></div>

When to use this

Production pages, static-site builds, and markup snapshots minify HTML.

Edge cases

  • Whitespace in pre, textarea, and script is data.
  • A > inside a quoted attribute is not a tag close.
  • Removing a space between unquoted attributes can merge tokens.
